Dodgers Grab Zach Britton Lite in Three-Team Deal by Travis Sawchik January 4, 2018 While everyone waits for the thaw of the free-agent market, the Dodgers, Royals, and White Sox got together on a three-team trade Thursday evening. The L.A. Times‘ Andy McCullough broke the news on the deal, as part of which the Royals send lefty reliever Scott Alexander to the Dodgers for prospects Erick Mejia and Trevor Oaks. The Dodgers ship lefty reliever Luis Avilan and $3 million to the White Sox. The Royals are also reportedly moving Joakim Soria and $1 million to the White Sox in something of a salary dump. Sources: The Dodgers are close to finalizing a three-team trade that would bring LHP Scott Alexander to LA, send RHP Trevor Oaks to KC and send LHP Luis Avilan to White Sox. — Andy McCullough (@McCulloughTimes) January 4, 2018 The final accounting of this three-team trade: Royals sending Scott Alexander to the Dodgers and Joakim Soria to the White Sox; they're receiving right-hander Trevor Oaks and infielder Erick Mejia from Dodgers. — Rustin Dodd (@rustindodd) January 5, 2018 While there are quite a few moving parts, the focus within this post will be on Alexander, an interesting arm who could fill a need — and fill it cheaply — for one of the top clubs in baseball. Lefty reliever Tony Watson is a free agent, and the Dodgers are attempting to stay under the luxury tax. In giving up prospects and cash, the Dodgers must also feel Alexander is an upgrade over Avilan, who is projected to make $2.3 million in arbitration according to MLB Trade Rumors. Alexander, a pre-arbitration arm with five years of control remaining, might not only fill a need cheaply for the next couple of seasons but also exceptionally well. While, on the one hand, the Dodgers are trading a lefty who misses bats, they’re also adding a lefty who might have more upside in today’s offensive environment. In a year marked by fly balls, home runs, launch angles, and juiced balls, Alexander was, by some measures, the top ground-ball arm in the game in 2017. The approach led him to a 2.48 ERA, 3.23 FIP, and 56 ERA- last season over 69 innings. He emerged, quietly, as one of the better relievers in the game. Among pitchers who threw at last 20 innings last year, Alexander led baseball in ground-ball rate (73.6%). He was one of only three pitchers to post a mark of 70% or greater, joining Marc Rzepczynski (70.0%) and Zach Britton (72.8%) in that small club. And it is Britton who could become a frequent comp for Alexander, thanks to latter’s darting sinker and handedness. Not only are Britton and Alexander left-handed arms who finished Nos. 1 and 2 in ground-ball rate last season among all pitchers, they also placed first and second in reliance upon sinkers. Britton threw the pitch 95.1% of the time; Alexander, 91.9%. The next most frequent usage was recorded by Brandon Kintzler (74.4%). The 28-year-old Alexander has been a ground-ball pitcher since he reached High-A in 2013. And by last season, his two-seamer had developed into one of the best pitches in baseball. His emergence is due, in no small part, to added velocity: Alexander’s sinker jumped 3 mph between 2016 and -17, from 90.7 to 93.2 mph. According to Baseball Prospectus’s PITCHf/x leaderboards, the pitch ranked fifth in baseball among all sinkers (minimum 200 thrown) in swing-and-miss rate (28.1%) and 21st in GB/FB ratio (8.1). He leaned on the pitch — and kept leaning on it — because it worked. Batters vs Scott Alexander had an average launch angle of -4.6 degrees in 2017. 2nd lowest of any pitchers with 150 BIP. #GroundballMachine pic.twitter.com/AsLauke34q — Daren Willman (@darenw) January 5, 2018 Perhaps one criteria for the excellence of a pitch is if the opposition expects it and yet fails to hit it anyway. Scott Alexander's pitch chart from last year is pretty monochromatic. Not exactly a man of mystery … but it worked. pic.twitter.com/O3Xy8ywjnE — Andrew Simon (@AndrewSimonMLB) January 5, 2018 The following represents video evidence of the sinker’s darting effectiveness, a sequence from last season against Corey Seager: And against Mikie Mahtook: Both last season and also over the course of his brief career, Alexander has been more effective against righties, allowing wOBAs of .292 and .314, respectively, versus right- and left-handed batters. He is not doomed to situational status. The deal makes sense for the Dodgers: they add to their bullpen but do so without endangering their luxury-tax status. At the moment, the Dodgers have a projected $184 million payroll in 2018. The tax threshold, meanwhile, stands at $197 million. The Royals are headed for a rebuild, and it makes sense to trade off relievers even if for marginal prospects while shedding payroll. The White Sox picked up cash and two quality veteran relievers — relievers they can perhaps flip this summer. It’s not a trade that is going to make major headlines, but it’s something that involves a top contender and an interesting arm. And to give up money and prospects in addition to Avilan, maybe the Dodgers believe they’ve found something.
