While the Twins going home run-crazy in a world of home run-wackiness may have been the most significant early storyline for Minnesota, one of the team’s other early bright spots was the emergence of Martín Pérez. I was extremely skeptical of the decision to bring him in given his history with the Rangers, and thought the Twins ought to have been more aggressive in signing top free agents after clearing Joe Mauer’s salary.

In the early months of the season, my worries about Pérez seemed almost quaint. On May 23, at what I would call his high-water mark, the Twins outslugged the Angels, winning 16-7 and leaving Pérez with a 7-1 record and a 2.95 ERA. He was showing increased velocity. Pérez was never a big fastball pitcher, but his increased velocity from late 2018 — when he had an average velocity of at least 95 mph in four of his September relief appearances — continued in 2019 as a starter. But perhaps the most important factor in his early-season success was the development of his cut-fastball, a pitch he picked up on advice from his agent and with help from teammate Jake Odorizzi.

The proof of the pudding is in the eating and with his fancy new cutter, Pérez feasted on opposing batters in the late spring. Through the literal end of the season (June 20), Pérez threw 435 cutters, making it his most-used pitch, and held batters to a .164 BA and a .250 SLG. Against all other pitches, including his fastball, the league was hitting .301. 42% of his 74 strikeouts were thanks to his cutter. To put how well the cutter was performing in perspective, from 2007 on Mariano Rivera, who knows a bit about this pitch, had batters swing-and-miss on 10% of his cutters. Through mid-June, Pérez was at 15%. Read the rest of this entry »

When the Cardinals traded for Paul Goldschmidt this offseason, they added one of the most consistent and potent hitters in all of baseball to a team sorely in need of a jolt. As players go, Goldschmidt was about as safe a bet as there is. From 2013 to 2018, he had posted a wRC+ between 133 and 163 every season. His wasn’t a story of constant reinvention and tinkering: he was basically the same hitter every year. He walked a lot, struck out a lot, hit for power, and ran a high BABIP through a combination of his surprising speed and consistently above-average line drive rate.

If that’s what the Cardinals thought they were adding to the lineup with Goldschmidt, the early returns were disappointing. Fresh off of signing a five-year extension, Goldschmidt scuffled through the first months of the season. After starting off the season strong with a three-dinger game in his second game in a Cardinals uniform, he put up some alarmingly pedestrian numbers. He ran a 123 wRC+ for March and April, not up to his usual standards, and it went downhill from there. He declined to a 104 wRC+ in May and a shocking 57 wRC+ in June.

Alarmingly, it didn’t look like luck was to blame. Goldschmidt’s .302 BABIP was below his career average, but not concerningly so. His strikeouts were up a hair and his walks were down perhaps two hairs from his Arizona form, but nothing about that screamed regression. No, Goldschmidt’s problems boiled down primarily to one thing: he stopped hitting for power. In his last six seasons with the Diamondbacks, Goldschmidt had posted an ISO in the top 20 in baseball five times. The one year he didn’t, he propped up his value with a whopping 32 steals and career-best plate discipline.

With half of the 2019 season in the books, Goldschmidt’s ISO was below league average, leading to a 97 wRC+. Not just outside the top 20, not just below .200 — it was a puny .159, smack dab between Amed Rosario and Nick Ahmed. As for propping up his value with steals and plate discipline, he had zero steals and the worst K-BB% since his rookie year. Add it all up, and he’d been worth 0.7 WAR, less value than he’d accrued in his average *month* with the Diamondbacks. Read the rest of this entry »

WAR isn’t everything, and it can certainly be more variable year to year for pitchers than it is for hitters. Still, Charlie Morton — who has pitched in parts of 12 major league seasons and never before accumulated more than 3.1 WAR in a single year — has posted 4.7 WAR through 25 starts in 2019, and we’re not even all the way to the middle of August. Here’s how he compares to the league leaders in that category:

Morton, who signed as a free agent with the Rays this offseason after stints in Atlanta, Pittsburgh, Philadelphia, and Houston, has been a few different pitchers over the years. With Pittsburgh, where he established himself as a credible big league starter after a spotty minor league track record for the Braves, Morton threw two-seam fastballs nearly two thirds of the time and earned a reputation as a groundball machine, ranking 11th in the majors in GB% over the course of his seven seasons with the Pirates. In Philadelphia in 2016, and then even more markedly in Houston, where he won a world title in 2017, Morton raised his velocity by about two miles per hour across the board and added a cut fastball to complement his elite curveball.

This year for Tampa, Morton is throwing that curveball more frequently than he ever has before — 36.5% of the time, against a previous career high of 29.3% last year — and has found previously unknown levels of success in pairing that pitch with that cut fastball he first developed in Philadelphia and has been refining ever since. That pitch, in particular, has allowed Morton to make significant strides against lefties, who previously burned him to the tune of a career .344 wOBA against, but who are posting a substantially worsened .288 against him this year.

Unlike the other five divisions in the majors, the National League Central has spent 2019 in a constant state of upheaval. Four of the five teams have spent multiple days in first place, with none of the quartet being able to hang on to and solidify their lead. The division’s doormat, the rapidly collapsing Pittsburgh Pirates, spent nearly 15% of the season in first or second place. The Cincinnati Reds, the only team that hasn’t led the Central (I’m not counting the tie the morning after Opening Day), have the division’s second-best Pythagorean record.

In this environment, one might have expected to see significant wheeling-and-dealing at the trade deadline. While most of the National League could rightly claim to be in the Wild Card race, the Central teams jockeying for October baseball had the benefit of also being in a tight race for the division. Being able to draw the straight or the flush, the NL Central teams with 2019 postseason aspirations were incentivized to make an aggressive play for a Zack Greinke or a Trevor Bauer.

And the teams’ closeness wasn’t just a creation of the projections, either. On the morning of July 31, the Cubs and Cardinals were tied for first-place; the Brewers were a game back. ZiPS largely agreed that the Cubs had the strongest roster, enough to make the North Siders the favorite, but hardly a prohibitive one:

What ought to have made making significant upgrades more important for the Cardinals and Brewers is that hidden in the projections were signs that the Cubs were more dangerous at the end of July than they had been earlier in the season. Dial back to May 15 and the ZiPS projections only saw the Cubs roster as that of a .531 team, with the Brewers at .525 and the Cardinals at .519. That’s just under a two-game spread from top to bottom over the course of a 162-game season. Read the rest of this entry »

On Thursday, Jay Jaffe examined the terrible injury luck the Yankees have suffered through this season. Twenty-five players have been sent to the injured list—with 17 active stints—for a combined 1,748 days lost to injuries. Still, despite being so banged up, the Yankees are a virtual lock to make the playoffs as the American League East champion. A big reason why they’ve posted the best record in baseball is the unexpected contributions from their replacement players. The most impressive breakout has been from Gio Urshela. The 2.4 WAR he’s accumulated this year is the third highest mark on the Yankees. For a player who was seen as a glove-first utility man at one point, it’s been a remarkable transformation.

Yesterday, Urshela launched two home runs against the Blue Jays, his fourth and fifth in his last three games. That gives him nine home runs since the All-Star break, almost tripling his season total. Since the midseason break, few hitters have been as hot as Urshela. He’s posted a .380/.402/.848 slash line in the month since the All-Star game, a 221 wRC+ that ranks second in the majors. This current hot streak surpasses the good run he had to start the year.

Through the end of May, Urshela had posted a .338/.390/.482 slash line and a 131 wRC+, both excellent marks. But he accumulated just 14 extra-base hits in 154 plate appearances during that early season bender. Since the All-Star break, he has 19 extra-base hits in a little more than half the plate appearances. His isolated power has ballooned to a ridiculous .468! In the minors, the highest ISO he had ever posted was .267 in fewer than 100 plate appearances in Double-A back in 2014. He had never hit for much power until this season — and only just recently.

The other night, I was texting a friend of mine while simultaneously running one of my many queries on Baseball Savant. My “trivia” prompt was pretty simple: “Hitter with the most home runs on pitches outside the zone. Go.” His response was five words. “Javy is the obvious guess.”

Javier Báez was indeed the correct answer. The Cubs’ shortstop, who is known for his free-swinging tendency, has left the yard 28 times this season. Seven of those pitches weren’t even in the strike zone. Only seven hitters this season have at least five out-of-zone homers:

The names on this list are pretty interesting, and as you might expect, there are some similarities between them. Since Báez was the “obvious guess,” it made sense to consider whether most of these players were of a similar free-swinging variety. Generally speaking, they are. Six of the seven names on the list have an O-Swing rate above the league-average mark (31.4%), but what’s fascinating about the rest of this group is that Báez still sticks out, even if he’s not an outlier by the mathematical definition: Read the rest of this entry »
