Today the Killers list turns the corner — or rather turns to the teams receiving less-than-acceptable production in the outfield corners. While still focusing on teams that meet the loose definition of contenders (Playoff Odds of at least 9.5%), and that have gotten about 0.6 WAR or less out of a position thus far — which prorates to 1.0 WAR over a full season — I have also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included them here because the team’s performance at that spot is worth a look.

As noted previously, some of these situations are more dire than others, particularly when taken in the context of the rest of their roster. I’ve batched the two corners together into one supersized roundup because three of the seven teams below the WAR cutoff for left field also make the list for right field, and because there’s plenty of crossover in play with regards to personnel. The capsules are listed in order of their left field rankings first, while noting those three crossover teams with an asterisk. As always, I don’t expect every team here to go out and track down upgrades before the July 30 deadline, but these are teams to keep an eye on. All statistics are through July 14.

Let’s start with a riddle: Team A and Team B have both played 98 games this season. Due to the vagaries of extra innings and unplayed bottoms of ninths, Team A’s pitchers have thrown four more innings than Team B’s pitchers. However, Team B’s pitchers have faced 259 more batters than Team A. How is this possible?

OK, yeah, so this was actually a pretty easy riddle. The answer is that Team B’s pitchers stink, while Team A’s pitchers are very good. Team A gets a higher percentage of batters out, which means that it faces fewer batters per inning. Let’s put some names and numbers to our hypothetical, shall we? Allow me to introduce you to the Mariners and the White Sox.

The Mariners have better pitchers and a better defense behind them. Consequently, the White Sox have allowed a whopping 130 more runs. But take a look at the last row of that table. The White Sox have thrown the most pitches in baseball, while the Mariners have thrown the second fewest. Having good pitching and good defense has allowed them to throw 1,477 fewer pitches than the South Siders. The average team throws 146 pitches per game, so we’re talking about 10 entire games’ worth of pitches. Ten games! That is a huge number, and these teams still have 64 games left to go.

Matt Strahm making the All-Star team as a setup man with no saves is a bit of an anomaly. Especially because he didn’t take the Aaron Crow route — his team had its proverbial bases covered.

The Phillies are no. 1 in baseball in pitcher WAR. They’re no. 1 by a huge margin in starter WAR, and no. 2 (a tenth of a win behind a team that has both Emmanuel Clase and 16% more bullpen innings) in reliever WAR. So it’s no surprise that Philadelphia sent five pitchers to Texas among its NL record-tying eight All-Star representatives.

The fact that Strahm is third in his own bullpen in ERA, behind Jeff Hoffman and Orion Kerkering, is mostly a testament to how good that unit has been overall. Strahm is second among relievers in FIP and tied for third in WAR. It’s not bad for a player who was an afterthought when the Phillies acquired him on the free agent market in December 2022, the same week Trea Turner and Taijuan Walker joined the organization.

Imagine an auction that takes place between three bidders. The item in question? An envelope filled with money. All three bidders employ teams of analysts that attempt to ascertain how much money is in the envelope, based on a variety of evidence that isn’t important for this analogy. Each bidder thus arrives at an estimate of the fair value of the envelope. Then they place a single sealed bid. The highest bidder out of the three gets the envelope.

What bidding strategy would you employ? Here’s a bad one: Just bid what your team of analysts calculates as the expected value of what’s in the envelope. The reason this is bad is known as the winner’s curse. If each bidder comes up with an estimate of fair value and bids that number, the winner will be the one with the highest estimate of fair value. In other words, you’ll only win if your estimation of the envelope’s value is higher than everyone else’s, and since you’re always paying exactly what you’re hoping to gain, you’ll tend to lose in the long run.

Allowing for a lot of approximation, this situation describes free agency in major league baseball. Every free agent has an unknowable amount of expected future production. Teams employ armies of analysts who attempt to estimate that production. Then, armed with that knowledge, they make contract offers to that free agent, in competition with other teams.

As I said, there’s a ton of approximation and simplification going on here. Players aren’t envelopes filled with money. Team context matters. Players don’t have to accept the highest bid. Tax regimes aren’t equal, and non-monetary incentives matter, too. Contracts are complex, and there’s no requirement that they be the same number of years, have the same number of options, no trade clauses, or anything of the sort. There’s no agreed-upon universal value system; different players present different value to different teams.

But that doesn’t mean the abstracted case has no use. As we approach the trade deadline, I think there’s one clear one: dispelling the myth that teams refuse to give up much to trade for a player who just signed a big free agent deal — after all, if they valued them enough for a blockbuster, they would have just offered a bigger contract, right? That’s a great soundbite, so you hear it all the time, but it doesn’t jive with established economic theory. Read the rest of this entry »

Strength up the middle is important to any contender, but with so many teams still in the hunt for a playoff spot, it’s no surprise some of them are have some weak spots. Sometimes it’s easier for a team to convince itself that the metrics aren’t fully capturing the strength of a light-hitting player’s defense if they’re playing a premium position, which seems to be the case with the shortstops and some of the center fielders in this year’s batch of Killers. On the flip side, occasionally it’s easier to justify shaky defense if there’s at least a hope of getting adequate offense. Then there are the times that guys get hurt and somebody has to stand out there in the middle pasture looking like they know what’s going on.

While still focusing on teams that meet the loose definition of contenders (a .500 record or Playoff Odds of at least 9.5%), and that have gotten about 0.6 WAR or less out of a position thus far — which prorates to 1.0 WAR over a full season — I have also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included them here because the team’s performance at that spot is worth a look.

One of my enduring memories of watching the All-Star game as a child — a child who became a baseball fan in a time before high-speed internet, social media, or even interleague play — was learning about all the players I’d been unable to see throughout the regular season. That included the American League and West Coast stars, but also a parade of forgettable pitchers, and yes, it always seemed to be pitchers, from crappy teams.

For some reason, Royals right-hander José Rosado is the guy who sticks out in my mind. Rookie of the Year vote-getter in his age-21 season, All-Star at 22 and 24, done in the majors at 25. If he hadn’t shown up in pregame intros between Justin Thompson and Jeff Cirillo that one time, I might never have been aware of him. Read the rest of this entry »

One of the fun things about baseball (that’s also one of the fun things about life in general) is that at any moment you can look for and find something that you alone are seeing, that you alone are paying enough attention to notice, that you alone care about. Last Wednesday, the Twins finally lost to the White Sox. The Twins had won their first eight matchups with the South Siders, and they would beat the Sox again later that day. In fact, if not for the opportunity to pummel the White Sox at frequent intervals, Minnesota’s first half would look much different and much darker. But just this once, in the first game of Wednesday’s doubleheader, the Twins lost to the White Sox.

The bird showed up sometime during the first inning. It wasn’t there when Carlos Correa slapped the 11th pitch of the game through the right side for a single, but in the bottom of the inning, when Andrew Vaughn grounded into a 5-4-3 double play and the camera whipped around the horn to follow the ball, there it was — perched on a steel cable right above the on-deck circle as if it had been there forever.

He may not be playing in Arlington tonight, but Christian Walker just wrapped up an All-Star level first half. The Diamondbacks first baseman came into the All-Star break ranked third in the National League with 22 home runs, fifth with 66 RBI, and among the top 15 qualified batters in wOBA (.357), xwOBA (.365), and wRC+ (131). His 10 OAA are third-most among NL fielders, while his 7 DRS, 4.1 UZR, and 8 FRV are all the top marks at his position. Thanks to his spectacular defensive performance, the two-time Gold Glove winner is the only qualified NL first baseman who has provided positive defensive value at first despite the hefty positional adjustment. On top of that, he has played in all 97 of Arizona’s games so far, putting him on pace for more than 700 plate appearances this season.

Add his offense, defense, and durability together and you get 2.9 WAR, which places Walker in the top 15 among NL position players and top 30 in the majors. Considering that 46 position players were invited to the Midsummer Classic this year, it’s hard to deny that Walker is having an All-Star worthy season. At the same time, it’s also hard to get too fired to up about his “snub.” Bryce Harper and Freddie Freeman have put up superior offensive numbers and WAR totals, rightfully earning the two guaranteed spots for first basemen on the NL roster. In addition, three NL players with more WAR and arguably even stronger All-Star cases than Walker were also left off the squad: Francisco Lindor, Brandon Nimmo, and Willy Adames. Finally, this isn’t even the most disappointing time Walker has missed out on a trip back to Globe Life Field within the past 10 months. Still, it’s a shame that Walker’s excellent first half will go unrewarded. At 33 years old, the late bloomer is putting together the best season of his career at the plate and in the field. Surely, that deserves to be celebrated. Read the rest of this entry »

Today, we have a two-fer of Killers lists covering a couple of key defensive positions, specifically the hot corner and behind the plate. While still focusing on teams that meet the loose definition of contenders (a .500 record or Playoff Odds of at least 9.5%), and that have gotten about 0.6 WAR or less out of a position thus far — which prorates to 1.0 WAR over a full season — I have also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. That may suggest that some of these teams will clear the bar by a significant margin, but even so, I’ve included them here because their performance at that spot thus far is worth a look.

Cubs

Following the free agent departure of Willson Contreras, last year the catching corps of Yan Gomes, Tucker Barnhart, and rookie Miguel Amaya ranked 21st in WAR. Heading into this season, it made at least some sense on paper to have the 25-year-old Amaya — a former Top 100 prospect who lost significant development time to the pandemic and November 2021 Tommy John surgery — get more playing time while moving the 37-year-old Gomes, whose framing metrics had declined, into a backup role. Unfortunately, both have been terrible. Amaya has hit just .201/.266/.288 (59 wRC+) with average-ish defense (good blocking, poor throwing) en route to -0.1 WAR. Gomes was even worse both at the plate (.154/.179/.242, 15 wRC+) and behind it (-5 DRS, -4 FRV, -3.9 FRM) before getting released on June 21, replaced by Tomás Nido, who had just been released by the Mets. Nido has hit .202/.229/.331 (57 wRC+) overall but is just 4-for-41 as a Cub. Defensively, he’s got a mixed bag of metrics, though he’s been a whisker above average framing-wise.
