I never thought I’d get to use the transit method. If that phrase rings a bell but you can’t quite place it, let me remind you about NASA’s Kepler space telescope, which spent nine years pointed out into space, observing stars. By measuring tiny dips in the brightness of those stars, scientists were able to detect the existence of thousands upon thousands of planets that orbited them. Those exoplanets blocked out some of the light when their orbit brought them between their star and Earth, and Kepler was attuned to interpret the minuscule effect of those shadows. Anyway, this is as close as I’ll ever come.

It happened in Seattle on Wednesday, and it started in the bottom of the seventh inning. The score was knotted at three at the beginning of the frame, but the Mariners quickly broke things wide open. J.P. Crawford knocked in two runs with a single past the third baseman, then Julio Rodríguez knocked in Crawford with a double to the deepest part of the ballpark. That brought Cal Raleigh to the plate with Rodríguez, briefly, on second. In the dugout, tuckered out from his 270-foot journey, Crawford did exactly what a high-performance athlete is supposed to do. He focused on recovery.

Raleigh took a Reid Detmers curve for a ball, then another for a strike. Rodríguez took off as soon as Detmers raised his right foot for the 1-1 pitch. The slider hit the outside corner and Raleigh was out in front of it, chopping it down toward the third baseman. Or rather, toward where third baseman Luis Rengifo would have been standing were he not covering third base. The steal attempt forced him over to the bag and he watched helplessly as the world’s easiest chopper floated right toward the vacancy he’d created. But that vacancy was soon to be filled. Rodríguez bore down on the base, putting him on a collision course with the ball. Or not. Read the rest of this entry »

Particularly in light of their failure to upgrade their roster this winter, starting pitching is the foundation of the Seattle Mariners. Last year, four of their starters took at least 30 turns, and the unit posted the majors’ lowest ERA (3.38) while ranking either first or second in the American League in FIP and WAR as well. But while this year’s Mariners are currently running first in the AL West at 17-12, their rotation has scuffled, in part because it’s far from whole. George Kirby, who led the staff in WAR last year, began the season on the injured list due to shoulder inflammation, and now Logan Gilbert, who made the All-Star team and received Cy Young votes, has joined him there due to a flexor strain.

The 27-year-old Gilbert made his sixth start of the season on Friday night at T-Mobile Park against the Marlins. While the results were impressive — he needed just 29 pitches to throw three perfect innings, striking out three — his average four-seam fastball velocity was down 1.1 mph from his season average of 95.6, and his slider and curve were a bit slower than usual as well. He did not return for the fourth inning, replaced by reliever Casey Lawrence, and the Mariners soon announced that he had departed due to forearm tightness.

“I felt it a little bit warming up,” said Gilbert. “Just never really went away. Sometimes you just get going and it feels a little better. Tonight, it just didn’t.” Read the rest of this entry »

Jorge Polanco has always been a good hitter. He has a career 111 wRC+, and since he started getting regular playing time in 2016, he’s finished with a wRC+ below 100 only three times, one of which was the pandemic-shortened 2020 season. But he’s played 20 games so far this season, and he’s never had a 20-game stretch quite like this. He’s batting .377 with a 233 wRC+. How is Polanco – while injured – running the fifth-best xwOBA in baseball and second-best overall batting line?

As I mentioned, Polanco isn’t 100%. He underwent surgery in October to repair his left patellar tendon, and soreness in that knee has already cost him a couple of games this season. Polanco has also been dealing with a minor oblique strain, which has kept him from hitting right-handed since March 31. Polanco has a career 118 wRC+ as a lefty and a 95 wRC+ as a righty. That’s a legitimate platoon split, but it’s not big enough that we should have expected him to turn into Babe Ruth once he quit batting right-handed. Moreover, you have to imagine that the injury is slowing him down at least slightly, even from the left side. Maybe I’m wrong here, but it’s just hard to believe that any baseball swing could be completely unaffected by an oblique injury.

Just to recap, Polanco has a minor injury. He’s only batting left-handed and (with the exception of one plate appearance that ended with a strikeout) only facing righties. He’s also DHing and getting days off to protect the oblique. Oh, and he’s been the best hitter in baseball (non-Aaron Judge division). So let’s figure out what’s going on. We’ll start with the basics. Here are Polanco’s numbers from each of the five most recent seasons. Read the rest of this entry »

Brooks Baldwin doesn’t profile as a future star, but that doesn’t mean he won’t have a long and productive major league career. Versatility is a big reason why.
A poor man’s Ben Zobrist, the 24-year-old switch-hitter has played every defensive position besides first base, catcher, and pitcher since debuting with the Chicago White Sox last summer. It may be only a matter of time before those three are added to his résumé. Counting his days as a North Carolina prep and a UNC-Wilmington Seahawk, there isn’t anywhere he hasn’t played.

The versatility dates back to his formative years.

“I’ve been playing all over the field since I was 10 years old,” explained Baldwin, who was announced as a third baseman when the White Sox selected him in the 12th round of the 2022 draft. “It’s something my dad instilled in me, not restricting myself to one position. He played pro ball a little bit [in the Cleveland Guardians system], and before that in college at Clemson. He did the same thing.”

Chuck Baldwin’s son has seen time at first base in the minors, and the other two missing positions at the major league level are ones he’s well acquainted with. The chip off the old block caught “pretty often” in his freshman and sophomore years of high school, and pitched all four years. Primarily a starter, he had a fastball in the upper-80s as a senior.

Baldwin has been switch-hitting since he was eight or nine years old. His father’s high school coach, Linwood Hedgepeth, made the suggestion. After watching the naturally-left-handed hitter in the batting cage, the member of the North Carolina Baseball Hall of Fame told the elder Baldwin,’This kid can switch it.’” Read the rest of this entry »

Bryce Miller didn’t have an especially good start at Fenway Park on Tuesday. The Seattle Mariners right-hander allowed five hits, four walks, and four earned runs over 4 2/3 innings. He took the loss in an 8-3 Red Sox win.

Alex Bregman was responsible for much of the damage. Boston’s third baseman tagged Miller for a run-scoring double in the third inning, and he followed that up with a two-run double in the fifth. His track record against the 26-year-old hurler belied the success. Heading into the game, Bregman was 1-for-15 against Miller, the lone hit being an infield single last May.

Not surprisingly, Bregman ended up being a main focus when I spoke to Miller on Wednesday afternoon. I began our conversation by asking him which plate appearances he’s dwelled upon the most when looking back at his uneven performance the night before.

“Most of the thought has gone to the walks,” Miller replied. “I wanted to have a quick fifth inning, but after getting ahead of [Ceddanne] Rafaela 1-2, I didn’t execute a few pitches and ended up walking him. After that, I got [Jarren] Duran out on a groundball, but then I walked [Rafael] Devers. Pretty much, there went my chances of a quick inning. Read the rest of this entry »

Penn Murfee was mentioned in the interview with Trent Blank that ran here at FanGraphs on Friday. Discussing pitch profiles, Seattle’s director of pitching strategy recalled the erstwhile Mariners reliever being “a guy who had cut-ride” on his four-seam fastball.

Murfee is now with the White Sox, and Chicago’s South Side club is in Boston for a weekend series, so I took the opportunity to get his own perspective on the offering. What I learned talking to him at my home base of Fenway Park is that the movement he gets on his heater is circumstantial. Moreover, it’s legal.

“Back in 2021, in [Triple-A] Sacramento, my pitch profile changed from a running arm-side fastball,” explained Murfee, who was in the Seattle system from 2018-2023, the last year-plus of that span in the majors. “For whatever reason, I started choking the ball a little tight, and began throwing what was classified as a cutter. It went to zero inches of horizontal movement. My pitching coach at the time said, ‘Whatever you changed, don’t change it back.’ He said that I went from having a very average fastball to something unique.”

The reason behind the movement change? He stopped using sticky. Read the rest of this entry »

Welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week. There must have been something in the water across the league over the past seven days, because while this column always highlights delightful oddities that I caught, they aren’t often so delightful or so odd. This week, rarities abounded. There were runners getting hit by throws, wild acrobatics, no-look passes, and even a pitchout. Hot teams and cold teams clashed, errors got compounded, and situations that felt in hand rapidly got away. So keep an eye on the runner at first base, and let’s get started – after my customary thanks to Zach Lowe of The Ringer, who popularized this column format for basketball.

1. Not-Quite-Free Bases
Jarren Duran is off to a slow start to the 2025 season. And while the problems have mostly come at the plate, everything seems a little off. Take this misadventure on the basepaths last Thursday. Duran led off the bottom of the 10th inning with a game-tying single. That made him the winning run, and he immediately started plotting a theft of second base to get into scoring position. Nick Sandlin checked on him:

Then he checked on him again:

That’s two disengagements; Sandlin wasn’t likely to try again. Duran stole 34 bases last year. He’s blazing fast. He was 5-for-5 on the season and had already swiped one in this game. Second base was as good as his. And so the Blue Jays took extreme measures, calling for one of the least-used plays in modern baseball, a pitchout:

Trent Blank plays an integral role in one of baseball’s top pitching organizations. Now in his sixth season on the major league coaching staff, Blank is the director of pitching strategy for the Seattle Mariners. He’s well-suited for the job. The 35-year-old former minor league hurler holds an MS in Kinesiology and Exercise from Dallas Baptist University, and he previously worked at TMI Sports Medicine as a baseball performance specialist. Along with his current position, Blank has served as Seattle’s bullpen coach.

Blank sat down to talk about the Mariners’ pitching process prior to the start of the regular season.

———

David Laurila: Let’s start with a pitcher the Mariners [purchased from the Cincinnati Reds] shortly before spring training. What made Casey Legumina an attractive acquisition?

Trent Blank: “Whenever we sign anybody, we look at them through a lot of different lenses, and he popped for both our player development and analytics groups. From my perspective, we really liked some of the unique things that he does with the baseball. He has good uphill plane since he kind of changed his delivery. With his spin profile, we think we can add a couple of pitches. We’re also thinking about bringing a couple of pitches back, and repurposing them. He has a lot of raw materials we feel we can put together in a different way.”

Laurila: Can you elaborate on that?

Blank: “When we add stuff, it’s generally based on a certain spin profile we see. Then, when we talk about repurposing… with Casey in particular, it’s the sweeper. He’s had different versions of it, because he’s had different slots. We like the pitch. Adding some aggression is one thing. We’re still working through it, but the main thing is getting his fastball going at the top rail a little bit more.”

Laurila: Generally speaking, how does the organization approach introducing changes to a pitcher’s arsenal? Read the rest of this entry »

Welcome to another edition of Five Things I Liked (Or Didn’t Like) In Baseball This Week. I was at a wedding this past weekend, a generally fun event for a baseball writer. That’s because strangers ask me what I do, and then I get to say, “I’m a baseball writer.” That plays a lot better than, “I work in accounting/finance/tech,” no offense to any of you in those fine fields. But this weekend, someone inquired deeper. “Oh, like sabermetric stuff?” “Yeah! Kind of. Also I make GIFs of dumb and/or weird plays. And bunts, lots of bunts.” Yes, it’s a strange job being a baseball writer, but also a delightful one, and this week delivered whimsy and awe in equal amounts. So unlike guests milling around at a wedding, let’s get straight to the point – after the customary nod to Zach Lowe of The Ringer for the inspiration for this article format.

1. Not Reaching Home
The third time a runner was tagged out at the plate in Wednesday’s Cardinals-Pirates clash came at a pivotal moment. Locked in a scoreless tie in the bottom of the 11th, Pittsburgh finally looked like it would break through when Joey Bart singled to right. But, well:

That was a good throw by Lars Nootbaar and a clean catch by Pedro Pagés, and that combination turned a close play into a gimme. I mean, how often are you going to be safe when the catcher already has the ball in his glove and you’re here:

You lose some, and then you lose some. On Sunday at Oracle Park, the Mariners not only fell to the Giants 5-4, but they were forced to remove Victor Robles from the game after he injured his left shoulder making a remarkable catch on the game’s penultimate pitch. His injury is just one of a handful of notable ones suffered in the past several days.

Robles, who broke out last season after being released by the Nationals and signed by the Mariners, had played every inning of every game in right field until the injury. With the score tied 4-4 in the bottom of the ninth, one out, and Luis Matos on first base, Patrick Bailey fouled a drive into the right field corner. Robles sprinted 113 feet, leapt to grab the ball, and then fell over the half-height padded fence and into the netting. After extricating himself, he fell to his knees in obvious pain, rolled the ball to second baseman Ryan Bliss as Matos tagged up and reached third base, and remained on the ground. While he was tended to by Mariners head athletic trainer Kyle Torgerson, Giants manager Bob Melvin challenged the catch ruling, but the call on the field was upheld [as a reader pointed out, Matos was sent back to second under stadium boundary rules]. Finally, Robles was carted off the field, with Torgerson helping him to support his injured left arm.

Miles Mastrobuoni moved from third base to right field to replace Robles, but he didn’t need to for very long, because on the next pitch after play resumed, Wilmer Flores singled in Matos to send the Mariners to defeat, dropping them to 3-7. Medical personnel at Oracle Park popped Robles’ shoulder back into place, and after undergoing X-rays on-site, he was initially diagnosed with a dislocated left shoulder and placed on the 10-day injured list. The results of the follow-up MRI he underwent on Monday afternoon have yet to be announced. Read the rest of this entry »
