Singled Out: Mariners Uncover Truth in Opening Week

Stephen Brashear-Imagn Images

The outcomes are truer than ever.

The Mariners did not record a single in their first two games of 2026. No team had ever done that in major league history. In fact, only eight teams have ever gone back-to-back games without a single, according to MLB.com’s Sarah Langs.

Mariners Box Score March 26-27
Player PA 1B 2B 3B HR K BB
Brendan Donovan 8 0 1 0 1 5 2
Cal Raleigh 8 0 0 0 0 7 1
Julio Rodríguez 8 0 0 0 0 5 1
Josh Naylor 8 0 0 0 0 0 0
Randy Arozarena 8 0 1 0 0 1 3
Luke Raley 8 0 0 0 2 3 0
Dominic Canzone 7 0 0 0 2 0 1
Cole Young 6 0 0 0 1 4 0
Leo Rivas 6 0 0 1 0 2 1
Total 67 0 2 1 6 24 9

The reason is obvious. The Mariners didn’t hit a single because they didn’t put the ball in play very often. And frankly, how could they? Guardians pitchers threw less than 40% of their pitches in the zone, and the Mariners were forced to lay off them, drawing walks in 13.6% of their plate appearances during those two games. When the Guardians did enter the zone, the Mariners struggled to make contact, striking out 35.8% of the time. That means only 34 (50.8%) of their plate appearances ended with a batted ball. And because the Mariners employ a number of sluggers, six of those batted balls flew over the fence. Read the rest of this entry »


Mariners, Top Prospect Colt Emerson Agree on $95 Million Contract

Mark J. Rebilas-Imagn Images

Apparently not wanting to be left out of the flurry of contract extensions handed out over the last two weeks, the Seattle Mariners signed a big one of their own, locking up infield prospect Colt Emerson to an eight-year contract that guarantees him $95 million over the next eight years. This includes a $1 million salary for 2026, meaning that the contract goes through the end of the 2033 season, with the Mariners holding a 2034 club option that could staple another $25 million onto the back of the contract. Emerson’s deal also includes a no-trade clause and bonuses for All-Star selections and Silver Slugger and MVP awards, de rigueur in deals such as this.

Emerson, who doesn’t turn 21 until July, is widely considered Seattle’s top prospect by most sources, whether you prefer our prospect team, Keith Law over at The Athletic, old friend Kiley McDaniel at ESPN, Baseball Prospectus, Baseball America, or mean ol’ ZiPS. That’s no small feat to pull off when you’re in the same organization that has high-end pitching arms like Ryan Sloan and Kade Anderson.

While Emerson doesn’t have one mind-blowing tool that absolutely obliterates the cognitive pathways of watchers, he’s very accomplished at basically everything he does. He’s not going to regularly blast Stantonian shots, but he’ll hit his fair share of home runs, ZiPS thinks 15-20 a year if he played home games at a neutral site rather than T-Mobile Park. Emerson is willing to draw walks, but he still retains a fundamental aggression at the plate; that’s a good thing, as being too passive is a frequent pitfall for prospects who take a good amount of free passes. There’s no whiff problem hiding in his advanced stats, either. He’s not a burner on the basepaths like Trea Turner or Bobby Witt Jr., but at the same time, he’s not me with a belly full of Cool Ranch Doritos, a 32-ounce deli container of beer, and a hamstring that hasn’t gotten a whole lot of use since the Clinton administration. It doesn’t seem like there are any serious concerns about his sticking at shortstop, and the coordinate-based method that ZiPS uses for minor leaguers sees him as a solid B+ defender at the position. Let’s crank out those projections. Read the rest of this entry »


What Do Hitters See, and When Do They See It?

Jay Biggerstaff-Imagn Images

One morning, about two weeks ago, a YouTube video made me feel like I was asleep at the wheel. Ethan Moore, a former analyst with the Rockies and the Reds, had posted a video titled “Every Baseball Analyst is Missing Something Important.” I’d like to consider myself a baseball analyst, and it sounded like I might be missing something important. And so I clicked to see what that might be.

Over the span of 36 minutes, Ethan broke down a total of three pitches, all of which were thrown by Nolan McLean to Pete Crow-Armstrong in the second inning of a late September game between the Mets and Cubs. He used this plate appearance to illustrate his central claim: There is so much happening in the handful of milliseconds between the release of the ball and the swing of a bat, and that the psychology of the hitter — conscious thoughts, subconscious expectations, muscle memories — dictates the decision of when to swing, and where, and how hard. As Ethan put it, “When the ball is in the air, on the way to the plate, what is actually happening in the mind and the subconscious brain of the hitter?”

It reminded me of another video I saw a bit earlier in the spring. It featured Vinnie Pasquantino, before he captained Team Italy in the WBC, wearing a microphone during a live batting practice session against his Royals teammate Steven Zobac. It’s meant to be a short and funny clip, and it is both of those things, but I just kept thinking about Pasquantino’s subconscious. Read the rest of this entry »


An Early, Nerdy Look At The Challenge System

Troy Taormina-Imagn Images

In the new season’s early going, the challenge system has been all the rage across the majors. If you don’t believe me, you can read ESPN’s coverage of it, or The Athletic’s, or MLB.com’s, or … well, you get the idea. The coverage has been extensive and positive, and I couldn’t agree with its enthusiasm more. I love the new system, and I’m also really excited to think about challenges in general. There are so many fun angles to consider. So here’s the math nerd’s take on what challenges have looked like so far, and what I’m most interested to learn about them moving forward.

How I’m Thinking About Challenges
Every time a strike or ball is called, there’s an opportunity for a challenge, at least so long as the relevant team has one remaining. That makes it easy to measure the prospective value of a challenge on any given pitch: It’s worth however much flipping the result of that particular pitch would change the game situation in the challenging player’s favor. All we have to do is figure out how many runs were likely to score in the inning in each case and compare the two. Read the rest of this entry »

How Long Could Joey Wiemer Have Kept Getting on Base Before You Suspected the Involvement of Shadowy Outside Forces?

Matt Marton-Imagn Images

Over the past few years, one thought has kept bouncing around in my mind: “I must be taking crazy pills.” Don’t run off to the comments to complain about this post getting political, because that’s not the point I’m trying to make. Over the past few years, longstanding institutions and norms have come crashing down without so much as a peep from the people charged with defending them. Whether you think that’s good or not, it’s a matter of historical fact.

Therefore, we live in disconcerting times. COVID, AI, mass media consolidation, man’s inhumanity to man… it messes with one’s sense of order in the universe. We’re rapidly approaching an era in which battery tech and solar power actually make electricity too cheap to meter, but NATO and the Washington Post might not exist by the time we get there.

It’s unsettling. There have been times when I’ve looked around and found that the most logical explanation is that I am, genuinely, being slipped crazy pills without my knowledge. Because surely this must make sense to someone. Read the rest of this entry »


Ponce Injury Lowlights First Starts for NPB, KBO Free Agents

Kevin Sousa, Benny Sieu, Eric Hartline, Troy Taormina-Imagn Images

Cody Ponce left his first start on a cart with a trainer.

Ponce collapsed in considerable pain Monday after making an awkward attempt to field a grounder in the third inning against the Rockies. He appeared to twist his right knee in a direction it’s not meant to go. He stood and limped to the cart on his own before exiting. Blue Jays’ manager John Schneider said after the game that Ponce will get an MRI.

The injury is an unfortunate setback for Ponce, who was making his first start in the majors since 2021. He was perhaps the most anticipated in a quartet of free agent pitchers who signed out of the KBO or NPB this winter. I’d already planned to write about each of them, leading with Ponce for the reasons he displayed before the injury. And while I don’t want to overreact to one start, I think there are interesting takeaways from each that could inform the shape of their respective seasons to come. Read the rest of this entry »

The Chase (DeLauter) Is Finally On

Stephen Brashear-Imagn Images

Chase DeLauter got an odd start to his major league career last fall — and an inauspicious one, at that — when he became the sixth player to debut in a postseason game before playing in a regular season one. The Guardians’ rookie right fielder has fared much better in the early stages of his first regular season in the majors, going on a home run binge that made a bit of history.

Facing the Mariners in Seattle on Opening Day last Thursday, the 24-year-old DeLauter started things off by homering in his first plate appearance, launching a towering 358-foot solo shot off Logan Gilbert. It was the first Cleveland run of the season, and though at least 140 players in AL/NL history have homered in their first career at-bat, in the ninth inning he joined a much more exclusive club. With the Guardians ahead 5-4, DeLauter hammered a 422-foot solo home run off Cooper Criswell, helping to seal the victory and becoming just the sixth player to homer twice in his regular season debut:

Brewers, Cooper Pratt Reportedly Agree to Extension

Dave Kallmann/USA Today Network via Imagn Images

The Brewers and shortstop prospect Cooper Pratt are reportedly close to terms on an eight-year extension. The deal would guarantee Pratt $50.75 million over the life of the deal, and there are also two club options worth about $15 million apiece. As it’s a major league contract, Pratt must be added to Milwaukee’s 40-man roster. A corresponding move to make the terms work has not yet been announced.

While extensions for prospects who have yet to debut are becoming more common, Pratt’s is a little unusual. These tend to either be large deals to consensus top prospects, often with the carrot of a ticket to the Opening Day roster as a sort of signing bonus, or smaller sums for enticing but flawed farmhands. The eight-year, $82 million extension Milwaukee inked with Jackson Chourio prior to the 2024 season is a good example of the former (as is the eight-year, $95 million pact the Mariners reportedly just struck with Colt Emerson), while the six-year, $25 million pacts Seattle signed with Evan White and Philadelphia with Scott Kingery cover the latter. Pratt’s deal doesn’t fit cleanly in either category. It’s a pretty good chunk of change for a player who evaluators generally don’t see as a future star, and it’s also not a pay-for-play deal, as Pratt will likely remain at Triple-A after signing.

Pratt was taken in the sixth round of the 2023 draft from Magnolia Heights High School in Mississippi. Eric ranked him 25th on the Draft Board that year, but his $1.35 signing bonus was commensurate with more of a second-round talent. As you’d expect for a prospect in consideration for this kind of contract, he’s performed well in pro ball. After a successful cameo on the complex in his draft season, Pratt notched a 132 wRC+ at Low-A as a 19-year-old, with strong contact skills and a low walk rate. He spent all of 2025 at Double-A, where he played a clean shortstop and hit .238/.343/.348, good for a 107 wRC+. He also dropped his strikeout rate to 15.2%, impressive for a 20-year-old at that level. Read the rest of this entry »
