Sheffield picked up his first victory of the season in Triple-A Tacoma's win over Albuquerque on Monday, allowing an earned run on four hits and three walks across 5.1 innings while recording five strikeouts.
It was a strong rebound for the promising southpaw, who'd handed out six free passes over just 2.2 frames against Salt Lake last Wednesday, his first start since a brief trip up to the majors. Sheffield's control remains his Achilles heel, but he was able to locate enough Monday to turn in his longest outing of the season. The fact he needed 94 pitches to record 16 outs still speaks to how much room for improvement there is in that category, but perhaps the solid outing will serve as a launchpad to a string of improved performances.
Sheffield was optioned to Triple-A Tacoma on Saturday.
Sheffield will return to the Rainiers as expected after allowing two runs over three innings during his Mariners debut Friday. The 22-year-old was called up to cover some innings with Yusei Kikuchi limited to only one inning due to his maintenance plan. Sheffield figures to see the majors again at some point this season, perhaps in a similar role.
Sheffield served as the long reliever behind Yusei Kikuchi in an extra-innings win over the Rangers on Friday, allowing two earned runs on two hits and four walks over three innings. He struck out three.
The control problems the rookie has been experiencing at Triple-A Tacoma made the short trip with him to Seattle, as Sheffield needed 75 pitches to get through just a trio of frames. Only 39 of his offerings found the strike zone, but his ability to miss bats was evident in the eight swinging strikes he recorded overall. Sheffield is expected to return to the Rainiers to continue his development, with a possible callup later in the season certainly within the realm of possibility.
Sheffield won't start Friday against the Rangers, but he'll be the primary pitcher after Yusei Kikuchi throws as an opening. According to Ryan Divish of The Seattle Times, the 22-year-old is expected to return to Triple-A Tacoma following Friday's game.
Sheffield will be called up from Triple-A Tacoma to serve as the primary pitcher behind Yusei Kikuchi in Friday's game against the Rangers, Ryan Divish of The Seattle Times reports.
Kikuchi will be limited to one or two innings Friday as part of his maintenance program and Sheffield will be recalled to pitch after him. The 22-year-old began the season working as a starter at Tacoma, but covered three innings as a reliever Monday in preparation for his callup. Sheffield has a 3.93 ERA, 1.49 WHIP and 11:14 K:BB across 18.1 innings this season
