Last Friday, Davy Andrews put Aaron Judge into context. That’s fun for the usual reasons – “Wow, look how dominant Aaron Judge is!” never gets old. But his final conclusion – Judge hits like most batters do when opponents hang a bad slider middle-middle – got me thinking. We have a pitch-level model that estimates the worst pitches. Can we use it to get an idea of what it looks like to throw a pitch so bad it turns your opponents into Judge-esque offensive producers?

There’s an easy way to sort this out. When you look at a pitcher’s player page here at FanGraphs, you can see how we model each pitch. There are a ton of scores, but I’m going to be focusing on PitchingBot today, for reasons I’ll explain shortly. The player pages break each pitch down by command and stuff. In our internal database, it’s even better: You can look at any individual pitch and get a grade on it. I set out to find the worst pitches on the year to see whether they made hitters look invincible.

Ironically, the worst pitch thrown this year made the batter look extremely vincible. Here it is in all its glory:

Another year, another frenetic trade deadline. This year’s bonanza was light on top talent relative to recent years, but it made up for that in volume. With tight races in both leagues and plenty of teams looking to shore up clear weaknesses, it was a seller’s market, particularly when it came to pitching. Now that the dust has settled, I’m here to hand out some judgment.

These are going to be inherently subjective, but that doesn’t mean I don’t put a little rigor into my system. I’m focusing on two things here when I look at individual teams. First, and more important: Did a team’s moves match up with its needs? This is easy to gauge, and since it’s the whole point of the deadline, it carries the most wait. Second: How’d teams do on the trades they made? I think this part is inherently more subjective – there’s no unified prospect ranking or database where we can see how traded players will do the rest of the season, and we’re working with less information than teams have. That doesn’t mean I’m not crediting teams for trades I like or docking them for moves I don’t, just that I’m weighting it slightly less than the first category. Let’s dive right in.

In 2022, Martín Pérez was absolutely on fire. He put up a sterling four-win season, made the American League All-Star team, and established a new career-high strikeout rate. The Rangers gave him a qualifying offer to keep him in the fold, and he accepted it. All the while, I steadfastly refused to write about him, because c’mon, really, could this be real? Surely the other shoe was going to drop, right?

It largely did. Last season saw Pérez banished to the bullpen and then used sparingly as a lefty specialist in the playoffs, where he struck out two, walked three, and gave up five runs in three outings. He signed with the Pirates after the year, and his role seemed clear: soak up innings until their exciting young pitchers were ready, and potentially continue to work with those guys in a six-man rotation thereafter. The Pirates needed bulk pitching at a reasonable rate, and he gave it to them, delivering 16 starts, 83 innings, and 0.3 wins above replacement.

Now it’s time to write about Pérez, though. Why? The Pirates didn’t have a ton of space for him given the excellence they’re getting from the rest of their rotation, so they put him on the trade block, and the most natural thing in baseball happened: AJ Preller came calling. That’s right, the Pirates traded Pérez to San Diego in exchange for Ronaldys Jimenez. The Pirates are also covering some of his salary – a sentence I’ve never actually typed before, so they’ve got that going for them. Read the rest of this entry »

Two of my favorite hobbies are getting incredibly interested in minor moves made by the Tampa Bay Rays and overrating Dylan Carlson. Boy, is today right up my alley, then: the Cardinals traded Carlson to the Rays in exchange for reliever Shawn Armstrong. Another of my favorite hobbies: teams buying and selling at the same time. The Giants got in on that by acquiring Mark Canha from the Tigers in exchange for Eric Silva. Three things I love at once? Let’s dive into the details and see what’s going on in this strange pair of trades.

It’s easy to identify the sides in the first trade. The Rays are continuing to pry apart their roster piece by piece, while the Cardinals are consolidating for a playoff push. Armstrong is a depth arm and occasional opener who can give you multiple innings at once. He’s recorded four or more outs in a game 11 times already this year, hardly your average single-inning reliever. Some of those outings have been inefficient – he has a 5.40 ERA and opponents are absolutely tattooing him when they put the ball in play. But he’s been a perfectly capable reliever for the last three years, and as we all know, single-season ERA/FIP gaps are hardly predictive. Read the rest of this entry »

Being Mets-y has been an insult for years, a description of a team combining bad execution and bad luck to snatch defeat from the jaws of victory. It’s the kind of thing that describes poor decisions but also poor circumstances. Kodai Senga spraining his calf in his first game all year and missing the remainder of the season? That’s Mets-y. Trading a huge haul to replace him and then getting nothing from the big name replacement? That’d be Mets-y too, but things have changed in Queens. Instead of splashing out prospects for Yusei Kikuchi or going after a toolsy young arm, as the Orioles did for Trevor Rogers, the Mets are doing the MLB equivalent of shopping at Costco. They acquired Paul Blackburn from the A’s in exchange for Kade Morris, their 17th-best prospect, as Will Sammon reported.

Blackburn is definitely not a name you’d put on a marquee. He’s pitched to a 4.83 ERA and 4.36 FIP in his major league career. You know how Yu Darvish is so fun because he throws seven pitches and they’re all above average? Blackburn is like that – only all of his pitches are below average. He has six different options, but our stuff models think that only his slider and cutter are even decent. He makes up for that lack of raw juice with command and with the willingness to throw any pitch in any count.

This is a trade article, as the Diamondbacks acquired Josh Bell from the Marlins today in exchange for cash considerations. It’s also an injury article, sadly. Christian Walker departed last night’s D-backs/Nationals game with an oblique injury, and was due for an MRI this morning. The results haven’t been made public yet, but trading for Bell is a statement in and of itself, so let’s walk through the trade and injury in combination.

Walker has quietly been the second-best first baseman in the game over the past three years. I don’t mean that hyperbolically; he’s second only to Freddie Freeman in WAR over that time period. He’s done it with good offense and outrageous, comically good first base defense. I don’t think I’m selling this enough. Per Statcast, Walker has been 38 outs above average over that time period. Carlos Santana is second… with 17. DRS scores it 33-20 in Walker’s favor, with Matt Olson at 21. However you look at it, Walker is head and shoulders above everyone else at the position. Last night, he made a standard-for-him, spectacular-for-most play on a foul ball:

After that inning, he came back to the dugout and departed the game. Now we and the Diamondbacks can only wait to hear the injury news. Read the rest of this entry »

I’ve been pondering Yusei Kikuchi’s trade deadline fate for months. That sounds overly specific – there are so many players that get traded every year. Why wonder about this one guy? He has a 4.75 ERA this year and a 4.72 mark for his career. He’ll be a free agent at year’s end. Months? Shouldn’t I have been doing something more useful with my time? Probably. But hey, now I’m in a better position to write about this particularly astounding deadline transaction: Last night, the Blue Jays traded Kikuchi to the Astros in exchange for a bountiful crop of young players: Jake Bloss, Joey Loperfido, and Will Wagner.

Kikuchi turns analysts like me into Fox Mulder: We want to believe. We’re talking about a guy with one of the prettiest fastballs in baseball, period. It has great shape. He throws hard, sitting 94-96 mph and topping out around 99. Stuff models love it. PitchingBot thinks it’s the nastiest fastball thrown by a starter, and tied for the overall best (with Sonny Gray’s fastball) after considering location. Stuff+ is skeptical, relatively speaking – it thinks the fastball is the third-best among starters, behind the heaters of Kutter Crawford and Zack Wheeler.

Kikuchi throws a nice slider to complement the fastball, 88-90 mph and with sharp bite for a gyro slider. He rounds out his arsenal with a hard, two-plane curveball and a bizarre slider that seems to float and fade simultaneously. He does it from a funky arm slot and with a deceptive delivery. When Kikuchi is on, he’s capable of torching opposing lineups singlehandedly. His first 10 starts of this season were phenomenal: 2.64 ERA, 2.61 FIP, a 26% strikeout rate, and a minuscule 5.5% walk rate. He’d been steadily improving in Toronto, and this year looked like his breakout.

The Mariners are 56-51 and tied for a playoff spot, so it might be hard to believe it, but their offense is bad. Not just bad for a playoff team, but 28th in baseball in runs scored bad, .300 OBP and that’s the good part of the offense bad, put Victor Robles at the top of the order because he’s the only one who’s been hitting bad. They already did a little to address that deficit by trading for Randy Arozarena, and now they’re doubling down on righty AL East bats by acquiring Justin Turner in exchange for RJ Schreck, as Ken Rosenthal and Ryan Divish reported.

Do you know who the Mariners have been playing at DH this year? It reads like a cautionary tale. Kids, if you come into the year trying to win only 54% of your games, you might give your DH at-bats to Mitch Garver, Mitch Haniger, and Jason Vosler. It’s not a lot prettier at first base. Ty France played so badly that he got DFA’d by a team desperately in search of offense. Tyler Locklear got the next shot, and he is hitting .163/.234/.326 so far. Those two lineup spots have combined for a .211/.304/.369 line, and that’s with some juice from Cal Raleigh when he gets a break from catching.

At 39, Turner isn’t the same middle-of-the-order force he was in Los Angeles. He’s settled into a savvy veteran hitter role, and started playing first base in 2023 to give the Red Sox more flexibility when he was in Boston. He’s continued to alternate between first and DH in Toronto, with a splash of emergency third base thrown in. He’s still absolutely a useful player, but he’s just not the Turner you might expect if you’ve tuned out for the last two years.

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.
