The San Diego Padres came into 2020 with one of the best late-inning setups in baseball. Their plan was simple: offseason acquisitions Drew Pomeranz and Emilio Pagán would handle high-leverage situations in the middle innings before passing the baton to Kirby Yates, one of the most dominant relievers in the game. That plan hasn’t worked out this year, largely because Yates will miss the rest of the season after surgery to remove bone chips from his elbow. On Saturday, however, they made a move to replenish their planned area of strength, acquiring Trevor Rosenthal in a trade with the Royals.

Nationals fans might wonder whether acquiring Rosenthal is supposed to be a good thing. He was, no doubt, abysmal for them last year — he racked up a 34.9% walk rate over 12 games before getting the heave-ho. A slightly longer stint with the Tigers ended the same way — striking out 28.6% of the batters you face is good, but not when you’re walking 26.8% of them as well. The Royals signed him as a reclamation project, nothing more — a minor league deal that could escalate to as much as $4.25 million based on incentive bonuses.

Consider him reclaimed. In 13.2 innings this year, he’s been effective, striking out 37.5% of his opponents en route to a 3.29 ERA that, while still short of his peak, represents a huge improvement from last year’s disaster. It’s not all daisies and lollipops, even at surface level — he’s walked 12.5% of opposing batters and given up two home runs. Mid-three ERA relievers don’t grow on trees, though, and San Diego was intent on getting one.

In acquiring Rosenthal, the Padres are making a bet that they can fix him, because despite his acceptable results this year, there are worrisome underlying signs. As Johnny Asel pointed out, Rosenthal might resemble his St. Louis form superficially, but the way he’s doing it has changed completely. He’s flooding the center of the strike zone and daring batters to hit it, which explains the better walk rate but also the hard contact.

At his peak, Rosenthal was that most cherished baseball stereotype: effectively wild. He lived on the edges of the strike zone and just outside it. That ballooned his walk rate, but it also suppressed home runs; squaring up Rosenthal’s explosive fastball and where’d-it-go changeup was simply beyond most batters when he didn’t leave them hanging over the plate.

To wit, when batters swing at pitches he leaves over the heart of the plate, per Baseball Savant’s definitions, they’ve hit nine home runs in 774 swings. When they swing at pitches on the edges of the plate, they’ve hit two in 816 swings. That’s not wildly different from how major league pitchers work in general — Rosenthal suppresses home runs in a similar ratio in both places — but for a pitcher who will always allow some traffic on the bases due to his walk rate, home runs are an anathema.

In November, teams will need to decide which minor league players to expose to other teams through the Rule 5 Draft, and which to protect from the Draft by adding them to their 40-man roster. Deciding who to expose means evaluating players, sure, but it also means considering factors like internal player redundancy, as well as other variables such as the number of option years a player has left, whether he’s making the league minimum or is deep into his arbitration years, and if there are other freely-available alternatives to a team’s current talent, which happens a lot at certain positions, like toward the bottom of bullpen barrels and with first base-only types.

Teams with both an especially high number of rostered players under contract for 2021 and many prospects who would need to be added to the 40-man in the offseason have what is often called a “40-man crunch,” “spillover,” or “churn,” meaning that the team has incentive to clear the overflow of players away via trade for something they can keep — pool space, comp picks, or typically younger players whose 40-man clocks are further from midnight — rather than do nothing, and later lose players to waivers or in the Rule 5 draft. This exercise can be done by using the RosterResource pages to examine current 40-man occupancy, subtracting pending free agents (on the payroll tab), then weighing the December ’20 Rule 5 eligible prospects to see who has the biggest crunch coming and might behave differently in the trade market because of it.

Teams seem to be getting better at preparing for this ahead of time. In my opinion, this year has fewer situations that can be leveraged by rebuilding clubs in the way, for instance, the Rangers were able to pluck Nick Solak from Tampa Bay last year. Nevertheless, here is a rundown of the (mostly) contending teams with some prospect overage that I think is worth discussing on Ops Zoom calls.

Some quick rules about 40-man rosters. Almost none of them contain exactly 40 players in-season because teams can add a player to the 40 to replace a player who’s on the 60-day injured list. In the offseason, teams don’t get extra spots for injured players and have to get down to 40, so if they want to keep some of the injury fill-ins (like Mike Tauchman of the Yankees), they have to cut someone to make room.

For the full introduction to the Replacement-Level Killers series, follow the link above, but to give you the CliffsNotes version: yes, things are different this year, and not just because the lone trade deadline falls on August 31. We’ve got a little over a month’s worth of performances to analyze (sometimes less, due to COVID-19 outbreaks), about a month still to play, and thanks to the expanded playoff field, all but six teams — the Pirates, Angels, Red Sox, Mariners, Royals, and Rangers — are within two games of a playoff spot.

While still focusing upon teams that meet the loose definition of contenders (a .500 record or Playoff Odds of at least 10%), I’ll incorporate our Depth Charts’ rest-of-season WAR projections into the equation, considering any team with a total of 0.3 WAR or less — I lowered the threshold by a point, starting with this installment, to keep these final lists from getting too overgrown — to be in the replacement-level realm (that’s 0.8 WAR over the course of 162 games, decidedly subpar). I don’t expect every team I identify to upgrade before the August 31 trade deadline, I’m not concerned with the particulars of which players they might pursue or trade away, and I may give a few teams in each batch a lightning round-type treatment, as I see their problems as less pressing given other context, such as returns from injury, contradictory defensive metrics, and bigger holes elsewhere on the roster.

Note that all individual stats in this article are through August 26, but the won-loss records and Playoff Odds include games of August 27.

This time, I’m covering third basemen and center fields, mainly so I could give a rather daunting left field herd — nine teams at 0.4 total WAR or less, and eight at 0.3 or less, when I ran the numbers on Thursday — another couple days to thin out, either by more representative performances or teams slipping below that odds threshold.

When the league announced an expanded playoff format on the eve of the season, the Blue Jays were clear beneficiaries. In the old, five-team format, we gave them just a 9.7% chance of reaching the postseason; the cream of the AL crop had a stranglehold on those spots. With eight spots and only six teams in the top tier (New York, Tampa Bay, Minnesota, Cleveland, Houston, and Oakland), however, there was more space for interlopers. The Jays’ playoff odds in the new format opened the season at 29.8%.

With roughly half the season in the books, their odds have only increased. After Wednesday’s games, the Jays looked like a clear favorite for the final spot in the playoffs:

Still, as evidenced by the fact that their odds still hover at only 65%, they don’t have anything sewn up. Their pitching, in particular, has been a weak point. Hyun Jin Ryu has been as good as advertised holding down the rotation, but you can’t make a rotation out of one pitcher. Nate Pearson has struggled in his first taste of the big leagues and is currently on the Injured List, Matt Shoemaker has a lat strain, and Trent Thornton has hardly pitched this year due to injury. Piecing together the 31 remaining games of the season looked like a challenge.

To that end, the Blue Jays brought in reinforcements today, acquiring Taijuan Walker from the Mariners. In return, they’re sending a player to be named later. Ken Rosenthal of The Athletic confirmed that the player will be outside the 60-man player pool of players eligible to be traded in-season this year, which means we won’t officially know who it is until the offseason, but the Jays have no shortage of interesting prospects.

Have we discussed the possibility of adding a second designated hitter to the lineup? Some of these offensive performances truly offend the sensibilities, just as particularly inept pitchers hitting may do. By Nichols’ Law of Catcher Defense, these guys should be the second coming of Johnny Bench or at least Ivan Rodriguez behind the plate, and yet many of them are in the red defensively — even the team with the catcher who himself is widely acknowledged as Pudge’s successor when it comes to being the game’s best defender. Also, what the hell happened to the catchers in the NL West? Somebody should be dialing Russell Martin’s number. Read the rest of this entry »

In a race for a playoff spot, every edge matters. And yet all too often, for reasons that extend beyond a player’s statistics, managers and general managers fail to make the moves that could improve their teams, allowing subpar production to fester at the risk of smothering a club’s postseason hopes. In Baseball Prospectus’ 2007 book It Ain’t Over ‘Til It’s Over, I compiled a historical All-Star squad of ignominy, identifying players at each position whose performances had dragged their teams down in tight races: the Replacement-Level Killers. I’ve revisited the concept numerous times at multiple outlets, and have presented it at FanGraphs in an expanded format since 2018.

Things are different this year, as you may have noticed. With six days to go before the August 31 deadline, just a month’s worth of performance to analyze — if, that is, a team has avoided a COVID-19 outbreak that has blown a hole in its schedule — and 23 teams within two games of spot in the expanded playoff field through Monday, putting together this year’s set of Replacement-Level Killers is a challenge like no other. The sample sizes are tiny, especially when players are sharing a position; month-long slumps are hardly unique. Even without being a complete devotee to exactitude, normally I’m able to curate a tidy list at each position by focusing on the subset of contenders (teams with .500 records or at least a 10% chance of reaching the playoffs) who have gotten less than 1.0 WAR at that spot through roughly two-thirds of the season. Scale that down to 30 games, and the threshold becomes 0.3 WAR or less, in which case a single good day by a player at the position in question might boost him from Killer to mid-pack producer.

Thus, I’m doing things a bit differently this time around. While still focusing upon teams that meet the loose definition of contenders (apologies in advance to fans of the Royals, Angels, Tigers, Red Sox, Rangers, Mariners, and Pirates), I’ll incorporate our Depth Charts rest-of-season WARs into the equation, considering any team that comes out with a total of 0.4 WAR or less to be in the replacement-level realm (that’s 1.1 WAR over the course of 162 games, decidedly subpar), though I may give a few teams in each batch a lightning round-type treatment, as I see their problems as less pressing given other contexts (returns from injury, contradictory defensive metrics, bigger holes elsewhere on the roster etc.) and I’ve pledged to keep these from becoming 3,000-word tomes.

Nothing can deflate the excitement surrounding a hopeful contender like a leaky bullpen, but as is the case most years, several teams have encountered just that kind of luck in the opening weeks of the 2020 season. At various times, the relief corps of the Cubs, Reds, and Padres have all been a hurdle for those teams to overcome, rather than an asset assisting them in their playoff pursuits. As much as those units and others have struggled this season, however, no team’s group of relievers has made victories harder to achieve than that of the Phillies. Their bullpen ERA of 8.00 is the worst in baseball by more than two runs. Unsurprisingly, that has had a big impact on Philadelphia’s postseason hopes — at 10-14, the team is last in its division, and second-worst in the National League.

Instead of packing it in, however, the Phillies have dialed up some assistance from the last place team in the other league. Late Friday night, Philadelphia struck a deal to acquire right-handed relievers Brandon Workman and Heath Hembree from the Boston Red Sox in exchange for right-hander Nick Pivetta and minor league arm Connor Seabold. Boston also sent $815,000 in cash to complete the swap, assisting the Phillies in paying the $1.05 million owed to the two relievers for the rest of the season.

Of the pair heading to Philadelphia, Workman offers the most upside. A Tommy John survivor who was still spending significant time in the minors as recently as 2018, Workman broke out in 2019 with some truly elite numbers — a 1.88 ERA, 2.46 FIP, 2.1 WAR, and 13.06 K/9. When I examined him near the end of last season, I found he’d made a number of changes to his approach. He was suddenly throwing his curve nearly half of the time, and had found a way to to dramatically reduce the number of strikes he threw without suffering a noticeable drop in opponents’ swing rate.
