Mariners' Justus Sheffield: Fans eight in rough start
by RotoWire Staff | RotoWire

Sheffield allowed six runs (five earned) on six hits and a walk over 4.1 innings Sunday, striking out eight in the win over the White Sox.

Sheffield had allowed just one run in 11 innings this month but couldn't find similar results Sunday. He cruised through four scoreless frames before getting hammered in the fifth for all six runs he allowed. On the bright side, the eight-strikeout performance sets a new career-best for the rookie southpaw. He'll carry a 5.40 ERA into Saturday's matchup in Baltimore.

Mariners' Justus Sheffield: Allows one run in no-decision
by RotoWire Staff | RotoWire

Sheffield did not factor into the decision against Cincinnati on Tuesday, pitching six innings and giving up one run on seven hits and three walks while striking out four.

Sheffield hurled his second straight impressive outing, allowing only a second-inning run in six innings of work to notch the first quality start of his major-league career. He allowed 10 baserunners but skillfully worked his way out of trouble by inducing four double plays. The rookie has allowed only one run in last 11 innings to lower his season ERA to 4.43. He'll look for his first career victory when he takes on the White Sox on Sunday.

Mariners' Justus Sheffield: New start date cemented
by RotoWire Staff | RotoWire

Sheffield will make his next start Tuesday against the Reds, Greg Johns of MLB.com reports.

The rookie was originally slated to go Sunday against the Astros on five days rest, but he'll be even more refreshed now that Felix Hernandez will take the ball against Houston instead. Sheffield's workload will continue to be closely monitored after he logged a total of 133 minor-league innings this season between Double-A Arkansas and Triple-A Tacoma.

Mariners' Justus Sheffield: Likely to have start pushed back
by RotoWire Staff | RotoWire

Sheffield will likely have his next start pushed back, Shannon Drayer of 710 ESPN Seattle reports.

Sheffield was originally expected to get the ball Sunday against the Astros, but with the Mariners monitoring his workload down the stretch, it sounds like the team is leaning toward giving the southpaw some extra rest before his next start while going with a bullpen game Sunday. Through four appearances with the Mariners this season, Sheffield has a 5.51 ERA and 18:9 K:BB across 16.1 innings.

Mariners' Justus Sheffield: Strikes out seven in no-decision
by RotoWire Staff | RotoWire

Sheffield gave up no runs on five hits and two walks while striking out seven through five innings in a no-decision against the Cubs on Monday.

Sheffield delivered a nice outing, but he labored a little, throwing 91 pitches in his five innings of work. The 23-year-old generated 21 swinging strikes, 14 on his slider alone. Sheffield has a 5.51 ERA with an 18:9 K:BB through three starts this season. Sheffield is scheduled to make his next start Sunday at Minute Maid Park.

Mariners' Justus Sheffield: Loses first start
by RotoWire Staff | RotoWire

Sheffield (0-1) allowed five runs on six hits with no walks and five strikeouts across 4.1 innings while taking a loss against the Yankees on Wednesday.

Through three outings, Sheffield has yet to generate a decent performance. While he didn't walk anyone Wednesday and pitched deeper into this contest than either of his previous two starts this year, Sheffield yielded two homers. He owns a 7.94 ERA, 1.94 WHIP and 11 strikeouts versus seven walks in 11.1 innings this season. Sheffield will start at the Cubs in his next outing Monday.

Mariners' Justus Sheffield: Facing former team for next start
by RotoWire Staff | RotoWire

Sheffield will stick in Seattle's rotation and make his next start Wednesday versus the Yankees, Greg Johns of MLB.com reports.

He'll be squaring off against Yankees southpaw James Paxton, the headliner in the offseason deal that sent Sheffield, pitcher Erik Swanson and outfielder Dom Thompson-Williams to Seattle. The matchup with one of his former organizations should provide some extra motivation for the 23-year-old, but he'll likely be prone to volatile outings while he continues to get his feet wet at the big-league level. Sheffield wasn't especially effective in his first MLB start against a middling Blue Jays squad over the weekend, lasting only four innings while giving up three runs on seven hits and three wakls.

Mariners' Justus Sheffield: No-decision versus Jays
by RotoWire Staff | RotoWire

Sheffield allowed three runs on seven hits and three walks Friday, striking out three over four innings. He did not factor in the decision as the Mariners won 7-4 over the Blue Jays.

Sheffield was making his first major-league appearance in four months, but he didn't pitch long enough to be eligible for the win in a back-and-forth contest. Through seven innings this year, Sheffield has allowed five runs on a combined nine hits and seven walks while striking out six. With Wade LeBlanc getting booted from the Seattle rotation, the rookie is expected to remain in a starting role down the stretch, with his next start coming at home versus the Yankees on Wednesday.

Mariners' Justus Sheffield: Recalled ahead of Friday's start
by RotoWire Staff | RotoWire

Sheffield was recalled from Double-A Arkansas to start Friday against the Blue Jays.

Sheffield was named Friday's starter earlier this week, so his promotion was to be expected. The 23-year-old made his debut with the Mariners in April and allowed two runs over three innings. Sheffield was demoted to Double-A after scuffling at Triple-A Tacoma earlier this season, and he responded with a 2.19 ERA, 1.03 WHIP and 85:18 K:BB through 78 innings with Arkansas.

August 20, 2019 06:04 PM
Mariners' Justus Sheffield: Slated to start Friday
by RotoWire Staff | RotoWire

Sheffield is expected to be recalled from Double-A Arkansas to start Friday's game against the Blue Jays, Shannon Drayer of 710 ESPN Seattle reports.

Sheffield will enter Seattle's starting rotation for at least one outing while Yusei Kikuchi catches a breather. With Felix Hernandez (lat) expected to return from the injured list Saturday, Sheffield could be in line for a bullpen role with the big-league club following Friday's spot start.

August 16, 2019 11:16 PM
Mariners' Justus Sheffield: Late-August callup likely
by RotoWire Staff | RotoWire

Sheffield, who's been considered a candidate for a promotion from Double-A Arkansas to start this Saturday against the Blue Jays, is more likely to be called up toward the end of August, Ryan Divish of The Seattle Times reports.

Sheffield last took the mound for the Travelers on Sunday, so the timing of a potential spot start Saturday wouldn't be an issue. Neither are Sheffield's credentials, considering he's gone 5-2 with a 1.75 ERA and 79:16 K:BB over 72 innings at the Double-A level since being demoted from Triple-A Tacoma. However, general manager Jerry Dipoto emphasized Wednesday that a promotion toward the end of August would be the ideal scenario, with the Mariners more likely to go with a bullpen-day strategy in the middle game of the series against Toronto this coming weekend.

Mariners' Justus Sheffield: Candidate to join rotation
by RotoWire Staff | RotoWire

Sheffield is a candidate to be called up from Double-A Arkansas to start Saturday against the Blue Jays, Greg Johns of MLB.com reports.

Sheffield last started for Arkansas on Sunday, so he would be pitching on an extra day of rest should he be tabbed to join the big-league rotation when Seattle needs a fifth starter Saturday. The 23-year-old lefty struggled with Triple-A Tacoma to open the season, but he's been sharp since being demoted to Double-A in mid-June, compiling a 1.75 ERA, 1.00 WHIP and 79:16 K:BB across 11 starts (72 innings) with Arkansas.

Mariners' Justus Sheffield: Candidate to fill rotation spot
by RotoWire Staff | RotoWire

Sheffield is a candidate to be called up and fill in the rotation spot left open by the trade of Mike Leake on Wednesday, Ryan Divish of The Seattle Times reports.

Leake made his last start for the Mariners on Tuesday, so his next turn would have normally come up next Monday. However, with Seattle off Thursday, next Monday and next Thursday, they will have plenty of time to make a decision on who'll slot into the vacancy. Sheffield had a rough start to the season at Triple-A Tacoma, but he's generated a 4-2 record, 1.69 ERA, .221 BAA, 1.05 WHIP and 56:13 K:BB across eight starts since being demoted to Double-A Arkansas in mid-June.

Mariners' Justus Sheffield: Sharp since demotion
by RotoWire Staff | RotoWire

Sheffield, who took a no-hitter into the eighth inning for Double-A Arkansas against Tulsa on Saturday, has allowed just three earned runs and recorded 24 strikeouts over his first three starts since being demoted to the Travelers.

Sheffield was sent down from Triple-A Tacoma on June 14 after a disastrous three-start stretch with the Rainiers where he gave up 20 earned runs across seven innings. The downgrade in competition has done wonders for the left-hander, who worked a season-high eight innings Saturday and has exhibited much better control since the demotion as well. Sheffield's 2019 ERA remains an unsightly 5.40 primarily due to his aforementioned multi-appearance skid, but his 1.35 ERA and 0.90 WHIP thus far in Arkansas offers reason for optimism.

Mariners' Justus Sheffield: Demoted to Double-A
by RotoWire Staff | RotoWire

Sheffield was sent to Double-A Arkansas on Friday, Shannon Drayer of 710 ESPN Seattle reports.

Sheffield has struggled at Triple-A so far this season, so the Mariners have elected to give him some time at a lower level to regain his confidence. He's posted a 6.87 ERA with a 48:41 K:BB over 55 innings this season for the Rainiers.

June 2, 2019 02:40 AM
Mariners' Justus Sheffield: Not a candidate for spot start
by RotoWire Staff | RotoWire

Sheffield is not a candidate to start Tuesday's game against the Astros in place of Yusei Kikuchi, Greg Johns of MLB.com reports.

The fact the left-hander started Saturday's game for Triple-A Tacoma removes him from consideration to return to the majors for the second time this season. Sheffield appears to still be in need of plenty of seasoning anyhow, considering he allowed seven earned runs on six hits and five walks over 2.2 innings against El Paso on Saturday.

Mariners' Justus Sheffield: Best outing of season
by RotoWire Staff | RotoWire

Sheffield earned his second victory of the season in Triple-A Tacoma's win over Fresno on Wednesday, allowing an earned run on seven hits and a walk over seven innings. He struck out two.

The most encouraging aspect of Sheffield's strong effort may have been his control, as the one free pass he issued was a season-low figure. The southpaw now has his two longest outings of the season over his last two trips to the mound, and he'll look to continue improving his control down on the farm in anticipation of a likely promotion at some point this season.

Mariners' Justus Sheffield: Not getting promoted yet
by RotoWire Staff | RotoWire

Sheffield, who is 1-2 with a 4.38 ERA across seven starts for Triple-A Tacoma, is not expected to be promoted to fill the rotation spot that opened up when Erik Swanson was optioned to the Rainiers, Greg Johns of MLB.com reports. "I think when we get to the point where we call Justus up, we'd like to call him up and leave him here and let him go," manager Scott Servais said. "I don't want to call him up and give him one or two outings and then go back and forth. He's working on things right now."

Sheffield already had his first major-league cameo earlier this season, filling in as the bulk reliever for Yusei Kikuchi's first abbreviated start April 26. However, a second major-league go-around apparently isn't in the works for now, even with the Mariners needing to fill the new vacancy in their rotation as soon as Tuesday against the Rangers. Sheffield will instead continue to concentrate on his development with the Rainiers, where he's been focusing on developing his changeup and attempting to refine his control.

Mariners' Justus Sheffield: Bounces back after rough outing
by RotoWire Staff | RotoWire

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.

April 27, 2019 07:00 PM
Mariners' Justus Sheffield: Returns to Triple-A
by RotoWire Staff | RotoWire

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.
