The Dodgers announced a set of roster moves today, including the selection of left-hander Zac Rosscup’s contract from Triple-A. Infielder Edwin Rios was also called up to the majors, while Caleb Ferguson and Tony Gonsolin were optioned to Triple-A. To create a 40-man roster spot for Rosscup, A.J. Pollock was shifted to the 60-day injured list.
This will be the 25-year-old Rios’ first taste of Major League action, following five seasons in the Dodgers’ farm system after being a sixth-round draft pick in 2015. Rios is ranked as the 12th-best Dodgers prospect by MLB.com, whose scouting report touts Rios’ power, bat speed, and hard-contact ability. As you’d expect from a Dodgers player, Rios can play multiple positions; he has primarily been a corner infielder in his young career, though he has experience in left field over the last two seasons and a handful of appearances in right field.
Rios will add another left-handed bat to the L.A. roster, and functionally seems to fill more or less the same role as the hot-hitting Matt Beaty, another lefty-swinger. The Dodgers are no strangers to roster churn, of course, and have the comfort of a big lead in the NL West to mix and match their lineup while waiting for Pollock and Corey Seager to return from the IL.
This will be Rosscup’s second stint with the Dodgers, as he first joined the organization on a waiver claim in July 2018 before being let go after the season. Rosscup has already changed uniforms twice this season, and has a 4.80 ERA over 15 total innings for the Mariners and Blue Jays. Rosscup’s career has been defined by both a lot of strikeouts and a lack of control, and those two trends have continued this season to the tune of 22 strikeouts and 16 walks over his 15 frames of work.
Still, his lopsided career splits (left-handed hitters have a .536 OPS against Rosscup, compared to a 1.016 OPS from righty batters) make Rosscup a good LOOGY-type pitcher for a Los Angeles bullpen that is short on southpaw depth, as Julio Urias is the only other left-hander in the relief corps. Ferguson was posting solid numbers earlier in the season but has struggled badly as of late, allowing runs in five of his last seven outings while posting a 9.72 ERA over his last 8 1/3 innings pitched.
