Roster juggling redux
May 17, 2019
The Mariners made yet more roster moves today, recalling pitchers Matt Festa and Ryan Garton from Triple-A Tacoma. Both will be available in the bullpen immediately. To clear space for them, southpaw reliever Zac Rosscup has been designated for assignment and alleged starting pitcher Erik Swanson was optioned to Tacoma.
Festa has already been with the Mariners once this season, appearing in six games from Opening Day through April 10th. In seven innings of work, he allowed five earned runs, all in the last two of his appearances totaling 12⁄3 innings. Garton made 13 appearances with the M's in 2017 after arriving in a late-season trade with Tampa Bay, allowing just two runs in 112⁄3 innings; since then he's toiled in Tacoma, doing a respectable if not particularly notable job (4-0, 3.28 ERA in 582⁄3 innings).
Both Festa and Garton are right-handers, so with the loss of Rosscup, the M's have just one left-hander in their bullpen, Roenis Elías, for the time being.
Rosscup did a reasonable job with the M's when facing lefties, whom he held to a .087 average, but got lit up by right-handers to the tune of .344. He also had an issue with walks, issuing and average of one base on balls per inning. If the Mariners are to retain Rosscup in their system, he will have to clear waivers, which is unlikely, and accept a minor-league assignment.
Swanson, acquired from the Yankees in the James Paxton trade, will return to Tacoma to work on his repertoire (hopefully).
The Mariners also made a waiver claim today, re-acquiring pitcher Andrew Moore, whom Seattle had earlier traded to the Rays in the deal for Denard Span and Alex Colomé early last season. Moore had been designated for assignment by the Rays and claimed by the Giants earlier this month, and today was DFA'd by the Giants, allowing the Mariners to re-claim him. He returns to the Mariners' 40-man roster, and to make room for him the M's have DFA'd not-ready-for-prime-time pitcher Nick Rumbelow.
