Pittsburgh’s sell-off continued over the weekend, with the Pirates sending starting pitcher Jameson Taillon to the New York Yankees in return for four prospects. The 29-year-old didn’t pitch in 2020, his season lost due to rehabilitation from Tommy John surgery in late 2019, the second such surgery of his career. Taillon, a former 2010 first-round pick, has suffered more than his share of setbacks, missing three years of his career and most of a fourth due to his elbow injuries and a sports hernia; he also missed time in 2017 due to testicular cancer. He heads to a Yankees rotation with a lot of interesting upside talent and a surplus of question marks.

Taillon’s departure to join former teammate Gerrit Cole in the Bronx represents the end of an era in Pittsburgh. Taken in consecutive drafts in 2010 and ’11, Taillon and Cole were frequently imagined together as the two aces at the top of a future Pirates rotation. For a team that had had recent first-round busts in the quickly injured Brad Lincoln and the bafflingly selected Daniel Moskos, this pair was the cornerstone of the rebuilding efforts of the then-new Frank Coonelly/Neal Huntington regime. Both pitchers were consensus elite choices in the draft and were selected without any of the team’s trademark cynical calculations about whether a player would sign on the cheap.

Taillon and Cole met their lofty expectations as they quickly worked their way through the minors. Cole, a college draftee, made his 2011 major league debut just two years after draft day, and if not for injury, Taillon would have likely followed him early in 2014. Missing two years is an enormous setback for any prospect, but the Pirates averaged 93 wins per season over 2013-15 and could afford to be patient. As the holes the team had to fill in order to continue winning increased, ownership’s commitment to investing in the roster did not, and the Pirates needed Taillon in 2016 more than they did in ’14 or ’15. And he succeeded, requiring only a 10-game tuneup at Triple-A before debuting in the majors and pitching well enough where he would have gotten some Rookie of the Year votes if he had been up for the entire year.

It’s become a common narrative in baseball recently: the veteran player, struggling to secure a job in America, heads overseas to play in Japan or Korea. They spend some time there, rediscover or reinvent part of their game, and return to America to find much greater success in the majors than before. Anthony Bass made his way to Japan in 2016 after toiling away for five years on three different teams. In his one season in Nippon Professional Baseball, he played for the Hokkaido Nippon-Ham Fighters during their championship season. He ended up pitching in five of the six games in the Japan Series that year and was the winning pitcher in the championship clinching Game 6.

After getting a taste of winning in Asia’s highest league, he returned to the States in 2017 but continued to struggle to earn a regular job in the majors until latching on with the Mariners in May of 2019. By the end of the season, he had worked his way into high-leverage innings for Seattle. He was claimed on waivers by the Blue Jays after the season and continued to work as a late-inning reliever in 2020. On Friday, he signed the first multi-year contract of his career, a two-year deal with the Marlins worth a guaranteed $5 million with a club option for 2023. The 33-year-old has taken the journeyman moniker to it’s extreme but finally found a school to call home in Miami.

The success he found in Japan gave Bass a huge boost of confidence. Getting over that mental hurdle was a significant step toward realizing his talent on the field. In an interview from February of last year, he recounted that mental process to Kaitlyn McGrath of The Athletic:

“Cause I was having success there and I was like, ‘I can do it. I can come back to the States and do exactly what I’m doing here in the States and have success. When I really started telling myself I’m a really good pitcher, and just attack the strike zone with everything I have, a switch turned on in my head and it just completely changed my career from pitching almost passively and a little timid, trying to stay in the major leagues versus, ‘No, I can do this and I want to dominate at this level.”

When the Padres traded for Jurickson Profar before the 2020 season, they had a hole at second base. By the time the season started (give or take a week), Jake Cronenworth had filled that hole. But luckily for the Padres, Profar was flexible. He played the outfield for the majority of the season, more than doubling his career innings played total on the grass, and backed Cronenworth up at second while putting together the best batting line of his career. In a shortened season with heightened injury problems, his flexibility was exactly what the team needed.

On Friday, the Padres and Profar agreed to reunite, with San Diego signing him to a three-year, $21 million deal that includes opt outs after each of the first two seasons. But while Profar is headed back to southern California, what role he’ll play there remains undecided. A Padres team without many holes has spent the offseason filling in what cracks it has, leaving precious little space for more cooks in the kitchen — or so it seems.

One of the greatest unknowns facing NL teams is the DH rule. Will it come back next season? Opinions vary, and whether you can give an extra player at-bats changes roster construction significantly. The pre-Profar Friars straddled the gap between building for an extra hitter and for traditional rules. Ha-seong Kim, their prize position player signing this offseason, currently profiles as a super-utility player who starts on the bench. He could fill the DH position, but using a middle infielder (Kim is a shortstop by trade) there feels wasteful. Meanwhile, the team’s two corner outfielders, Tommy Pham and Wil Myers, are both mixed in the field. Either of them could slide to DH — Pham played DH during his tenure in Tampa — if the team could find a suitable defensive replacement. Read the rest of this entry »

Sunday, the Pirates traded starter Jameson Taillon to the Yankees for a package of four prospects. Dan Szymborksi will provide in-depth analysis of the deal as it pertains to the Yankees soon, though I’ll note to start that with the return of Luis Severino and Domingo Germán and the additions of Corey Kluber and now Taillon, the Yankees rotation will be reliant on several high-risk, high-reward starters this season.

Of course, nobody likes trading away good big leaguers, especially those who the club and city care about for reasons beyond their on-field performance. Taillon has persevered through a lot, including testicular cancer and an August 2019 Tommy John, the second such surgery of his career. When he next steps on a big league mound, it will have been nearly two years since he last did so. That layoff (he has been throwing live BP to hitters since late last summer and has been throwing bullpens during the offseason) creates volatility that mirrors the added volatility of this particular prospect package. Taillon could be an anchor of the Yankees rotation next year or might be a shell of himself. Regardless of which he would have been in Pittsburgh, the Pirates are not ready to compete and so I think they did well to trade him for four good prospects today, acquiring upside but also mitigating risk by getting several players in return.

On to those prospects. The quartet heading back to Pittsburgh — righties Miguel Yajure (age 22) and Roansy Contreras (21), 21-year-old outfielder Canaan Smith-Njigba, and 18-year-old shortstop Maikol Escotto — is a pretty exciting. Read the rest of this entry »

Mitch Keller has only thrown 69-and-a-third big-league innings, and he’s already had a remarkable career. The baseball gods are a big reason why. In his 2019 rookie season, the now-24-year-old Pittsburgh Pirates right-hander had a 7.13 ERA to go with a 3.19 FIP, and this past season he had a 2.91 ERA to go with a 6.75 FIP.

Hello, BABIP.

In an almost-inexplicable quirk of fate, Keller followed up a .475 BABIP — the highest one-season mark in MLB history — with a .104 BABIP in 2020. No pitcher who threw 20-or-more innings in last year’s pandemic-truncated campaign had a smaller percentage of balls put in play against him fall safely to the turf. This happened with an average exit velocity of 88.5 mph, which was higher than the 87.6 he’d allowed in 2019.

Ben Lindbergh wrote about Keller’s snake-bit season for The Ringer last spring, and the conversation they had prior to publication is what brought the data to the fore.

“I remember getting off that phone call and looking it up myself,” said Keller. “I was like, ‘Oh, my goodness. That’s crazy.’ I knew that I had a high BABIP, but I had no idea it was the highest in history. Once he told me, it wasn’t like I was coming back to the dugout thinking, ‘Man, I think I’m having some bad luck.’ It was actually on paper, as a stat. It was, ‘No, seriously. I was having bad luck.” Read the rest of this entry »

Ben Lindbergh and Meg Rowley reflect on the on-field feats, statistical records, and larger legacy of baseball icon Henry Louis “Hank” Aaron, who died on Friday at age 86. Then (25:47) they talk to Joe Lowry of Prospects Live about the ongoing boom in baseball cards, touching on why 2020 fueled a surge in sports-card collecting, how baseball cards have changed since the ’80s and ’90s, the finer points of breaking, box wars, and prospect cards, the demographics of current card collectors, digital cards, how to get back into baseball cards after a hiatus from the hobby, and more.

In the 2021 ZiPS projections that are live on this very website, Lucas Giolito is projected with the most WAR of any pitcher in baseball. If my social media is any indication, this projection is, so far at least, the source for the most joy and the most consternation. What is it about Chicago’s young ace that gives him such an aggressively optimistic projection?

One of the common complaints you see from readers about projections is that they don’t go out on a limb very often. To me, this makes perfect sense: when talking about the mean projections, massive performance changes should rarely be the player’s typical expectation. Think back on José Bautista back in 2010. At the time, Joey Bats was a player pushing 30 who had hit .238/.329/.400 in the majors in more than 2,000 plate appearances for five major league teams. As we now know, his destiny was to explode on the scene, slugging .617 for the Blue Jays, resulting in the first of his eventual six All-Star appearances. But that doesn’t mean that his baseline projection going into 2010 should have reflected that result; that unlikely things happen doesn’t mean that they weren’t unlikely.

Projections do go out on a limb, but in a conservative sort of way. One of the more notable examples in recent years is the 2019 ZiPS projection for Shane Bieber. With a 4.55 career ERA (but a 3.23 FIP!) in just 114 2/3 major league innings entering the season, ZiPS gave Bieber an optimistic projection as the 14th most valuable pitcher in baseball with a 3.71 ERA over 187 innings for 3.8 WAR. That was enough to put him just behind Clayton Kershaw and ahead of notables such as Zack Greinke, Noah Syndergaard, Stephen Strasburg, and Patrick Corbin. Not only did Bieber meet this projection, but he also exceeded it, finishing eighth in WAR among pitchers at 5.6.

But why did ZiPS love the Beebs so much? It wasn’t one factor. Instead, it was an accumulation of smaller positive factors that significantly outnumbered the negative ones. Bieber was only 24. He had a record in the minors and majors that suggested he could avoid lofty gopher ball totals. His BABIP in his rookie year was extremely high. From his quality-of-contact data, ZiPS thought that batters “should have” hit .252 and slugged .415 against him in 2018 when the actual numbers were .285 and .467. And so on.

It’s the same thing for Giolito entering the 2021 season. No, he isn’t in the same position as Bieber was entering 2019, given that he’s already received Cy Young votes in two seasons. But it does take something special to get ranked No. 1 with a bullet. His top-notch projection doesn’t mean that it’s going to happen, only that it’s more likely to occur than the downside scenarios. And the latter do exist: ZiPS projects a 15% chance that Giolito will be worse than a league-average starter and about a 7% chance he’ll have an ERA on the wrong side of five, both things that would have a very negative effect on Chicago’s 2021 fate.

So what are some of the reasons for this digital love?

Lucas Giolito is Still Relatively Young

Pitchers don’t have a typical age curve, but it’s still preferable to be in your twenties than in your thirties. Like Bieber, the height of Giolito’s ceiling remains an unknown. Both Gerrit Cole and Jacob deGrom are amazing pitchers, but after a few more years in the majors, there’s less uncertainty about their remaining upside. Superstars in their mid-20s, on the other hand, frequently have another gear or two remaining. Among Giolito’s top comparables were a multitude of youngish pitchers who were already stars and did have such performance bumps remaining: Greg Maddux, Jose Rijo, Dave Stieb, Brandon Webb, and so on.

Of the top 50 most comparable pitchers in Giolito’s cohort, 32 of them beat their baseline performance estimates over the following three seasons — an astounding rate of success given how attrition claims pitchers. For Cole, that number is only 23; for deGrom, 26; and for Max Scherzer, 19.

Lucas Giolito is Well-Suited for his Home Park

Home run rates for pitchers are volatile, but they’re not random. Giolito fares well in velocity and barrel-based numbers and was in the top-tier in most of these measures in 2020. Among the pitchers projected in the top 10 overall in ZiPS, only Luis Castillo consistently beat him. And this is especially important because of the characteristics of the park. Guaranteed Rate Field (that name still makes me cringe) is a bit of an unusual bird, a homer-friendly park that tends to be neutral overall. For a pitcher with an elite ability to avoid batters crushing his pitches, this provides an opportunity to squeeze out a little more value. In other words, while Guaranteed Rate is a neutral park for everyone, Giolito’s homer-avoiding tendency makes it a de facto pitchers’ park for him. This one of the reasons ZiPS liked Dallas Keuchel’s chances at a bounceback season in 2020 and continues to think he’ll be very productive for the Sox. Were this a neutral park, Giolito would lose just enough in his projection to drop him to third in the league in WAR.

Lucas Giolito Left Some Strikeouts on the Table

At a 33.7% strikeout rate, Giolito certainly wasn’t struggling to punch out batters. But from the across-the-board improvement in his contact numbers in 2020, ZiPS thinks that he should have seen a larger bump in his strikeout rate from 2019’s 32.3% rate.

As part of its model for calculating baseline expectations, ZiPS has a measurement that I’ve dubbed zSO. (The Z stands for ZiPS, as you may have guessed.) Using contact data, velocity numbers, and the like, ZiPS makes an estimate from how many strikeouts a pitcher “should” have ended up with. It’s not a number I pulled out of my hat but one used as part of the model because it has more predictive value than actual strikeouts. Going back to 2002, if all you knew about a pitcher was his strikeout rate and his zSO rate, you’d have predicted the following year’s strikeout rate most accurately with a mix that was 82% zSO and 18% actual.

Looking at the top 15, while zSO is far from infallible — all models are wrong, but some are useful — it had a solid record at identifying the strikeout outliers correctly. So what about the 2020 season? There’s a lower minimum batters faced here (200 batters faced) because of the short season, so you’ll see some larger-than-typical variations between actual strikeout rate and zSO.

No, Giolito doesn’t make the top 15 of underachievers, but he’s close. Compared to his 33.7% strikeout rate, ZiPS thought he “should have” been at 35.7. And that’s unusual, as leaders in anything in baseball are more likely to have overachieved than underachieved. Of the top 20 strikeout pitchers in 2020, ZiPS thinks that only four pitchers actually underachieved: deGrom (0.2%), Tyler Mahle (0.3%), Castillo (0.6%), and Giolito (2.0%).

In summation, ZiPS sees Giolito as a nearly perfect storm of awesomeness and one of the top Cy Young contenders in the American League. With Cleveland reeling, the White Sox have an excellent shot at taking the division and going deep into the playoffs. If the White Sox raise a world championship banner in 2021, the right arm of Giolito will likely be responsible for a great deal of the hoisting.
