Evidently, Nicholas Castellanos doesn’t love playing in Comerica Park.

“This park is a joke,” he told Chris McCosky of The Detroit News on July 21. “It’s to the point where how are we going to be compared to the rest of the people in the league in terms of power numbers, OPS, slugging and all that stuff when we got a yard out here that’s 420 feet straight across center field?”

As we approach the July 31 trade deadline, it appears likely that Castellanos won’t have to call Comerica home for much longer. The Tigers are 30-67, and as MLB.com’s Jon Morosi reported on Wednesday, they are “virtually certain” to trade him by the deadline. But a change of scenery might not be the solution to Castellanos’ problems. Playing the majority of his games in Detroit isn’t why the outfielder has taken a slight step back this season (130 wRC+ in 2018; 114 wRC+ in 2019).

First, let’s dispense with Castellanos’ claim. Here are Castellanos’ 2019 home and road splits:

Those are some pretty drastic splits, but it’s clear that Castellanos is not being hindered by the effects of Comerica Park. The wRC+ split ⁠— which, as we know, adjusts for park factors ⁠— tells the full story. While Castellanos has been a better hitter on the road than at home, it’s not the fault of the ballpark.

In 2017, Shane Greene appeared to have turned a corner. He was coming off his first season as a near-full time reliever, one he’d finished with an ugly ERA (5.82) but a pretty nifty FIP (3.13). The latter mark, as is typically the case, proved to be the more predictive number, as he finished the 2017 season with a 2.66 ERA, though it came with a slightly higher 3.84 FIP. The following season, the wheels came off again, as he posted a 5.12 ERA and a 4.61 FIP. All told, Greene entered 2019 with a career 4.89 ERA and 4.14 FIP in five seasons split between the Yankees and the Tigers. What’s he up to now? Pretty much what you’d guess: leading all major league pitchers with an ERA of 1.06 in 34 innings.

It may seem surprising, but Greene has been around for some time now. He’s already 30, has been both a starter and a reliever for extended periods of time, and has been given a prominent role on a few lost Tigers teams over the years. Yet because of the drastic swings in his performance from year to year, we seem to know very little about him. Even if we focus solely on this year, there is still conflicting information. His ERA is obviously fantastic, but it comes with a 3.65 FIP and a 4.04 xFIP. To put the last number in context, his xFIP during his forgettable 2018 season was 4.05. Considering his contract status (he’ll be a free agent after 2020) and his role as closer for a 29-61 team, Greene is going to be a popular name in trade conversations for the rest of the month. It seems pertinent to ask, then: What exactly do we make of him?

Let’s get a few underwhelming facts about him out of the way first. His opponents’ BABIP of .179 this season is well below his career average of .304, and his strand rate is 86.1%, well above his career average of 69%. Those stats depend a lot upon luck, and 34 innings is a minuscule sample size for luck-based metrics. The fact that Greene is performing so well in them — seventh in the majors in BABIP, 32nd in LOB%, among all pitchers with at least 20 IP — gives us good reason to be suspicious of Greene’s suddenly elite ERA.

It’s easy enough to look at those measures and declare Greene as the beneficiary of unsustainable luck, and a clear candidate for regression — in fact, it’s too easy. Because while he may appear lucky at first glance, there are reasons to believe Greene really is a notably better pitcher than he’s ever been. Read the rest of this entry »

In April, Matthew Boyd gave up two homers. In May, five balls left the yard against the Tigers lefty. Last month, Boyd’s breakout season slowed as he gave up 10 homers. As we enter July, Boyd has a solid 3.57 FIP and a 3.72 ERA, and has been worth 2.6 WAR, which ranks 17th among pitchers this season. Those are good numbers to be sure, but as June began, Boyd’s ERA and FIP were both 2.85 and his 2.5 WAR ranked third for pitchers behind only Max Scherzer and Stephen Strasburg. Boyd’s strikeouts and walks have been slightly better than they were earlier in the season; his BABIP is slightly higher and his LOB% is a little bit lower. But that doesn’t explain his 5.90 ERA and 5.37 FIP. It’s the home runs that are hurting Boyd, and with the trade deadline a month away, trying to determine whether they are randomly bunching across a few starts or the beginning of a trend is an important exercise for teams looking to reinforce their rotations.

As for how Boyd broke out in the first place, the answer is a bit easier to find — the work has already been done for us. Sung-Min Kim detailed Boyd’s transformation earlier this season, showing how Boyd lowered his arm slot to gain spin on his fastball, and raised the location of the pitch. He also buried his slider more often, gained a consistency in his delivery, and basically eliminated the two-seamer. David Laurila also wrote on Boyd earlier this season, discussing his work with Driveline to create a better slider.

Boyd’s season can be carved up any number of ways depending on how you might want to use (and abuse) arbitrary endpoints. If we took away the first three spectacular Boyd starts of the season, where he struck out 29 and walked six, his FIP is 4.09, his ERA is 3.95, and he’s averaging nearly two homers every nine innings. If we look at just his first 10 starts, he’s one of the best pitchers in baseball. He has five starts with 0 or 1 runs. He’s only got two starts where his strikeouts don’t at least equal his innings pitched. The only time he walked as many as three batters, he struck out 13 Yankees. If Boyd had evenly spaced out his 17 homers across his starts, we’d be discussing a moderate breakout. Instead, we have a massive breakout followed by concern. Read the rest of this entry »

Pitchers learn and develop different pitches, and they do so at varying stages of their lives. It might be a curveball in high school, a cutter in college, or a changeup in A-ball. Sometimes the addition or refinement is a natural progression — graduating from Pitching 101 to advanced course work — and often it’s a matter of necessity. In order to get hitters out as the quality of competition improves, a pitcher needs to optimize his repertoire.

In this installment of the series, we’ll hear from three pitchers — Shelby Miller, Daniel Norris, Tyler Olson — on how they learned and developed their curveballs.

———

Shelby Miller, Texas Rangers

“I probably didn’t start throwing a curveball until high school. Growing up, my dad always told me they’re not good for your arm — not at an early age — and that changeups are better. But then there was this guy named Jerry Don Gleaton in my hometown — he played professionally, and was a baseball coach at Howard Payne University and I worked with him. He taught me some mechanical things, showed me some grips, and it kind of went from there. Read the rest of this entry »

The New York Mets made an out-of-the-box move yesterday, hiring 82-year-old Phil Regan as their interim pitching coach. The former big-league hurler, and longtime coach, takes over for Dave Eiland, who along with understudy Chuck Hernandez, was relieved of his duties in the throes of what has been an underachieving season.

As you should be aware, Regan’s nickname is “The Vulture.” It was given to him by Sandy Koufax, in a year that Regan went 14-1 out of the Dodgers bullpen with 21 saves and a 1.62 ERA. Prior to that 1966 season, he’d pitched primarily as a starter for the Detroit Tigers, the team he grew up rooting for in rural Michigan. Overall, Regan appeared in 551 games, for four teams, from 1960-1972.

The excerpted interview that follows was conducted approximately five or six years ago and was intended for inclusion in a book project — conversations with Detroit Tigers players of yesteryear — that has remained on the back burner. Given the timeliness of Regan’s hiring, I am choosing to share highlights from the interview here.

David Laurila: You were born in 1937, and grew up in southwest Michigan rooting for the Tigers.

Phil Regan: “Yes, I grew up in a town called Wayland. My earliest recollection of the Tigers was listening to Harry Heilmann call games on the radio. I recall players like George Kell, Johnny Lipon, Hoot Evers, Johnny Groth, and Vic Wertz. But my favorite of all was Hal Newhouser. He always seemed to be the one who pitched on Sundays, often against Bob Feller. He was my hero.

“During the week, I’d rush home from school, turn on the radio, and listen to Harry Heilmann and then, later on, Van Patrick. In those days we didn’t have a lot of television, but we always had the games on the radio. Of course, being from Michigan, I grew up wanting to play for the Tigers.”

Laurila: You ended up signing with them after graduating from high school.

Regan: “I did. As a kid, I never really got to play many games of baseball, because I lived out on a little farm, near a little town. Mostly I threw against a barn, with my brother, and stuff like that. But I had a good arm, and after graduating I was invited to Tiger Stadium to work out. They offered me a contract, but I decided that I wanted to go to Western Michigan [University]. After a year at Western, I decided to sign with the Tigers. From there I went into their minor league system.”

Laurila: How much did you sign for? Read the rest of this entry »

Tyson Ross has had an uneven career since being selected in the second round of the 2008 draft by the Oakland Athletics. Along with his original organization, he’s pitched for the San Diego Padres, Texas Rangers, St. Louis Cardinals, and now the Detroit Tigers. Injuries have been an issue. Currently on the 60-day Injured List with ulnar nerve neuritis, the 32-year-old right-hander previously underwent Thoracic Outlet Syndrome surgery in 2016.

When healthy, he’s been a quality big-league pitcher. Ross was an All-Star with the Padres in 2014, and the following year he led the National League in games started. His ERA over that two-season stretch was 3.03, while his K/9 was a robust 9.4. A mid-90s fastball played in a big role in that success, but it’s never been his best pitch. Ross has — when at full strength — one of the game’s best sliders.

Ross talked about his signature pitch, as well the cutter his college coach didn’t know he threw, and what he’s learned since purchasing a Rapsodo, when the Tigers visited Fenway Park in late April.

David Laurila: You’re known for your slider. What is the history behind it?

Tyson Ross: “It’s always been my go-to pitch. I went to college at Cal-Berkeley and threw a ton of sliders when I was there. But I originally learned the pitch when I was 11 years old. I was in All Stars, playing third base, and we ended up needing an emergency pitcher. I could get on the mound and throw strikes with a fastball, but I needed a second pitch. My buddy’s dad said, ‘Hey, grip it like this and throw it like a fastball.’ The second or third one broke. He didn’t actually call it a slider — he just called it a breaking ball — but it felt good in my hand, and I’ve been throwing it the same way ever since.”

Laurila: Is there anything unique about it?

Ross: “Nothing special. It just works the way it does, for whatever reason.” Read the rest of this entry »

Rhett Wiseman didn’t sign when he was drafted by the Chicago Cubs out of a Cambridge, Massachusetts high school in 2012. Instead, he attended Vanderbilt University. The reasons were twofold. Education was a priority — he’s since completed his studies and earned a business degree — and the new-at-the-time CBA had squelched any chances of his being coerced with a well-over-slot offer. As I wrote in the hours following that draft, Wiseman was viewed a second-to-fourth-round talent, and fell to the 25th round for just those reasons.

While signing was never a viable option, Wiseman did engage in dialogue with the Theo Epstein-led Cubs.

“We talked a little bit,” Wiseman told me recently. “I spoke to Theo, who I respect greatly, but just like the article you wrote at the time said, it was a situation where teams couldn’t come remotely close to the number that it would have taken to pull me away from the commitment to Vanderbilt. Looking back, I’m glad the slotting system changed in the way that it did, because it made my decision easy.”

The 24-year-old outfielder considers the three years he spent at Vandy “the experience of a lifetime,” but there were still dreams to chase. One year after being part of a team that won the 2014 College World Series, he was drafted by the Washington Nationals in the third round. This time he signed.

Pro ball has proven to be a challenge. Wiseman raked during his final collegiate season — 15 jacks and a .980 OPS — but he hasn’t come close to those numbers in the minors. There have been hot stretches, including this past April when he earned Eastern League player-of-the-month honors, but sustained success has eluded him. Even with his scalding start, he’s slashing .237/.325/.479 in the current campaign.

Wiseman knows as well as anyone that he needs to up his game if he hopes to reach the pinnacle of his profession. Baseball is, after all, a business. If you don’t perform, you’ll all too soon find yourself behind a desk, staring at a computer screen rather than at a man holding a baseball, 60 feet, six inches away.

In terms of truly understanding the ins and outs of the professional game, Wiseman might as well have been a million miles away when he turned down his first chance to sign.

“When you’re in high school, and looking at this whole process, it so isn’t what it seems,” said Wiseman. “You’re living at home and not playing every day. You have school commitments and are thinking about college. You’re still coming into full maturity. So even if you think you know what it’s like, you really don’t. It’s not until you’re in pro ball that you really understand how much of a business this is. It’s a livelihood, and it’s treated as such.” Read the rest of this entry »

Ryan Dull, Oakland A’s

“I started messing around with a slider my junior year of college. We happened to have some scouts over — it was a scout-day — and they talked to my coach about my curveball. They said I would best benefit by getting rid of it altogether, and throwing a slider. The day after that, I got together with the guy on our team who had the best slider, and started working on one. We worked on it every day.

“I actually started throwing it with a softball at first. My pitching coach in college, Aaron Rembert, had me do that. It helps give you a feel of how you get on top, and around, it. It won’t move like it would if it were a baseball, but you’ll be able to see the spin. You throw five to ten [pitches] with a softball, then take a baseball, which will give you the break you want.

Mario Impemba is part of the broadcast team in Boston now. The former TV voice of the Detroit Tigers is scheduled to work 51 regular-season games with Joe Castiglione in the Red Sox radio booth this year. The new job is different in more ways than one.

The last time Impemba did radio on a full-time basis was in 2001 when he called games for the Anaheim Angels. He did do a handful of radio games during the 2016 season — Detroit’s broadcast teams flip-flopped a few times that year — but television has long been his comfort zone. No big deal. While the mediums are different animals, the 56-year-old Detroit-area native is making a smooth segue.

“It’s kind of like riding a bike,” Impemba told me in late April. “It was seven years in Anaheim, and prior to that I did eight years in the minor leagues, so I cut my broadcasting teeth in radio. Transitioning back isn’t a big challenge. At the same time, I’m shifting abruptly after doing one medium for [17] years. It took a few games of telling myself, OK, you can’t just say ‘groundball to short; one out.’ On radio you have to describe the mechanics of the play.”

Much like the athletes making the plays being described, broadcasters have honed their skills through years and years of repetition. Be it a grounder to third or a fly to right, there is no shortage of familiarity with what’s happening between the white lines. Read the rest of this entry »
