We do not live in an exciting time for record chases. Ichiro’s single-season hits record is perfectly safe, as is Barry Bonds‘ home run record. The records that are getting broken are of the team variety, and even those seem to be as much a sign of the times as they are reflective of a team’s historical excellence. The team home run record, for example, is about to fall for a second straight year, with the Minnesota Twins on pace to demolish the 2018 Yankees’ mark. The record for strikeouts recorded by a pitching staff has been broken in each of the last two seasons as well.

Still, there is at least one team record in jeopardy that’s worth a bit more discussion. In the first half of the season, the Arizona Diamondbacks stole 50 bases in 56 attempts, good for an 89.3% success rate. The all-time record, set by the 2007 Philadelphia Phillies, is 87.9%.

Is it the sexiest record in sports? It is not. Is that a jaw-dropping gap between the record pursuer and the current record holder? Nope! But I’m not here to talk about what it would mean if the D-backs edged the 2007 Phillies out by a decimal point or two at the end of the season. What I’d like to talk about instead is what it would mean if Arizona finished the year with a 90% success rate.

Before we talk about a 90% stolen-base success rate, let’s discuss an 80% success rate. Since the beginning of the live ball era, just 38 teams in major league history have finished a season with a stolen-base success rate of 80% or higher. Here are those 38 teams: Read the rest of this entry »

Lourdes Gurriel Jr. needed a reset. It was April 14, and he was hitting .175/.250/.275 over 44 plate appearances. After starting the season 2-for-27, he’d recorded hits in four straight starts, but the Toronto Blue Jays still saw enough significant problems to warrant time in the minor leagues. They sent him down to Buffalo, where he hit .276/.308/.480 with a 94 wRC+ in 31 games. It was a perfectly cromulent performance, but nothing that suggested he was a brand new man capable of wreaking havoc on big league pitching.

Then in his first game back in the majors on May 24, Gurriel hit his first homer of the season. The next day, he homered again, and the day after that, he homered again. He hit another three games later, was quiet for a week after, and then rattled off 10 homers in his next 18 games. That included back-to-back two-dinger performances last Wednesday and Friday. Since his return from the minors, no one in baseball has better numbers than Gurriel in homers (14), slugging percentage (.750), wOBA (.466), or wRC+ (199). Just three hitters have produced more WAR.

Gurriel’s hot streak is a surprise, though not because his talent has ever been in doubt. A native of Sancti Spiritus, Cuba, he was known in his young Havana Industriales career for being an athletic player with a nice glove, but he began to break out with the bat by hitting .344/.407/.560 in the 2015-16 season. That’s the kind of performance that will help put a player’s name on the map, but in Gurriel’s case, plenty of people already knew his name. His father, Lourdes Gourriel, is a former Cuban National Series MVP winner and won a gold medal with Team Cuba in the 1992 Olympics. Meanwhile, his older brother Yuli had already been a star in Cuba for the better part of a decade. Lourdes Gurriel Jr. definitely had strong baseball genes, and in November 2016, he signed a seven-year, $22-million contract with the Toronto Blue Jays, a team that has shown quite an affinity for signing players who come from prominent baseball families.

The New York Yankees are incredible. They control first place in a strong American League East division by seven games; our playoff odds project them as having an 88.3% chance of winning the division, with 16.2% odds to win the World Series. This, despite an astonishing volume of injuries suffered by key players over the first half of the season, a series of events that thrust bench bats and backups who once seemed somewhat redundant into the spotlight. DJ LeMahieu, for example, didn’t have a clear starting spot when the team signed him to a 2-year, $24 million contract over the offseason. But a week away from the All-Star break, he’s been the Yankees’ best player, and it isn’t particularly close.

At 3.6 WAR, LeMahieu is a full win better than the next-most valuable player on the roster. He leads his team in batting runs above average (20.8) and defensive runs above average (3.5). He is second in wRC+ (145) and wOBA (.389). He’s the AL’s leader in batting average (.345). The Yankees are an outstanding offensive team, ranking fourth in team wRC+ and hitting the fifth-most homers in baseball, despite the long absences of sluggers like Giancarlo Stanton, Aaron Judge, Miguel Andujar, Aaron Hicks, and Didi Gregorius. Yet, it is LeMahieu — he of the 94 career wRC+ and 61 total homers over nine seasons — who has served as the linchpin of the New York lineup.

LeMahieu has been popular around these parts for a while now. In early 2018, Travis Sawchik caught up with him to discuss his shift away from being an extreme opposite field hitter, and over this past offseason, Jeff Sullivan discussed his potential were he ever to unlock more power. This seems like a good time to check back in with LeMahieu, though, because he has spent the past few weeks setting the baseball world ablaze. Since going 3-for-5 against the Blue Jays on June 5, LeMahieu has hit .424/.467/.717, with six homers, eight walks, and 27 RBIs in 22 games. His production in that span gives him an absurd 213 wRC+ and 2.0 WAR, both of which lead the majors.

It’s been a long time since LeMahieu was this hot:

That previous spike came in August 2016, when LeMahieu rattled off a similarly torrid stretch. In 22 games from August 2-28, he hit .447/.544/.647 with four homers, 17 walks and just seven strikeouts. That happened to be his best year in the majors, as he finished with a .391 wOBA and 4.4 WAR as a member of the Colorado Rockies and won the NL batting title. Before that season, LeMahieu had always been a below average hitter; in the two seasons that followed, he was one again. Now, he’s back to being a revelation, and continues to show an ability to adapt.

One of the knocks against LeMahieu during his free agency was his predictably uncomfortable home/road splits. During his tenure with the Rockies, he recorded an OPS of .834 and a wRC+ of 96 at Coors Field, but had his OPS fall to .681 when he played on the road, with his wRC+ taking a corresponding dip to 84. That makes a good bit of sense. Because his low number of fly balls limits his power potential, LeMahieu’s offensive production relies upon him having a high BABIP, the way he did in 2016 when he hit .388 on balls in play. Coors’ spacious outfield will serve players like that well — between 2012 and 2018, three of the top four home BABIPs in baseball belonged to Rockies hitters, with LeMahieu ranking at the top of that list at .374. Away from Coors Field, his BABIP was .310. Skepticism over how valuable he could be when calling a different ballpark home was reasonable. This year, however, LeMahieu has done all he can to put that criticism to rest. At Yankee Stadium, he’s hitting a robust .335/.402/.555 with a BABIP of .357 and a wRC+ of 152 a tOPS+ of 108. His road numbers look pretty good too: .350/.375/.497, with a .385 BABIP and a 136 wRC+.

The matter of LeMahieu’s home/road splits wasn’t the only one he needed to address as a Yankee. He also needed to prove he could hit something other than a fastball. In 2018, LeMahieu was a solid fastball hitter, posting a wOBA of .356. That came honestly enough — from 2015 to 2018, only one hitter in baseball, Ben Revere, saw a higher percentage of fastballs than LeMahieu (65.8%). He struggled, however, against breaking and offspeed pitches, with wOBAs of .254 and .275 against them, respectively.

This year, opposing pitchers have begun to change the way they approach LeMahieu. Just 56% of the pitches he’s seen in 2019 have been fastballs, down 11% from a peak rate of 67% in 2017. Slider and cutter usage against him has gone up a combined 6.5% from just one year ago, and he’s seen about 2% more changeups and splitters. Added together, that’s a notable change, and in response to seeing a more balanced repertoire, LeMahieu has made himself into a more balanced hitter:

One of the keys to LeMahieu’s great 2016 season was his ability to get positive results out of just about any pitch thrown his way. With his resurgence in 2019, it’s no surprise he’s seeing similar results. LeMahieu has been one of the 10 best hitters in baseball against both the slider and the curve this year, after struggling with each of those pitches in the past. At the same time, he continues to hit fastballs well. In 2016, LeMahieu recorded a .412 wOBA against the fastball. In 2019, that number is .394. As you might imagine, striking this kind of balance isn’t easy. Across all of baseball, just two hitters have posted at least a wFB of 4.0, a wSL a 4.0, a wCB of 4.0, and a wCH of 3.0: LeMahieu, and former Rockies teammate Charlie Blackmon.

It’s easy to evaluate a recent free agent signee in the midst of an unsustainable hot streak and say a bunch of teams missed out on him. But LeMahieu makes the impulse difficult to resist. Just two teams have gotten at least LeMahieu’s 3.4 WAR out of their second basemen, and no team has gotten more value out of a position player free agent who signed this offseason:

With the return of Hicks and Judge, as well as their trade for Edwin Encarnacion, the Yankees are closer to full strength than they’ve been in a long time. But they still have a long way to go. Stanton and Cameron Maybin are likely out until at least August, while Andujar won’t return until 2020. Injuries persist on the pitching side. A deep postseason run remains very likely, but it will continue to require constant adjusting and refining for the team to reach its potential. Perhaps that makes LeMahieu the perfect player for the Yankees.

The MLB All-Star Game is just two weeks away, and the Baltimore Orioles have been campaigning hard for Trey Mancini to appear on the American League roster. This is understandable — at 22-58, the Orioles have given fans little to cheer for this year, and Mancini is rather unambiguously the best player on the club. Teammate Chris Davis has been vocal in his support for Mancini, and the organization went so far as to put together a full-fledged (if tongue-in-cheek) campaign video for him.

Baltimore’s enthusiasm surrounding Mancini’s All-Star candidacy helps draw attention to what has been a fantastic bounce-back season for the 27-year-old. He owns a .303/.362/.557 line and a 139 wRC+, good for 24th-best in the majors. His 7.9% walk rate and 19.5% strikeout rate are both career bests, and his xSLG, xBA, and xwOBA figures each put him in the 87th percentile of all major leaguers or better.

That set of numbers contrasts sharply with where we found Mancini in 2018. He smacked 24 homers for a second year in a row, but that was the lone bright spot in an otherwise underwhelming offensive season. He hit just .242/.299/.416, posting a 93 wRC+ and 0.29 BB/K figure. Because Mancini was a nightmare in the field — his -17.2 defensive runs above average were the fifth-worst in baseball — he finished the season as a sub-replacement level player. In most other organizations, he likely would have lost his starting job, but on the talent-bereft Orioles, he’s gotten a second chance. How has he made the most of it? Read the rest of this entry »

Before Peter Alonso’s otherworldly power sent him soaring through the New York Mets’ farm system and into an everyday starting job with the major league squad in 2019, the team had another well-regarded first base prospect that was expected to anchor the position for years to come. Because of a great hit tool, Dominic Smith was ranked by our Eric Longenhagen as the No. 73 prospect in baseball heading into the 2017 season. He failed to produce much as a rookie that year, posting a 75 wRC+ in 183 PA, and he only marginally improved to a 84 wRC+ in 149 PA last season. When Alonso came out of the gates mashing, the defensively limited Smith was effectively reduced to being a bench bat. With his once-rising star dwarfed and his playing time dwindling, the pressure was on Smith to prove himself quickly.

It might be a stretch to say he’s proven anything yet, but Smith has certainly recaptured some attention. In 105 PA, Smith has hit .348/.448/.562, posting a 172 wRC+ that ranks fifth-best among all major league hitters with at least 100 PA. Those numbers ought to become even more impressive when considering the fact that Smith has only started 16 of the 60 games he’s appeared in this season, making 30 appearances as a pinch hitter. His numbers in those situations are outstanding: a .318/.500/.545 slash line, with seven walks and just four strikeouts when coming off the bench.

The key to Smith’s improvement has been a cooler, more confident approach after watching his plate discipline stats completely bottom out a year ago. In 2018, Smith struck out 47 times and walked only four times, good for a 31.5% strikeout rate and 2.7% walk rate. This year, he has 20 strikeouts against 15 walks — a 19% strikeout rate and 14% walk rate. The sample size is still a tad small, but his near-9% walk rate in the minors suggests his discipline had never been in question before, and there is plenty of evidence to suggest the changes in his approach are real.

Nobody can definitively say whether the Reds will be sellers at the trade deadline this year. At 33-38 and near the bottom of the National League Central, they certainly look the part of sellers. Their Pythagorean record is quite a bit better than that, but they’re well back of the Brewers and Cubs and drifting away from the Wild Card slots. They have several guys on the roster playing out the final years of their contracts, so it wouldn’t be a surprise if they sold. If so, one of the players plenty of teams will be interested in David Hernandez.

You’d be forgiven for not grouping Hernandez with the game’s best relievers. His 4.50 ERA is below league average, and though he’s had a solid career, he’s never been one of the game’s premier late-inning arms.

However, glance past his surface numbers, and he starts to look a little better.

That’s a list of some of the most feared relievers in the game, and Hernandez’s name is right there with them. His elite FIP stems from his ability to keep the ball in the park. He’s allowed just two dingers in 32 innings, good for the 13th-best HR/9 ratio in baseball. That would be his best mark since 2012, but it isn’t far off from the 0.65 HR/9 figure he posted in 2017 or his 0.84 mark last season.

Hernandez is also generating plenty of strikeouts. His 11.8 K/9 ratio represents something of a breakout, or at least a resurgence. He was an elite strikeout pitcher back in 2012, when he punched out 98 hitters in 68 innings and posted a 2.50 ERA and a 2.08 FIP. He traded a few strikeouts for ground balls in the years following, as he struck out a still-solid 9.3/9 from 2013-18. In 2019, the strikeouts are back, and he’s again exceptional.

Do you remember when Chris Archer was really good at throwing baseballs? You should, because it was very recent! From 2014-17, only 12 pitchers across the majors accumulated more WAR than Archer. He was a strikeout maestro who kept his FIP consistently low with a knack for gobbling up innings and a sweet head of hair to boot, looking like an ace in pretty much every sense of the word.

Those days feel far away now, however, after a disastrous start on Tuesday brought his rough season with the Pittsburgh Pirates to a crescendo — he surrendered five home runs to Braves hitters in six innings, leading to an ugly seven-run outing. He has now allowed 16 homers in just 59.2 innings, giving him the fifth-highest HR/9 rate among all big leaguers with at least 50 innings pitched. His ERA of 5.79 is actually outperforming his 6.15 FIP. The old Archer seems long gone, but what caused him to vanish?

Typically, when a player regresses this swiftly and severely, there can be multiple issues to blame for their struggles. If you squint, you can see a few present with Archer. His four-seamer has lost two miles per hour in velocity over the past two seasons. He’s also throwing fewer strikes than he has in past years — something that is evident in his skyrocketing walk rate, up at 4.53/9 from a career average of 3.03/9 — but just 1.5% less than his career average. We can nitpick and analyze a million different data points to paint a picture of why Archer has lost his groove, but instead, let’s just talk about the issue right in front of us: His sinker has been absolutely dreadful.

I’ll admit his sinker has accounted for just 22% of his pitches this season, and that’s if you go by Baseball Savant’s pitch tracking. Our own Pitch Info data says he’s thrown it less than 15% of the time. How bad can a pitch be to be singled out as possibly the biggest cause of a player’s struggles if he throws it with less than one quarter of his pitches? In this case, extremely bad! In 2019, Archer’s sinker has resulted in a .370/.485/.815 slash line for opposing hitters. The Statcast data for the pitch is equally gruesome: .403 xBA, .761 xSLG, .522 xwOBA.
