Generally speaking, late Saturday night is not the time for rational decisions. Late Saturday night is when people make the kinds of decisions that they won’t even remember until halfway through their eggs on Sunday and whose logic they’ll struggle to puzzle out for years to come. But just before midnight on Saturday, Jeff Passan revealed that the Nationals and the Mets made a perfectly reasonable swap. The Mets, currently half a game ahead of the Diamondbacks for the final NL Wild Card spot, bolstered their outfield and added a much-needed left-handed bat by sending 24-year-old right-handed pitching prospect Tyler Stuart to the Nationals in exchange for half a season of the resurgent Jesse Winker. After putting up a dreadful -0.8 WAR in an injury-shortened 2023 campaign, Winker is running a 126 wRC+ and has put up 1.3 WAR, fourth-best among Washington’s position players. Winker also spent his early childhood in upstate New York and has been vocal about his appreciation for Mets fans.

Winker got into Sunday’s game with his new team, entering as a replacement and playing left field, though his ultimate destination might be in right. Winker hasn’t played more than 100 innings in right field since 2019, but with Starling Marte out since June 22 due to a knee injury, that seems like the most logical fit. The Mets are currently platooning Jeff McNeil and Tyrone Taylor out there. Against righties, Winker could allow McNeil to move second base, pushing Jose Iglesias, who started out red-hot but has just one hit over his past six games, back into a bench role.

We’re barreling toward the trade deadline, which means it’s time for teams to decide if they’re in, out, or Tampa Bay. After picking which of those categories they fit into, the next move is obvious. In? Trade for a reliever. Out? Trade away your relievers. Tampa Bay? Make 10 moves, with more moving parts than you can possibly imagine. All of those types were on display this weekend, so let’s round up some reliever trades.

The Brewers and Rockies got the party started with a simple swap: Nick Mears to the Brewers, Bradley Blalock and Yujanyer Herrera to the Rockies. This one is basically what you’d expect from a deadline deal. The Brewers need relief help; they have nine pitchers on the IL, and while they just got Devin Williams back, they lost Bryan Hudson to injury earlier this week. It’s been an uphill battle to fill innings in Milwaukee this year. Mears slots right into the middle of the bullpen, helping to lengthen the number of innings the Brewers can cover with high octane arms. The Brewers have the fewest innings pitched by starters this year, so that depth really matters.

While trades of relievers at the deadline are rarely the hottest moves featuring the best prospects, there are usually a lot of them. As the summer reaches its peak, contenders start to think about their bullpens down the stretch and beyond, and with modern bullpens seemingly as densely populated as the cover of Sgt. Pepper’s, there’s always room to add a quality arm. Let’s dig through them!

Editor’s Note: This reliever roundup doesn’t include the more recent trades for Carlos Estévez, Nick Mears, and Jason Adam. Ben Clemens will cover those moves in a separate post.)

The Arizona Diamondbacks acquired LHRP A.J. Puk from the Miami Marlins for 1B/3B Deyvison De Los Santos and OF Andrew Pintar

Don’t focus too much on the raw ERA or unimpressive walk rate when judging the merits of Arizona’s trade for A.J. Puk. Partially in response to their myriad rotation injuries in the spring, the Marlins took Puk’s attempt to get back into the rotation seriously, and he started the season there after a successful spring. I still think that was a well-founded experiment, but it didn’t pay dividends for Miami. Puk was absolutely dreadful as a starter, and it wasn’t long before he landed on the IL with shoulder fatigue. His four starts resulted in a 9.22 ERA, a 6.29 FIP, and an alarming 17 walks in 13 2/3 innings. He was moved back to the ’pen upon his return in mid-May, but the damage to his seasonal line was so significant that it still looked underwhelming at the time of the trade (4.30 ERA, 3.62 FIP, 44 IP).

As he has the last few years, Puk has dominated as a reliever; across 30 1/3 relief innings with the Marlins, he had 33 strikeouts and, perhaps most importantly, only six walks. The result was a 2.08 ERA/2.42 FIP, with batters managing a bleak .159/.204/.252 against him. The Diamondbacks are short on lefty relievers, with Joe Mantiply shouldering a very large share of the southpaw burden. Puk has historically been better against righties than Mantiply, so he can be used in more situations.

In return, the offense-starved Marlins pick up a couple of possible bats to add to their farm system. With a .325/.376/.635 and 28 homers combined at two levels in the high minors this year, Deyvison De Los Santos looks impressive at first look, but it’s important to contextualize those numbers. He’s playing in some very high offensive environments and there’s a lot of hot air to remove from those numbers to turn them into expected MLB performance. ZiPS translates his 2024 minor league performance to .263/.302/.428 in the majors and projects for wRC+ lines between 95 and 110 in the coming years with the Marlins. Now, that’s enough for the Marlins to be interested in him and chase any upside, but don’t be shocked if he’s not an offensive force.

Similarly, ZiPS translates Andrew Pintar’s season at .235/.302/.365 and doesn’t see a ton of growth from him offensively, viewing him as most likely to be a spare outfielder if he reaches the majors. I talked a bit with my colleague Eric Longenhagen about him on Friday and Eric still grades Pintar as a fifth-outfielder type, which is about how ZiPS evaluates him. Still, as with De Los Santos, Pintar’s interesting enough for a team like the Marlins to take a chance on him and give him an extended look; projections are frequently wrong, after all, by design!

The Seattle Mariners acquired RHRP Yimi García from the Toronto Blue Jays for OF Jonatan Clase and C Jacob Sharp

With the Blue Jays as short-term sellers, it’s hardly surprising to see them trade Yimi García, who is a free agent at the end of the season. His three-year, $16 million deal turned out to be a success for the Jays; he’s been worth 2.7 WAR and put up a 3.44 ERA/3.28 FIP over 163 appearances across two-plus seasons. This season has arguably been his best, as he’s striking out nearly 13 batters per nine innings. With Gregory Santos limping a bit after a knee injury – not believed to be severe – García slots in behind Andrés Muñoz in the Mariners’ bullpen pecking order. Seattle’s relief corps has been in the middle of the pack, but adding García to a group that features Muñoz, a healthy Santos, and Taylor Saucedo gives the M’s an excellent quartet of high-leverage guys, which could be crucial in what’s shaping up to be a tight AL West race.

Jonatan Clase was listed with a FV of 40 earlier this month when Eric ran down the top Mariners prospects, but with Julio Rodríguez entrenched in center field and backed up by other outfielders who can capably cover the position (namely Victor Robles, Cade Marlowe, and even, in a pinch, newly acquired Randy Arozarena), Clase’s ability to do so was simply less valuable in Seattle. Beyond that, the team needs more thump in its lineup at this point, and that’s not Clase’s speciality. For the Jays, Kevin Kiermaier is a free agent after the season and the organization has a real lack of center field candidates anywhere near the majors. ZiPS projects Clase at .218/.291/.373 with an 84 wRC+ for 2025 but views him as an above-average defensive center fielder, suggesting that he’s at least a reasonable stopgap option or a useful role player for Toronto. Jacob Sharp has been off the radar as a prospect, a fairly small catcher who is hitting decently well, albeit as a 22-year-old in A-ball.

The New York Mets acquired RHRP Ryne Stanek from the Seattle Mariners for OF Rhylan Thomas

The Mets have an extremely unimpressive bullpen once you get past Edwin Díaz, and now that they are firmly in contention for an NL Wild Card spot this season, they are looking to improve their relief corps. Ryne Stanek hasn’t excelled in Seattle, but the veteran reliever still throws in the high-90s, is durable, and misses bats. Guys like that will always resurface. Especially after trading for García, the Mariners have better options than Stanek to pitch in high-leverage, non-save situations. But that’s not the case in Queens, and he’s a welcome addition to the bullpen.

Rhylan Thomas isn’t a high price to pay and he largely fills a similar role to the departed Clase in Seattle’s organization, though he’s a different type of player. As a high-contact hitter, Thomas may fare well in pitcher-friendly T-Mobile Park. ZiPS sees Thomas as a .263/.313/.333 hitter with plus defense in the corners in 2025.

The Tampa Bay Rays acquired RHRP Cole Sulser from the New York Mets for cash

Cole Sulser is a relative soft-tosser who relies on deception. He had a big breakout season in 2021, but after a trade to the Marlins, he struggled with his command in ’22 and had his season marred by a lat injury that landed him on the 60-day IL. A shoulder injury ruined his 2023 and he’s spent ’24 trying to rehabilitate his value in the minors for the Mets, with mixed results. This is the third time the Rays have traded for Sulser in his career, so they seem to see something in him, and given Tampa Bay’s record with random relievers, I wouldn’t be shocked if he became useful for the Rays next season.

Cash is slang for currency, which can be exchanged for goods and services. It can be vulnerable to inflation, and because of this, it doesn’t represent a stable medium of exchange in some countries. But cash also has the benefit of being very flexible.

The Chicago Cubs acquired RHRP Nate Pearson from the Toronto Blue Jays for OF Yohendrick Pinango

Nate Pearson was rightly a hot prospect back in the day, and there were good reasons to think he’d play a key role in Toronto. Both scouts (he graduated at a FV of 55 here) and projections (ZiPS was a fan) thought a lot of his abilities, but the question was how he’d hold up physically as a starter. This worry turned out to be a real issue, and for the most part since 2019, his seasons have been marred by a wide variety of nagging injuries, costing him significant development time. Pearson throws hard, but he’s still rather raw, a problem given that he turns 28 in a few weeks and he has only two years left of club control after this one — not a lot of time for a reclamation project. The Cubs have decided to take a shot at fixing him. They are short-term sellers, but if Pearson pays off, he could be a significant player for their ’pen in 2025 and ’26.

Yohendrick Pinango is rather raw as well, a corner outfielder with decent power upside who hasn’t really shown that home run pop in the minors so far. The Cubs are kind of stacked with raw, interesting outfield prospects, while the Jays are rather short of them, making Toronto a better home for Pinango. ZiPS only translates Pinango’s 2024 season to a .344 slugging percentage; he hit well in High-A, but that was as a 22-year-old in his third stint there. Like Pearson, Pinango’s a lottery ticket.

The Boston Red Sox beat the New York Yankees 9-7 on Friday night, and regardless of which team you might have been rooting for, the game was an absolute gem. The lead changed hands fives times, the 28 combined hits included four home runs — one of them a titanic 470-foot blast by Aaron Judge — and the tying runs were on base when Kenley Jansen recorded the final out for his 440th career save. Moreover, the atmosphere at a packed Fenway Park was electric throughout. It was as close to a postseason atmosphere as you will find in July.

The loss was New York’s fifth in sixth games, so I was admittedly a bit apprehensive about asking Aaron Boone a particular question prior to yesterday evening’s affair. I did so anyway. Prefacing it by relating a press box opinion that it had been as entertaining as any played at Fenway all season, I wanted to know if, as a manager, he allows himself to think about the aesthetics of a baseball game in that manner.

His answer didn’t disappoint.

“I always try to have a little appreciation for that,” Boone replied. “Especially with what we’ve been going through as a club. We’ve struggled. There are a handful of games where I’ve felt that way, like, ‘Man, this is a really good baseball game going on.’ When you come out on the bad end it kind of sucks, but you try to have that appreciation for ‘That was a really good one.’ Hopefully we can start to be on the right side of those.” Read the rest of this entry »

After a somewhat slow start to this year’s trade deadline, one of the better pitchers available has a new team, with Zach Eflin heading from Tropicana Field to the land of Old Bay and Natty Boh. (That’s Baltimore, for those of you unfamiliar with properly seasoned shellfish and/or nostalgic mass-market budget lager.) Heading back to the Rays from the Orioles are three prospects, right-handed starter Jackson Baumeister, infielder Mac Horvath, and outfielder Matthew Etzel. In his second season with the Rays, Eflin has a 4.09 ERA and 3.65 FIP over 19 starts, good for 1.8 WAR.

Entering the season, the depth of Baltimore’s rotation was something of a concern. Acquiring Corbin Burnes in his walk year did a lot to alleviate the situation, and with the seventh-best ERA and 10th-best WAR in baseball, the rotation hasn’t really hindered the Orioles’ quest to win their first World Series trophy since I was just a wee cynical kindergartener. Still, despite their positive starting pitching rankings, the water has gotten pretty choppy. Both Kyle Bradish and John Means underwent Tommy John surgery in June, and Tyler Wells is out for the season after an internal brace surgery on his UCL in . Further complicating matters is the fact that Cole Irvin, a pleasant surprise in the season’s early going, had a worse June than the Soviet army in 1941. Cade Povich was decidedly mediocre in his debut and was optioned to Triple-A earlier this month, and Chayce McDermott still has command issues to iron out. The team has good reason to expect more from those two in the future, but that future isn’t going arrive this week, and the team needed a bit more certainty in the rotation behind Burnes and Grayson Rodriguez.

I updated the Top 100 Prospects list today. This post goes through the pitchers and why they stack the way they do. Here’s a link directly to the list, and here’s a link to the post with a little more detail regarding farm system and prospect stuff and the trade deadline. It might be best for you to open a second tab and follow along, so here are the Top 100 pitchers isolated away from the bats. Let’s get to it.

This has been a relatively down year for the no-hitter. Entering play yesterday, Ronel Blanco’s masterpiece during the first week of the season was the only no-no of the season, a far cry from the first half of 2021, which saw six solo no-hitters in 41 days, along with the ever-increasing number of combined efforts in the modern era. And while the rookie Blanco was the unlikely hero in baseball’s first no-hitter of 2024, it was an established star who broke the nearly four-month drought: Dylan Cease.

We haven’t written about Cease since his blockbuster trade to San Diego, so let’s check in on his debut season with the Padres. By most metrics, he’s taken a leap forward with his new team. His 32.5% strikeout rate and 7.6% walk rate are both the best of his career, the latter mark a huge development from someone who’s always run a walk rate in the double digits. Both PitchingBot and Pitching+ view 2024 as his finest season; his 3.03 FIP and 3.01 SIERA are also personal bests, and his 3.50 ERA sits behind only his mark in 2022, when he finished as the AL Cy Young runner-up.

CJ Abrams is one of the blossoming stars in today’s game. Entering play Friday, the 23-year-old shortstop who recently made his first All-Star appearance is batting .260/.333/.467 with 15 home runs, 16 stolen bases, a 122 wRC+, a .344 wOBA, and 1.9 WAR over 422 plate appearances. During the first month of what’s turned out to be his breakout season, I wrote about Abrams’ stellar offensive start. About a month-long slump followed, but he bounced back in late May and is showing that his plus-offensive profile is here to stay.

Now in his third season, Abrams is proving he can be the centerpiece that the Nationals can build around. Beyond his bat, his aggressive baserunning and speed make him one of the most dynamic young players in the game. Last year, despite his inconsistencies at the plate, Abrams was a menace on the paths. Thanks to his 28.6 ft/sec sprint speed (82nd percentile), according to Baseball Savant, he was worth +3 runs on the bases; he swiped 47 bags and had a 9.2 BsR.

This year, Abrams has been just as fast, but at least according to BsR, he is no longer a plus baserunner. (Baseball Savant says he’s been worth +1 run on the bases this year, which ranks 71st; he was no. 23 on last year’s leaderboard.) That’s because he’s been caught stealing 10 times already, with five of them coming via pickoffs, plus another pickoff that didn’t come on an attempted steal.

In 2023, Abrams went 47-for-51 on stolen base attempts. If he took off, the odds were in his favor. Pitchers weren’t exposing him for taking too big of leads or being overly aggressive. This year, his precipitous drop to 16-for-26 has been staggering. When a player who was so recently a great basestealer runs into a slump like this, it warrants a deep dive into understanding what exactly is going on. There are a few components of the steal that we have to pay attention to when trying diagnose this type of issue: the lead, the jump, and the situation. Let’s go through each piece and find out what’s gone wrong for Abrams. Here is a compilation of his pickoffs this year:

None of these look particularly great. He was either off balance or out by a good margin on almost every play. We can trace some of this back to his leads, so let’s start there. There are two main ways to take a lead against a lefty if you are thinking about attempting to steal second. You can take a normal 12-foot lead like Abrams did against Sean Manaea and then run on the pitcher’s first movement (as soon as the pitcher lifts his leg). Or, you can take a larger, one-way lead to possibly draw a throw over and get a feel for the pitcher’s pickoff move.

For the first one, you want to stay close enough to the bag so the pitcher doesn’t pick you off, but you want to get far enough out there that you have a good chance to be safe at second even if he does throw over; as soon as the pitcher lifts his leg, you break for second. For the one-way lead, you are an extra step or two toward second, but you are not attempting to steal on the upcoming pitch. Instead, you put all your weight on your left foot, toward first base, so you can dive back safely if the pitcher attempts to pick you off. If the pitcher doesn’t throw over, you are timing up his delivery so you can get a better jump if you decide to steal later. That doesn’t appear to be what Abrams was doing in the video above. All three times he has been picked off by a lefty this season have come early in the count, twice on the second pitch of the plate appearance and once on the first pitch.

In the 1-0 count against Manaea, Abrams took a standard 12-foot lead. He attempted to go on first movement but realized he would’ve been dead to rights, so he hesitated into shuffles instead. He should have just kept going and forced Pete Alonso to make a play. This was the most obvious mental mistake of the three. Against left-handers Kirby Snead and Alex Vesia, Abrams went on first movement, but because each pitcher expected him to go and was well-prepared to throw over, the defense caught him easily. As a pitcher, you know Abrams is an aggressive runner, but why in these two cases was it so easy? Well, this is a good time to point to Abrams’ tendencies.

Eight of his 16 swipes this season came on the first pitch, and of his six pickoffs, four were on the first pitch. If you’re a pitcher looking to control Abrams’ aggression, do it early. For lefties, it’s even easier to execute because you’re facing him as he leads off first. This goes back to the situational aspect I brought up before. Pitchers are smart, and these are the exact types of tidbits they become aware of as they prep for a good basestealer. Combine the early counts with pitchers being more willing to throw over if they haven’t yet used their allotted disengagements, and you have tough recipe for success. A potential solution here is for Abrams to wait for deeper counts before trying to steal.

The right-handed pitchers in these clips are equally prepared for Abrams to run early. He often uses the vault lead against righties. As a reminder, the vault lead is when you take your primary lead at about nine or 10 feet instead of 12. You take your same athletic stance and shuffle about 2-3 feet just as the pitcher lifts his leg. The momentum from your vault helps you accelerate into your sprint quicker than you would with a traditional, static lead, albeit with risks. The key to a successful vault lead is not the size of your shuffle; it’s your timing. If you venture too far out before or after the shuffle, or you mistime your vault and are in the air when the pitcher disengages to throw over, you risk getting picked off.

At times this season, Abrams has made both mistakes on his vault leads: Either his primary leads or his shuffles are too large. The vault lead is more technical than physical, based more on mechanics than reflexes and pure speed. Abrams is fast enough and reacts quick enough to steal bases with a traditional lead against favorable matchups, so if I were him, I would temporarily abandon the vault lead and work on getting the fundamentals down again before bringing it back in games.

Before letting you go, I also want to look at the plays on which Abrams was thrown out by a catcher to see if these caught stealings were because of bad decisions, poor jumps, or good defense. Here is a quick reel:

Off the rip, there are three plays that stick out. If you’re going to attempt steals against Gabriel Moreno and Patrick Bailey – perhaps the two best throwers in the sport – you have to pick your spots wisely. In the Arizona game, the Nationals were up two runs and the count was 0-2, providing a good opportunity to run and try to avoid a double play; against the Giants, my guess is he wanted to get into scoring position with two outs. These are valid enough reasons to run despite the poor matchups and are not comparable to the pickoff mistakes.

In the game against the Red Sox, righty Brayan Bello, who has an extremely quick slide step, was on the bump. Even runners who are faster than Abrams would have trouble reaching second safely when a pitcher delivers a 96-mph heater in the middle of the zone on a slide step. And perhaps not surprisingly, this came on the first pitch of the at-bat.

On the first play in the clip, against the Rockies, Abrams attempted to swipe third with a left-handed batter up. Even without seeing the quality of the lead that Abrams took, this was a bad decision. Dakota Hudson never took his eye off of Abrams before he delivered his pitch, making it much more difficult for him to get a good jump. On top of that, catchers love when this happens because with a lefty batting they have a clear throwing lane to third base; when righties are hitting, catchers have a more difficult play because they need to step back and around the batter before firing. Even with an inaccurate throw from catcher Jacob Stallings, Abrams was canned.

Abrams is an aggressive runner. Without his aggressions, he wouldn’t be able to steal nearly 50 bases in a season like he did last year. This isn’t something you want to take away from him. However, he does need to learn from these mistakes so he can use his speed and aggression more effectively. Most of these pickoffs and unsuccessful steals resulted from some a combination of being predictable and getting too jumpy. The good news is he is talented enough to make the necessary adjustments. Once that happens, we’ll get to see a much more complete version of Abrams, one who can swipe 40 bags at a high clip and pepper the gaps with line drives.

The Mariners have suffered through a pretty terrible stretch over the last five or so weeks. After blowing a 10-game lead in the AL West during a 24-game span — the quickest that any team has ever surrendered such a large divisional lead — they enter play Friday a game behind the first-place Astros and 3.5 games out of the final AL Wild Card spot. Over their last 30 games, they’ve gone 10-20 and have scored a measly 3.4 runs per game while their pitching staff has allowed the fewest runs in the American League. Things got worse earlier this week, when they were swept by the Angels and lost both Julio Rodríguez and J.P. Crawford to injuries. Rodríguez sprained his right ankle and there is no timetable for his return; Crawford, who fractured his right pinky, is expected to miss 4-6 weeks. Even before those two core pieces of the beleaguered lineup landed on the injured list, Seattle desperately needed an infusion of talent onto their roster.

With that need exacerbated by those two injuries, the M’s wasted very little time making their first addition ahead of Tuesday’s trade deadline: On Thursday night, they acquired outfielder Randy Arozarena from the Rays. In exchange, Tampa Bay received minor league outfielder Aidan Smith (40 FV), right-handed pitcher Brody Hopkins (45+ FV), and a player to be named later. Dan Szymborski put together a hypothetical version of this trade just a few days ago and nailed all the broad strokes: The Mariners got the offensive upgrade they needed and the Rays got some really interesting prospects that they can now sculpt.

The former AL Rookie of the Year and All-Star got off to a agonizingly slow start to the season; through the first month of play, he was slashing .143/.220/.241 with three home runs, a strikeout rate just a hair below 30%, and a 37 wRC+. He started to pull himself out of his slump in May (104 wRC+) but was still underperforming. Since June 1, though, he’s been one of the hottest hitters in the league, putting together a .284/.397/.507 slash line with seven home runs and a 161 wRC+ across 179 plate appearances.

As Jay Jaffe noted back in April when he checked in on Arozarena’s woes, and then again during his replacement level killers series last week, “Rays hitting coach Chad Mottola had expressed the belief that Arozarena’s desire to use the whole field more often, in an effort to make himself an even better hitter, may have backfired.”

That change in approach might be related to his diminished contact rate early in the season, particularly on pitches in the strike zone.

His rebound in June and July aligns pretty clearly with his ability to put the bat on the ball when pitchers leave their pitches over the plate. And thankfully, almost all of his other plate discipline metrics are either improved or within range of his established norms.

He’s still making excellent swing decisions at the plate — his SEAGER is in the 84th percentile among all batters this year — and his batted ball metrics are as solid as ever. That two-month funk to start the season is dragging his overall offensive line way down, but make no mistake, it certainly appears as though Arozarena has put those struggles behind him.

He’ll immediately slot into the middle of the Mariners lineup as their regular left fielder and will give them a potent bat to help protect Rodríguez whenever he returns while providing dynamic run production himself. Perhaps more importantly for Seattle, Arozarena won’t reach free agency until 2027; he’s making $8.1 million this season, his second year of arbitration. The organization has developed a mostly homegrown rotation that has emerged as one of the best in the majors, but over the last few years, the Mariners have been reluctant to use free agency to improve their lineup. That makes it imperative for the front office to be aggressive on the trade market to acquire impact batters who can help the Mariners not just this season but throughout this competitive window, before their group of pitchers either breaks down or becomes too expensive to keep together. Arozarena boosts this lineup now and in the future.

For the Rays, this trade comes at an interesting time. They’re actually only a half game behind the M’s in the AL Wild Card standings and their pitching staff is getting a lot healthier. Shane Baz just came back from his Tommy John rehab earlier this month, Jeffrey Springs should be returning to the majors within a week or so, and Drew Rasmussen isn’t that far behind Springs. Tampa Bay has been hovering on the edge of the AL playoff picture for nearly the entire season, but a late-season surge wouldn’t have been out of the question. By moving Arozarena at this point in the season, the Rays have indicated that they’re more interested in ensuring they’re set up well for the future than in hoping for a long-shot playoff run over the next few months.

The timing also says a lot about what they think of the prospects they’re getting in this deal. Arozarena’s escalating salary now that he’s in the middle of his arbitration seasons had made him an obvious trade candidate this year, but the Rays could have waited until the offseason to move him if they didn’t like the players they were getting in return. That they acted now indicates they liked this package enough to pounce on it five days before the trade deadline. On the very fresh Mariners prospect list that Eric Longenhagen recently put together, Hopkins was ranked seventh and Smith 21st.

In a Seattle organization that is notorious for helping pitchers develop into the best versions of themselves, Longenhagen called Hopkins the most exciting pitching prospect in the system. He’s a converted outfielder who was selected in the sixth round of last year’s amateur draft and is still very new to pitching. He’s got a low-slot release with some deception in his mechanics, and that arm slot creates a ton of ride and life on his mid-90s heater and gives him a wipeout slider that flashes plus. He still needs to develop a third pitch to flesh out his repertoire to reach his ceiling as a mid-rotation starter, but even if he doesn’t, he appears to have a pretty nice floor as a two-pitch high-leverage reliever. He’s already 22 years old, which makes him pretty old for Single-A, where the Mariners had placed him in their organization, but as he gains development time as a pitcher, he should move quickly up the ladder.

As for Smith, he was Seattle’s fourth-round pick in last year’s draft and has hit very well in his brief professional career. A prep selection out of Texas, he’s an athletic outfielder with plenty of speed to stick in center field. He was slashing .284/.402/.470 at Single-A Modesto, and it looks like he had made the necessary adjustments to his swing to improve his feel for contact. He’s a ways away from the majors, but his physical projection and successful start to his minor league career were both intriguing enough for Tampa Bay to take a chance on him.

Even with Arozarena in the fold, the Mariners should not be done adding to their roster. Their offensive issues are too deep to be solved by one player. Even after moving Hopkins and Smith, Seattle has enough highly regarded prospects available to move for another big splash. They’ve been linked to Jazz Chisholm Jr. and Vladimir Guerrero Jr. over the last few days — both would be significant upgrades to the black holes the Mariners are running out at second and first base this year. Given the Mariners’ place in the standings and the state of their roster and farm system, this move for Arozarena should not preclude them from continuing to improve their offense over the next few days.

On July 27, 2018, a piece titled A Conversation With Oakland Pitching Coach Scott Emerson was published here at FanGraphs. Notable about the piece is that a question I’d asked about a particular pitcher, Daniel Mengden, ended up segueing into a variety of related topics. As I noted at the time, Emerson loves discussing his craft.

Six years later, that hasn’t changed. A few days before the All-Star break, I once again sat down with Emerson at Fenway Park. I wanted to ask him about pitch counts — the night before, A’s starter JP Sears threw 114 pitches across 5 2/3 innings in Oakland’s 5-2 win over the Red Sox — and expected our chit-chat would last roughly five minutes. Not surprisingly, we talked a good bit longer. Moreover — again not a surprise — we ended up discussing not just what I’d intended, but other aspects of the art and science of pitching as well.
