Taijuan Walker Talks Pitching

Taijuan Walker came back strong in 2020. Coming off two seasons lost to Tommy John surgery, the 28-year-old right-hander put up a 2.70 ERA over 51-and-a-third innings. Six of his 11 starts came with the Toronto Blue Jays, who acquired Walker from the Seattle Mariners at the tail end of August in exchange for Alberto Rodriguez.

A return to health wasn’t the only thing that buoyed Walker’s rebound. Like many modern-day hurlers, the 43rd-overall pick in the 2010 draft has become an adherent of analytics and data-driven pitch-design. Currently a free agent, Walker is looking to move forward with a team that embraces those very things.

———

David Laurila: What is your background with analytics and pitch design?

Taijuan Walker: “I went to Driveline about a week after the 2019 season ended. I spent a few days there and got assessed — all of the numbers, threw a bullpen — and it was nice to see where I was at with my fastball spin rate, and more. We talked about the numbers, and how to use those numbers to know what I’m looking for.

“That was part of the reason I signed with the Mariners [in February]; they had a lot of that same technology. Woody [Pete Woodworth], the pitching coach there, is smart, and really good.”

Laurila: I assume you’d been exposed to analytics previously?

Walker: “Yes, but I had a chance to really learn the numbers, whereas before it was more like, ‘Hey, these are your numbers,’ but never really having them explained to me. It was never, ‘This is what they mean, and this is how to make [a pitch] better.’”

Martín Pérez Dons the Red Sox Again

The Red Sox didn’t have much to write home about in 2020, skidding to a 24–36 record and a fifth-place finish in the AL East. Though they have yet to make a major splash thus far this winter, they did make a move on Saturday, re-signing southpaw Martín Pérez to a one-year deal that constitutes a pay cut and opens questions about a rotation that was the majors’ worst in 2020.

Pérez, who turns 30 on April 4, joined the Red Sox after an uneven 2019 spent with the Twins, during which he was very good in the first half and nearly useless in the second. He was the only Boston pitcher to make more than nine starts last season, and, well, the results weren’t stellar, as he once again faded late in the year. He did start 12 times, tied for fifth in the majors, and his 4.50 ERA in 62 innings was actually a bit better than league average (97 ERA-) despite a 5.58 ERA over his final six starts. His 4.88 FIP, though, was a significant step down from league average (111 FIP-); his 17.6% strikeout rate was only a bit off his career-high 18.6% in 2019, but his 10.7% walk rate was a career worst. All told, his season was worth 0.4 WAR, which prorates to about 1.0 over a full campaign. Pérez had been worth more in five of his previous seven seasons in Texas and Minnesota, so there’s no mistaking this for being the top of his game.

What was interesting about Pérez’s performance — and I admit I may be stretching the definition of “interesting” — was that he posted the lowest groundball rate of his career. His 38.5% rate was 12 points below his previous career mark and 9.5 below  his 2019 mark; eyeballing our season stat grid, I found only half a dozen bigger drops over the past decade, though 62 innings doesn’t tell us as much as a full-season workload. Anyway, Fenway Park isn’t a great place to start serving up fly balls, but Pérez’s 1.16 homers per nine was his lowest mark since 2017, and he had no real difference between home and road splits, which may tell you a bit about the East Coast ballparks in which he toiled.

Since Pérez is going back to Fenway, the fly balls do rate as a concern, but his Statcast numbers do show that he’s done a good job of limiting hard contact since ditching his slider in favor of his cutter in 2019. In 2020, his 29.2% hard-hit rate ranked in the majors’ 90th percentile, and his average exit velocity of 86.3 mph was in the 85th percentile, versus 96th for the former and 93rd for the latter the year before. Before that, he’d never been better than middling in either category, and sometimes bad enough to slip into the bottom quartile.

Pérez threw the cutter 30.8% of the time in 2019 and 32% in ’20, and he’s gotten good results with the pitch. When batters have made contact with his cutter in that span, they’ve produced the majors’ second-lowest exit velocity and xwOBA:

While Pérez got fewer grounders via the cutter in 2020 (34%) than 2019 (44%), that alone doesn’t compensate for his shifting profile. He also dialed back his sinker usage from 24.8% to 17.7% and compensated with his curve and changeup. That cost him some grounders, and he also got fewer grounders this past year via his four-seam fastball — a drop from 40% to 19% — while doing a much better job of keeping those pitches out of the center of the strike zone:

Thanks to the better location, batters went from hitting .370 and slugging .740 when they connected with Pérez’s four-seamer in 2019 to .233 and .533 in ’20, respectively — and he did that despite the average velocity on that pitch dropping from 94.2 mph to 92.2.

Still, it was an unremarkable season all told for Pérez, and effectively, he’s taking a small pay cut after making $6 million in 2020 and then accepting a $500,000 buyout after having his $6.85 million club option declined. He’ll get a $4.5 million base salary for 2021, with additional boosts of $100,000 for passing the 130-, 140-, 150-, 160-, and 170-inning thresholds. Those same thresholds also add $100,000 apiece to his $6 million club option for 2021, while reaching 180 innings adds another $250,000, meaning that he could max out with a $6.75 million option.

While Pérez is a solid choice to provide stability at the back of a rotation, the real question is how much closer to the front of the Red Sox rotation he’ll be in 2021. Between the departure of Rick Porcello via free agency, the inclusion of David Price in the Mookie Betts trade, and the subsequent losses of Chris Sale to Tommy John surgery and Eduardo Rodriguez to COVID-19-related myocarditis, the Sox had just one rotation holdover from 2019 to ’20: Nathan Eovaldi, who was limited to nine starts by a right calf strain. As a result, the team was forced to call upon the likes of rookies Tanner Houck and Chris Mazza, veterans Colten Brewer, Zack Godley, Nick Pivetta, and Ryan Weber, and assorted openers to round out their starting five. The results were dismal: The unit’s 5.34 ERA ranked 25th in the majors; its 5.50 ERA 29th; and its 0.4 WAR dead last.

The plan is to have Eovaldi — who hasn’t made more than 21 starts in a season since 2015 — and Rodriguez in the rotation to start 2021. Sale, who went under the knife last March, will hopefully be back by midseason, as the team is taking a conservative approach with his rehab. The Sox are still in the market for a mid-rotation upgrade, with the Boston Globe’s Alex Speier listing names such as Rich Hill, Jake Odorizzi, James Paxton, José Quintana, and Masahiro Tanaka among the potential targets. Unless they land one of them, then Houck, Pivetta, and the recently signed Matt Andriese will be in the mix to fill the other two spots at the start of the season. Prospects Bryan Mata and Connor Seabold, who have 18 starts between them at Double-A and nothing higher than that yet, could be in play for later in the year. Most of those pitchers may be better fits in the bullpen than the rotation, but if the Red Sox aren’t pushing to compete, now is the time to find out what they’ve got. Meanwhile, chief baseball officer Chaim Bloom is reportedly considering the possibility of a six-man rotation given the increased workloads his starters will face. Besides Sale and Rodriguez, none of the other pitchers currently on the roster threw more than 135 innings in 2019.

All of which is to say that amid so many question marks, Pérez brings the Red Sox a bit of certainty if not a great deal of upside. He’ll eat innings in what isn’t likely to be the most memorable Red Sox season of the millennium. If he’s good enough, he might pitch himself onto a contending club down the stretch.


Yankees Raise Ceiling With Corey Kluber

The Yankees’ big free agent signing last week came when the team brought back DJ LeMahieu for six years and $90 million. That deal raises both the floor and the ceiling in the Bronx next season. LeMahieu is a dependable player who should be average at a minimum, ensuring the infield doesn’t have a black hole, while a repeat of his performance since the beginning of 2019 would elevate the Yankees’ chances of a great season. The Yankees’ other signing last week came late Friday in the form of Corey Kluber. Kluber does less to shore up the Yankees’ floor given his recent injury history; indeed, there’s a non-zero chance Kluber doesn’t contribute much to the Yankees at all this year. What Kluber and his two Cy Young awards do manage to do is substantially raise the Yankees’ ceiling, as the team should face a tough battle in the AL East.

Jeff Passan was first with the news that Kluber would be signing with the Yankees for one year and $11 million. Kluber’s contract sits between my $9 million prediction and the $12 million median crowdsource estimate from our top 50 free agent ranking. Despite making just eight starts over the past two seasons, including just a single inning last year, a couple factors worked in Kluber’s favor in securing a decent pillow contract. The first is that Kluber threw for scouts and impressed. The second relates more specifically to the Yankees.

Sunday Notes: Chris Perez Had Two PAs (He’s Bitter About One of Them)

Chris Perez didn’t get many opportunities to swing the bat during his seven big-league seasons. As a short reliever who played primarily in the American League, that was to be expected. Somewhat less expected was what happened when he did have a chance to dig into the batters box.

“I had two [plate appearances], and I’m bitter about one of them,” Perez told me recently. “In 2008, my rookie year with St. Louis, we were in Florida at the old stadium, playing the Marlins. I came into the game in the eighth inning with one out, and got a double play with the bases loaded. When I went back to the dugout, Tony La Russa told me, ‘Hey, Chris, you’re still in there. Stay focused, because you’ve got the ninth.’”

The Cardinals were up by a run at the time, and Perez was due up sixth in the top half. Three hits and two outs later — an insurance run having crossed the plate — La Russa approached Perez again. This time the message was less welcome: “Go up to the plate and look dangerous, but don’t swing. I want you to take every pitch.”

La Russa was a veteran manager on his way to the Hall of Fame. Perez was a fresh-faced rookie. He took every pitch. Read the rest of this entry »


Effectively Wild Episode 1643: In Theo We Trust?

DJ LeMahieu Is Back in the Bronx

The staredown is over, and the first of this winter’s top-tier free agents has signed. Per ESPN’s Jeff Passan, the Yankees are finalizing a six-year, $90 million deal to bring back DJ LeMahieu, who over the past two seasons has been one of the game’s top hitters and most valuable players.

That outcome — a surprise given his latter-day performances with the Rockies — has a whole lot to do with the way the now-32-year-old infielder adapted to the Bronx, to such an extent that “The Machine” likely has more value to the Yankees than to any other team. Even so, this is a comparatively reasonable deal that fits the Yankees well, as its lower average annual value will aid the team when it comes to the Competitive Balance Tax. At the same time, from a dollars-and-wins standpoint, it may not bode tremendously well for this winter’s other top free agents.

When the Yankees signed LeMahieu to a two-year, $24 million deal, he was coming off a tepid 91 wRC+ over the final two seasons of his seven-year run in Colorado. Even so, his glovework had boosted his value to 4.1 WAR in that span, giving him a reasonable floor, and our own Jeff Sullivan saw his high contact rate, right-handedness, ability to hit to the opposite field, and modest pop as reminiscent of one Derek Jeter. Due to a slew of injuries, the Yankees leaned upon LeMahieu more than most observers expected, and between his defensive versatility and indeed, his ability to go oppo with his fly balls — thereby taking advantage of Yankee Stadium’s short right field porch — he emerged as one of the toughest outs in the league.

LeMahieu, who had reached double digits in home runs just twice with the Rockies and topped out at 15 in 2018, hit a major league-high 16 opposite field homers at home in 2019-20 (out of 36 total) while continuing to pull enough groundballs hard enough to put up eye-opening numbers. After batting .327/.375/.518 (136 wRC+) with 5.4 WAR in 2019, he hit a sizzling .364/.421/.590 in ’20. His batting average in the latter season made him the first modern player to win batting titles in both leagues; Ed Delahanty won the NL in 1899, and the AL in 1902, his last full season before going over Niagara Falls.

The Giants Have Quietly Rebuilt Their Rotation

The Giants continued to remake their starting rotation this week, signing former Dodgers swingman Alex Wood to a one-year, $3 million contract. Wood’s low salary reflects the fact that he’s struggled over the last two seasons, accumulating -0.2 WAR in 48 1/3 innings, courtesy of a bleak 6.02 FIP. The catch is that he was not truly healthy in either campaign, missing much of 2019 with back issues and a chunk of ’20 with shoulder inflammation. While he’s never been the picture of perfect health — he hasn’t qualified for an ERA title since 2015 — he was a key contributor to the Braves and the Dodgers, and before his disappointing 2019, his worst FIP over a season was 3.69 in ’15, a number many pitchers would be delighted to hit.

Similar to about 27 or 28 teams in baseball, San Francisco hasn’t made a splash this winter, but there’s been a real push to improve the starting pitching. Back when the Giants were winning a World Series every other season, a large part of the foundation was young, team-developed pitching. Few teams could match the accomplishment of producing Matt Cain, Tim Lincecum, and Madison Bumgarner over a rather short period of time. But since the team’s collapse in 2017, a year in which the Giants just barely avoided their second 100-loss year in franchise history, the rotation has been one of the worst in the league, ranking 25th in WAR. Any sort of magic at creating young aces seems to have dissipated, with a long list of names — Kyle Crick, Keury Mella, Tyler Beede, Ty BlachClayton Blackburn — failing to make an impact.

The Phillies Continue to Add Firepower to Their Bullpen

Last year, the Phillies’ disastrous bullpen was a major reason why they missed out on the playoffs for the ninth consecutive season. If you go back to 1969 — the year MLB lowered the mound — the 2020 Phillies bullpen posted the absolute worst league-adjusted ERA in a single season. By FIP, they were only a little better, landing 16th worst among 1,438 team seasons. Upgrading the bullpen had to be a significant focus of their new front office tandem, president of baseball operations Dave Dombrowski and general manager Sam Fuld.

Their problems were numerous, but the Phillies’ relief corps suffered from a significant lack of gas in 2020. Their relievers threw the second lowest rate of fastballs thrown over 95 miles per hour in 2020. Indeed, just 10.5% of them reached that threshold. To address this dearth of heat, the Phillies have added a bunch of relievers who throw extremely hard fastballs. Just before the calendar flipped to 2021, they added José Alvarado in a three-way trade with the Rays and Dodgers — Alvarado’s fastball averages 97.7 miles per hour. Then a week ago, they acquired Sam Coonrod from the Giants — his heater comes in even faster at 98.7 mph. And yesterday, they added a third hard-throwing reliever to their bullpen, signing Archie Bradley to a one-year, $6 million contract. Adding elite fastball velocity won’t be a panacea for all their woes, but it should help.

Bradley’s fastball is the slowest of the bunch, averaging 94.4 mph in 2020. That’s actually a point of concern. It was the lowest average velocity for his four-seamer since he transitioned to the bullpen full-time in 2017.

Despite the drop in velocity, Bradley posted the best FIP of his career last season. His strikeout rate dipped a bit, from 27.4% to 24.7%, but he also slashed his walk rate to just 4.1%. In 2019, he had survived as the Diamondbacks closer with a 11.4% walk rate. During that season, his rate of pitches thrown in the zone dipped below league average for the first time as a reliever. He reversed that trend in 2020, getting his zone rate just above league average.

That dip in strikeout rate is just as concerning as his lower velocity. His fastball’s whiff rate was right in line with where it had been in years past. The biggest change for him in 2020 was the number of swinging strikes he was getting on his curveball. The whiff rate on his bender dropped from 30.5% to just 16.7%. Like his fastball, his curveball lost velocity last year, dropping down to 80 mph on average. It’s possible that lost velocity affected the effectiveness of the pitch enough to cause batters to spit on it more often. Now, he did record the highest rate of called and swinging strikes of his career in 2020, so it’s also possible that his falling strikeout rate was simply poor sample size luck.

The only reason why his overall swinging strike rate didn’t budge all that much in 2020 was because of his changeup. That third pitch had been a part of his repertoire back when he was a starter but it was inconsistent and he often lost his feel for it. He brought it back in 2019 with some success and increased his usage of it to 11.6% last year. He threw just 32 changeups in 2020, but its 38.9% whiff rate would have ranked 18th among all changeups thrown at least 100 times during the season.

Beyond his downward sloped strikeout and walk rates, Bradley worked through some odd results when opposing batters put his pitches in play. He induced the lowest hard hit rate of his career while also allowing the highest barrel rate of his career. His expected wOBA on contact of .370 was just a hair below league average so those additional barreled balls didn’t do much damage — he allowed just a single home run in 2020. His groundball rate had consistently been above league average throughout his career but it dipped below average for the first time in 2020. He threaded a very narrow needle by allowing more contact in the air, even though it was a little weaker contact overall, all while pitching in the zone more often with a fastball that was thrown a little less hard.

It was a bit of a surprise that Bradley was available as a free agent at all. He was entering his final year of arbitration and had pitched decently enough for the Reds after they acquired him at the trade deadline. But with all these red flags and concerning trends, you can see why they decided to non-tender him. He ended up getting a contract around his estimated arbitration salary anyway. If he can find that lost velocity on his fastball and curveball and continue to refine his changeup, he should be a stabilizing presence for the Phillies bullpen.

Simply based on his track record, Bradley will likely enter the season with at least a job-share in the ninth inning with Héctor Neris. Like every other Phillies reliever last year, Neris had his own problems and lost his handle on the closing duties when Brandon Workman was brought in. Between Bradley, Neris, and Alvarado, they’ll have plenty of options should any of them falter during the season. But there are enough question marks between the three of them that the Phillies should probably be in the market for another reliever, just in case.


League Expansion, Interest Rates, and Other Fun Friday Topics

Earlier this week, Ken Rosenthal reported that owners are unlikely to pursue expansion plans in the near future. At first, that sounds strange. Why would owners who are experiencing a cash crunch turn down a quick cash infusion, reportedly nearly $70 million per team? As it turns out, the math is straightforward. Let’s talk about perpetual cash flows, debt equivalence, and other fun stuff like that.

Per Rosenthal’s reporting, owners would stand to make an aggregate $2 billion from expansion fees, or $1 billion per new team. Split 30 ways, that amounts to $66.7 million per team, which would go a long way for clubs who are acting phenomenally cash-light. In exchange, however, they’d give up a small share of a lucrative enterprise that makes owning a baseball team a cash cow.

Again per Rosenthal, the league projected to make $2.4 billion in central revenue in 2020 before the pandemic laughed in the face of advance planning. Central revenue is everything generated by MLB rather than by individual teams — national TV contracts, national sponsorships, streaming revenue, consumer product sales, and assorted other line items, with TV contracts comprising the lion’s share of the money.

That works out to $80 million per team, and adding two teams to the mix would dilute teams’ share of the pie. With 32 teams, each team would only get $75 million in central revenue per year. That might not sound like much — $5 million over time weighed against $67 million in cold hard cash right now — but big enterprises like baseball teams don’t need to act to maximize their liquidity. They instead seek to maximize net present value, which is a financially stylized way to consider the value today of money you might receive in the distant future.

This is going to get annoyingly math-y, but I’ll try to keep it in somewhat relatable terms, so bear with me. Say your friend offers you the choice of $100 today or $200 in a year. Presumably, you’d prefer the $200 — it’s twice as much money! Things get trickier, however, if it’s a choice between $100 today or $110 in a year, or between $100 today and $200 in 20 years.

Top 39 Prospects: Minnesota Twins

Below is an analysis of the prospects in the farm system of the Minnesota Twins. Scouting reports were compiled with information provided by industry sources as well as my own observations. As there was no minor league season in 2020, there are some instances where no new information was gleaned about a player. Players whose write-ups have not been altered begin by telling you so. For the others, the blurb ends with an indication of where the player played in 2020, which in turn likely informed the changes to their report. As always, I’ve leaned more heavily on sources from outside the org than within for reasons of objectivity. Because outside scouts were not allowed at the alternate sites, I’ve primarily focused on data from there. Lastly, in effort to more clearly indicate relievers’ anticipated roles, you’ll see two reliever designations, both in lists and on The Board: MIRP, or multi-inning relief pitcher, and SIRP, or single-inning relief pitcher.

For more information on the 20-80 scouting scale by which all of our prospect content is governed, you can click here. For further explanation of Future Value’s merits and drawbacks, read Future Value.

All of the numbered prospects here also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It can be found here.

Editor’s Note: Danny De Andrade was added to this list after he agreed to a deal with the Twins on January 15.
