Two weeks ago, Jay Jaffe ranked Luis Castillo fifth on his list of this season’s most improved pitchers, noting in the process Castillo’s ability to carry high strikeout rates (28.9%; eighth among NL starters) and groundball rates (55.3%; second) at the same time, thereby avoiding to some degree the harshest consequences of the major leagues’ home run boom. In this, Castillo’s third major league season, the 26-year-old Dominican has posted career-best marks in innings pitched (178 2/3), FIP (3.63), HR/9 (1.01) and the aforementioned strikeout rate. Last week, I caught up with him about the pitch he thinks has been key to his success: the changeup.

When Castillo made his debut for Cincinnati back in 2017, he threw his changeup 87-88 mph with modest break down and away to lefties and middle-in to righties. Eric Longenhagen, in ranking Castillo 10th in the Reds’ system coming into the 2017 season, rated the pitch a “below average” 40/45 but noted that it could improve with repetition, given Castillo’s arm speed and underlying talent. Each year since then has seen Castillo use the pitch more often than the season before:

Apparently the repetition has helped. In its present form, Castillo’s changeup — now with an inch more bite on each axis, thanks to mechanical changes between 2017 and 2018, while still sitting at 87-88 mph — ranks behind only Brad Keller’s as the most valuable pitch of its kind in the game (as measured by linear weights). And it’s gone a long way towards correcting one of Castillo’s obvious weaknesses coming into the season: an inability to put away left-handed hitters with anything near the same effectiveness he’s always displayed when dispatching righties (lefties put up a .373 wOBA against him last year, compared to a .256 from righties).

In the midst of what will go down as a disappointing season for the Phillies, an interesting detail about the front office’s thinking appeared. This morsel snuck into a Ken Rosenthal article: “…once the Phillies began to slump, their front office’s thinking was, ‘We don’t want to go all-out for the chance to play in the wild-card game and then face the Dodgers in the Division Series.’”

There are separate discussions to be had about whether that’s a defeatist attitude, or even whether the Phillies could have done more at the deadline. That’s for someone else to decide, though. What this statement got me, among others, wondering was: wait, would you actually rather play the Dodgers in a seven-game series than a five-game one? No one would argue that the Phillies are as good as the Dodgers — they’d clearly be underdogs no matter what. But does the extra chance of avoiding the juggernaut make up for the fact that you’re more likely to win in a shorter series?

To investigate this problem, I worked out a simplistic playoff win probability model. For each team, I took their projected rest-of-season runs scored. Then I projected a playoff rotation and how many innings each pitcher would pitch per game. Using those starters’ projected runs allowed per inning and adding in the projected runs allowed per inning by the bullpen (an admittedly inexact science that involves stripping out starters’ projections from the team’s total runs allowed projections), I was able to produce a runs allowed forecast for each starter on each team. Let’s take a look at the Phillies, for example:

Hitting a baseball comes naturally to Riley Greene. That’s not to say the fifth-overall pick in this year’s draft doesn’t work on his craft — he does— but at the same time he likes to keep any tinkering to a minimum. As the saying goes, “If it ain’t broke, don’t fix it.” Prior to the Detroit Tigers’ calling his name on June 3, Greene had been labeled “the best pure hitter in the prep class” by Baseball America.

He hit the road running in pro ball. Greene scorched the Gulf Coast League to the tune of a 1.039 OPS in nine games, quickly earning a promotion to short-season Connecticut. While not nearly as prolific against New York-Penn League pitching — a .766 OPS in 24 games — he did show enough to get moved up to low-A West Michigan in early August. Playing against much-older competition in the Midwest League, Greene slashed .219/.278/.344 in 118 plate appearances.

When I talked to the 18-year-old Oviedo, Florida native in mid-August, he made it clear that his swing is already well-established.

“My dad has been doing baseball and softball lessons for 24 or 25 years, and he taught me to hit,” said Greene. “Growing up, most of my coaches never touched my swing. It was just my dad. He’s a simple A-to-B guy, not much movement, and that’s how I try to be.”

Greene told me his front foot is his timing mechanism, and that his setup at the plate has remained essentially the same. He “might be an inch taller with his body,” but that’s a matter of feel and comfort, not because of a calculated adjustment. He’ll maybe spread out at times, but “only by a centimeter or two.” Read the rest of this entry »

Ben Lindbergh and Meg Rowley banter about Kyle Lewis’s debut, Rich Hill’s brief return, Daniel Palka’s second hit of the season, the Braves and Dallas Keuchel, and the Diamondbacks’ Brewers-style rebuild, then (18:13) talk to Will Leitch about what (if anything) Dave Dombrowski’s firing says about MLB teams’ competitive priorities, how the Cardinals (and Jack Flaherty) became the NL’s most successful second-half squad, and the NL Central and NL wild card races.

There hasn’t been much to celebrate this year in Miami, but the Marlins starting rotation has been a source of a few positive developments. Caleb Smith and Pablo López started off the season strong but faded in the second half. Zac Gallen and Jordan Yamamoto both made their major league debuts, and while Gallen was shipped out at the trade deadline, Yamamoto has shown some promise as a 23-year-old rookie. But the most exciting progress has come from Sandy Alcantara.

On the surface, Alcantara’s stat line doesn’t look that impressive. His park and league adjusted FIP sits just seven percent above league average but that’s more due to some luck in keeping the ball in the ballpark. His 18% strikeout rate is one of the worst in the majors among qualified starters despite a fastball that sits in the mid-90s. The biggest question mark attached to him as a prospect was his command of his repertoire. In his 42 major league innings prior to this year, he ran a walk rate above 15%. He’s managed to drop that down to 10.7% this year, but that’s still one of the worst walk rates in the majors.

The fourth ranked prospect in the Marlins organization and 127th overall at the start of the season, there were plenty of doubts that Alcantara could stick in a major league rotation as he developed. He’s likely going to make 30 starts this year, which has to be seen as a success for the Marlins player development group, shoddy peripherals be damned. But since the start of August, Alcantara has shown flashes of brilliance, giving Marlins fans another starting pitcher to dream on for next season.

In his seven starts since the end of July, Alcantara has posted a park and league adjusted FIP 19% better than league average. More importantly, his strikeout rate has jumped up to 22.3%, a nearly six point improvement from where it sat after the first four months of the season. The highlight of this stretch came in his last start at home against the Royals. He threw a complete game, holding Kansas City scoreless while allowing just six base runners and striking out eight. That was actually the second complete game shutout he’s thrown this year, his first coming back in May against the Mets. Read the rest of this entry »

Dallas Keuchel wasn’t supposed to still be on the market when the Winter Meetings commenced in December. He certainly wasn’t supposed to still be there as the calendar turned to 2019, and it was completely unthinkable that he would still be available at the start of Spring Training. It is only through the dark alchemy of a ghoulish lack of shame and self-awareness on the part of team owners mixing with Keuchel’s demands that he was still available after the conclusion of the Amateur Player Draft, but there he was, still waiting for a phone call from his agent, telling him a professional baseball franchise had made him a reasonable contract offer. That call finally came on June 7, when the Atlanta Braves signed Keuchel to a one-year, $13-million deal, which by that point was more of a three-and-a-half-month deal. At the very start of the free agency period, Kiley McDaniel predicted Keuchel would receive four years and $84 million on the open market. Instead, he couldn’t even secure a multi-year commitment.

Keuchel wasn’t the only player who endured this kind of unexpected wait. Former Red Sox closer Craig Kimbrel signed just one day before Keuchel, inking a three-year deal with the Chicago Cubs. Kimbrel’s season has been a disaster so far, with the 31-year-old holding a 5.68 ERA and 6.63 FIP in 19 innings. Keuchel, on the other hand, hardly missed a beat. In 16 starts after getting a late start in Atlanta, Keuchel owns an ERA of 3.35, with a FIP of 4.39 and an xFIP of 3.87. He leads the majors with a 61.5% groundball rate (min. 90 IP), with second-place Dakota Hudson well behind him at 57.2%. Of those 16 starts, 13 have ended with Keuchel surrendering three earned runs or fewer. He was pretty reliable in his first few games of the season, but after a brief blow-up in Miami of all places, he’s been totally lights-out.

In a 3.2-inning appearance against the Marlins on August 8, Keuchel allowed eight runs on 10 hits, including three homers. His ERA jumped from 3.86 to 4.83 that evening, and at the time, it seemed like it might be a sign of real danger for the 31-year-old southpaw and the rest of the Braves’ pitching staff. While his ERA had been fairly solid coming into that appearance, his 4.74 FIP was still a distressing reminder of the kind of pitcher Keuchel was, and the risk he poses. He wasn’t missing a lot of bats, with his K/9 sitting at just 6.75. Meanwhile, he had a BB/9 above 3.0 for what would have been the first time since 2012, and he was allowing a career-high HR/FB rate of 24%. Keuchel has consistently overcome low strikeout totals throughout his career thanks to excellent command, but suddenly, he was throwing strikes much less often than he used to (32% zone rate in 2019 vs. 38.6% for his career), and he was much easier to leave the yard against, even if the juiced ball has made preventing homers more difficult for everybody. That night in Miami could have altered Keuchel’s entire season, and damaged his future earning potential even further.

But that isn’t what happened. Keuchel has bounced back from getting torched in Miami to post his most dominant six-game run in years. Read the rest of this entry »

This is the second installment of this year’s Team Entropy series, my recurring look not only at the races for the remaining playoff spots but the potential for end-of-season chaos in the form of down-to-the-wire suspense and even tiebreakers. Ideally, we want more ties than the men’s department at Macy’s. If you’re new to this, please read the introduction here.

It’s been 12 days since I launched this year’s Team Entropy series, and I’m happy to report that for connoisseurs of chaos, the news is generally good, at least when it comes to the Wild Card races. The division races… eh, we’ve seen some tightening in both Centrals, but of greater significance are the pages torn off the calendar; there are but 16 days remaining in the regular season.

The Dodgers became the first team to clinch a division title this year, claiming their seventh straight NL flag on Tuesday, September 10. No other clinching is imminent, but by coincidence, the magic numbers for both East division leaders (the Yankees and Braves) and that of the AL West (the Astros) all stood at eight entering Thursday; the Yankees, with the sweep of their doubleheader against the Tigers and the Rays’ loss to the Rangers, cut theirs to five, though the other two remain at eight. It’s only a matter of time for them; there’s no reason to hold your breath in those races.

In the AL Central, the Twins — who since my last installment have lost both Michael Pineda and Byron Buxton for the season, the former to a drug suspension and the latter to shoulder surgery — have lost ground since the previous check-in. At 89-57, they now lead the Indians (86-61) by just 3 1/2 games, but with the shrinking schedule, their odds have only dropped by 0.6%, to 93.8%. The two teams face off for a three-game series this weekend in Cleveland, their last head-to-head matchup. The Indians lead the season series 9-7, and realistically probably need to sweep to keep things interesting given that they have the harder remaining schedule of the two (.487 vs. .443).

As for the NL Central, the Cardinals (82-64) have a four-game lead over both the Cubs and Brewers (78-68), each of whom has recently lost a key player for at least the remainder of the regular season, namely Javier Báez (fractured thumb) and Christian Yelich (fractured kneecap). Since reaching their season high-water mark in terms of leading the division (3 1/2 games on August 8), the Cubs are just 15-16, while the Cardinals are an NL-best 24-9 and the Brewers 18-12; the latter has won seven in a row despite the loss of the reigning NL MVP and a few other players. Since the previous Team Entropy installment, St. Louis’ odds to win the division have jumped a honkin’ 12.3%, to 76.7%, with the Cubs’ odds more than cut in half to 16.3% and the Brewers’ odds now visible to the naked eye at 7.0%. The Redbirds host the Brew Crew this weekend, and with a 9-7 series lead, need just one more win to clinch the upper hand. The odds of a season-ending tie atop the division, which would require a tiebreaker game, are at 10.1%, 0.4% higher than when we last checked in. Read the rest of this entry »

Quick: Who are the best five hitters in baseball this year? Take a quick gander at the leaderboards, if you’d like, before answering. There’s the WAR leaderboard:

That’s not what you want, though, because defense gets involved there. How about a wRC+ leaderboard instead? That should keep the Xander Bogaerts’s and Marcus Semien’s of the world from intruding on our hitting party:

Trout, Yelich, Bregman, Bellinger, and Rendon. That’s a pretty solid five. It’s also missing an obvious name: Yordan Alvarez, quite possibly the best hitter in baseball this year.

Why isn’t Alvarez on the list? It comes down to the tyranny of the qualified hitter. Setting a plate appearance minimum is a reasonable idea: without it, the best wRC+ this year would belong to Oliver Drake, who singled in his only plate appearance. No one wants that, except perhaps Oliver Drake.

That doesn’t mean that it’s always right to ignore everyone who falls short of the qualification minimum, though. Alvarez has 320 plate appearances this year, a far cry from Drake territory. Because he wasn’t called up until June, he won’t qualify for the batting title this year, but that shouldn’t distract you from the fact that he’s one of the best hitters in the major leagues, full stop.

On September 19, 2018, Carlos Santana was in the Phillies’ lineup, playing third base. It was an experiment that sparked speculation about his role in Philadelphia going forward. After all, he had just signed a three-year, $60 million contract. But after Rhys Hoskins had one of the worst defensive seasons by a left fielder this decade, it was clear that Santana’s usage would need to be adjusted. Having him play first — thus relegating Hoskins to the outfield — would not work long term, especially for a team trying to contend.

Santana’s brief stay in Philadelphia was mixed. He drew walks in 16.2% of his plate appearances, hit for power at about his then-career-average, and was about average defensively. With that information, you’d probably think that Santana had a good year, but reality was different. He was BABIP’d to death; no qualified hitter in 2018 posted a lower BABIP than Santana’s .231. His slash sat at .229/.352/.414 with a 108 wRC+, a decent-yet-unspectacular season. He also made headlines this past March when it was reported that, near the end of the 2018 season, he had smashed a clubhouse TV after witnessing his now-former teammates playing Fortnite during games.

The Phillies went on to have a memorable offseason, to say the least. They signed Bryce Harper, Andrew McCutchen, David Robertson. They traded for J.T. Realmuto and Jean Segura. Once all of the dust settled, Carlos Santana was no longer wearing red and white pinstripes. The seemingly tumultuous relationship lasted one season. Santana was back in Cleveland, the same place where he had spent the first eight seasons of his major league career. Read the rest of this entry »
