Dan Petry Tackles a Challenging Career Quiz

Junfu Han-USA TODAY NETWORK via Imagn Images

Dan Petry faced 644 different batters across the 1979-1991 seasons, and while he certainly doesn’t remember them all, his level of recollection is impressive. Now 67, the former All-Star right-hander proved as much when he became the latest pitcher-turned-broadcast analyst to tackle one my a matchup-focused career quizzes. As did David Cone, Mark Grant, Mark Gubicza, and Jeff Montgomery — those pieces can be found here, here, here, and here — “Peaches” reached into his personal memory bank to take a stab at answering my questions, and to provide entertaining anecdotes while doing so. Our conversation took place at Fenway Park this past weekend.

I began by asking him which batter he faced the most times.

“It would have to be somebody in the American League East,” replied Petry, who played the bulk of his career with the Detroit Tigers and is now Dan Dickerson’s primary partner in the team’s radio booth. “I’ll say Robin Yount.”

It was indeed Yount, who stepped in against Petry 89 times. I proceeded to ask which player recorded the most hits off him.

“That might be a trick question, because maybe it is Robin Yount,” said Petry, before going with a different answer. “But I think a lot of my answers are going to be George Brett, so I’ll say George Brett.”

He should’ve trusted his initial instinct, because Yount was the answer again. The Hall of Famer logged 24 hits in 83 at-bats against the right-hander, who went 119-93 as a Tiger and 125-104 overall, while tossing 2,080 1/3 innings over 370 big league outings.

“He is a guy who I’ve always, to this day, have so much respect for,” Petry said of the Milwaukee Brewers icon. “I remember when he was just a teenager. At that time [when Yount was in the majors at age 18], I was a teenager also, and thinking about whether I would ever get that opportunity to play, like he was doing. So, just getting to face him was among my most competitive moments.”

Edwin Díaz Is Headed for Surgery, Shaking up Dodgers Bullpen

Jayne Kamin-Oncea-Imagn Images

When the Dodgers signed Edwin Díaz to a three-year, $69 million deal last December, it marked the second straight winter that they paid top dollar for a free agent closer, after they’d inked Tanner Scott to a four-year, $72 million deal in January 2025. That they double-dipped in such fashion was both a particularly ostentatious display of their purchasing power and an acknowledgement that even the best relievers can be fickle and fragile. Scott scuffled throughout last season while also missing time due to multiple injuries, and ultimately spent October as a bystander as the Dodgers cobbled together a makeshift late-game bullpen and won their second consecutive championship. Now, after struggling with his velocity and command, Díaz has also gone down with an injury. On Monday, one day after failing to retire any of the four Rockies he faced, he was placed on the 15-day injured list due to loose bodies in his right elbow. He is set to undergo arthroscopic surgery on Wednesday to have them removed.

Even in small-sample season, the 32-year-old Díaz’s numbers tell enough of a story to suggest that something is amiss. He’s allowed seven runs in six innings for a 10.50 ERA, accompanied by a 4.96 FIP and a 4.39 xERA. His 15.2% differential between his 30.3% strikeout rate and 15.2% walk rate is just over half of his 29.8% differential last year. His four-seam fastball has averaged just 95.7 mph, down from last year’s average of 97.2 mph while with the Mets, for whom he posted a 1.63 ERA and a 2.28 FIP in 66 1/3 innings. His average arm angle has dropped, changing the movement profiles of both his four-seamer and slider:

Edwin Díaz Arm Angle and Induced Movement
Season Pitch Velo Arm Angle Vert Horiz wOBA xwOBA Whiff%
2024 4-Seamer 97.5 18 13.2 13.6 ARM .276 .279 36.6%
2025 4-Seamer 97.2 17 12.9 13.1 ARM .223 .283 39.4%
2026 4-Seamer 95.7 13 12.7 10.5 ARM .564 .454 11.5%
2024 Slider 89.6 23 5.3 1.1 GLV .263 .226 39.4%
2025 Slider 89.1 22 3.8 1.7 GLV .237 .216 44.0%
2026 Slider 88.1 19 2.6 2.5 GLV .280 .245 28.1%
Source: Baseball Savant

Relative to last season, Díaz has lost over two and a half inches of horizontal run on his fastball and nearly an inch of cut on his slider, which itself is one mile per hour slower, as well. Neither pitch has fooled hitters to nearly the same degree as before, and his overall swinging strike rate has dropped from 17.3% in 2024 and 18.0% last year to 9.1% this season.

Can the 2026 Mets Be Salvaged?

Jayne Kamin-Oncea-Imagn Images

With big expectations entering the season, the New York Mets got off to a reasonably solid start; through their first 11 games, they had a 7-4 record and a half-game lead in the NL East. Since then, though, things have gone… less well. And after getting swept by the Chicago Cubs over the weekend, the team is now sitting on an 11-game losing streak, a skid that has dropped them into last place in the NL East, a full 8 1/2 games behind the Atlanta Braves. So, just how doomed are the Mets?

While you can’t win a pennant in April, you can certainly lose one. As my colleague Jay Jaffe noted last week, when the Mets’ losing streak stood at a mere eight games, the offense bears a large share of the blame. They’ve scored just 19 runs since the streak began, and have managed even three runs in just two of those games. The Royals, the next-worst offense over their last 11 games, have scored more than 50% more runs than the Mets (31 to 19), and considering they’re 2-9 over that stretch, it’s not like they’re cruising either. The loss of Juan Soto to a strained calf muscle is significant, but it’s hard to pin the team’s offensive woes solely on that. Their 1.7 runs per game is about three runs off both the 4.7 they scored last year and what ZiPS projected for this year, and no hitter in history has made that big of a difference.

Avatar Jay Jaffe: Good afternoon, and welcome to another edition of my weekly chat. I’ve got a piece about Edwin Díaz’s impending elbow surgery in the pipeline, while yesterday I wrote about Yordan Alvarez’s hot start (https://blogs.fangraphs.com/amid-houstons-problems-yordan-alvarez-is-l…).

Avatar Jay Jaffe: Last Friday, I wrote about the Mets’ losing streak (https://blogs.fangraphs.com/no-offense-the-new-look-mets-are-in-quite-…), which has now reached 11 games. It’s brutal.

21127: After you wrote about the Mets, would you have guessed another FG writer would write about the Mets before the losing streak ended?

12:05
Avatar Jay Jaffe: Hah, that is brutal. I focused my piece on the offense’s shortcomings, knowing that there would probably be room for a follow-up on their pitching or some other aspect of their struggles at some point, but I did expect them to at least win a game here or there along the way.

Justin: I don’t think Mendoza should be fired, but I’m surprised he hasn’t been. Do you think the Mets let him go? Thanks

Tyler Phillips Is at It Again

Rick Scuteri-Imagn Images

The other night, I was lying around, looking at my phone, trying to fry as many neurons as possible without using hard drugs or listening to Angine de Poitrine, and I saw something that bugged me a little. It was a highlight reel from a series of interviews with Padres closer Mason Miller and Kait Maniscalco, which started off as follows:

Maniscalco: Do you think closers have to have a couple screws loose to want to pitch in the highest-pressure situation in the game?

Miller: Quietly, yes. Outwardly, I think you can keep it together and be a fairly normal dude… I wouldn’t say anybody would say I have a screw loose quite yet.

There are two ways to read this question. First: Does it take an unusual personality type to thrive in a high-pressure environment like closing out a big league baseball game? Probably, to some extent. The ability not only to thrive under pressure but also to shake off failure when it comes is a special thing, one baseball people have tried and struggled to identify since the closer role was invented.

Munetaka Murakami, as Advertised

Peter Aiken-Imagn Images

The book on Munetaka Murakami was pretty straightforward when he hit the market this winter. Phenomenal cosmic power – itty bitty contact rate. While acknowledging recent injuries, our writeup noted his contact rates against good velocity (63%) and secondary pitches (50%) as red flags in his profile. And these weren’t little red flags, either. As Eric and James put it, “…if Murakami is only ever the quality of contact hitter we’ve seen the last three years, with no changes or improvements, he basically can’t be a good MLB hitter.”

Through a month of play, Murakami has been a very good MLB hitter, with a 153 wRC+ driven by a 21.5% walk rate and eight homers. But he’s struggled with contact, and that’s putting it mildly. He’s striking out a third of the time so far, with the fourth-lowest contact rate in baseball through Sunday’s action. So what can we say about that? One answer is that it’s too soon to say – either his contact rate will go up or his production will go down. But that’s pretty unsatisfying. To be fair, it’s probably right, but that doesn’t make it satisfying. So let’s break his game down more granularly to see where the whiffs are coming from, where the power is coming from, and how the two are related.

We’ll start with the “can’t hit secondaries” part of the scouting report. In the early going, that has been abundantly clear. Sixty-six batters have swung at 25 or more sliders this season. Murakami’s 59.3% whiff rate is the third highest, behind Max Muncy The Younger and James Wood. If you broaden that out to all secondaries, 201 batters have offered at 50 or more secondary pitches this year. Murakami’s 53.3% whiff rate is the third highest of that group, behind only Matt Wallner and Daniel Schneemann. Read the rest of this entry »

Summit League Baseball Reached an Epic Peak Over the Weekend

“I thought our story was epic, you know. You and me. Spanning years and continents. Lives ruined and blood shed. Epic.”

Over the last decade or two, internet meme-speak has watered down the word epic to a synonym of awesome, but with an exaggerated grandeur not quite captured by merely saying, “That’s awesome!” Because awesome itself has been watered down over the years, and no longer really implies something awe-inspiring, but instead something more akin to “cool.” And now, due to the fleeting nature of internet trends, the word epic is now outdated meme-speak at that, only used by cringe olds, too self-obsessed to notice that no one talks like that anymore.

But near the end of the second season of Veronica Mars, when Logan Echolls (quoted above) bemoans the way his relationship with Veronica has seemingly fizzled out, he’s using the more traditional, literary definition of epic (a little less Homer Simpson and a little more Homer’s The Iliad). Epic poems are rhythmic, lyrical narratives, known for their vast length and fantastical foes. Veronica immediately pushes back against Logan’s romanticized notion of epic love. Epic should not be an aspirational modifier for one’s love story. In general, epic narratives are pretty unpleasant for everyone with direct involvement, but they make for great television. And baseball games.

Late Saturday afternoon, the University of Northern Colorado Bears earned a walk-off win against the University of St. Thomas Tommies in a 21-inning epic at Koch Diamond in St. Paul, Minnesota. It was the longest game in Summit League history and the eighth-longest game by innings in Division I history.

But the sharp-eyed among you may have noticed a strange detail in the game’s description, aside from the general oddity of its going 21 innings. To understand how the Bears were able to win in a walk-off on the Tommies’ home field, we have to go all the way back to March, when the first bad omen befell the season series between these two teams.
