Sheffield gave up one run on five hits and four walks while striking out two over five innings in a no-decision against the A's on Friday night.
One run over five looks good at a glance, but he was walking a fine line with the four free passes and a homer allowed. Sheffield was probably due for a run of better luck after he had some unfortunate breaks against him in his prior two starts (9.35 ERA, 2.76 FIP in those two outings). The lefty ends the 2019 season with a 5.50 ERA and 1.72 WHIP in 36 innings with the big club, and should get a chance to compete for a rotation spot in spring training.
Sheffield allowed four earned runs on five hits and one walk while striking out five across 4.1 innings Saturday against the Orioles. He did not factor into the decision.
Sheffield gave up three runs in the second inning when he surrendered consecutive doubles that led to the majority of he damage. However, he was ultimately chased in the fifth inning when he gave up two hits and hit a batter to load the bases. It was a disappointing effort for Sheffield, and he's now allowed four or more earned runs in three of his last five starts, inflating his ERA to 5.81 and WHIP to 1.68 in 31 innings this season. His next and final outing of the campaign is currently projected to come Friday against Oakland.
Sheffield is slated to get two more starts before the conclusion of the regular season, Greg Johns of MLB.com reports.
Sheffield next lines up to face the Orioles on Saturday night before wrapping up his season against the postseason-contending Athletics on Friday, Sept. 27. The 23-year-old southpaw, who thrived with Double-A Arkansas this season after finding life in the hitter-friendly Pacific Coast League with Triple-A Tacoma a bit daunting, has acquitted himself reasonably well at the big-league level. Sheffield has experienced a couple of hiccups in the form of a pair of five earned-run outings, but he encouragingly put together a stellar two-start stretch versus the Cubs and Reds (one earned run allowed over 11 combined innings) and has demonstrated some of the same swing-and-miss upside (10.1 K/9 through 26.2 innings) he's flashed at times in his minor-league career.
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. He didn't factor into the decision.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
