Orioles' LHP John Means to undergo an MRI on his shoulder on Sunday?

John Means left his start today in the first inning with what’s currently being identified as “left shoulder fatigue,” per Rich Dubroff of Baltimorebaseball.com. Said Means after the game, “This is something I’ve been battling the last few weeks. Not really during the games, but after games. I felt it more so in warmups when I was out there, the last couple of pitches when I really started to let it eat. I felt it kind of yank and then every pitch after that, I felt it on the end of extension.” The O’s lefty will undergo an MRI on Sunday morning. Elsewhere in the American League…

• The Twins have not gotten the kind of production they need from Matt Shoemaker this season. The 34-year-old veteran gave up eight earned runs while recording just one out against the Royals on Friday. For the season, Shoemaker’s 7.28 ERA/5.98 FIP rank last by a fair margin among starters with at least 50 innings this season. He will continue to make his turns in the Twins’ rotation for now, per the Athletic’s Dan Hayes.
• Even if the Twins wanted to make a move, they’re somewhat hampered by recent injuries to their Triple-A pitching staff. Both Lewis Thorpe and Matt Canterino were placed on the Triple-A injured list on Saturday, per Do-Hyoung Park of MLB.com (via Twitter). They are dealing with a left shoulder strain and right elbow strain, respectively. Canterino, pitching in High-A, was not likely to help out at the big league level this season, but Thorpe already has 14 innings in four appearances (three starts) with the Twins this season. He has pitched exclusively out of the pen at Triple-A.
• J.D. Martinez was a late scratch from Boston's lineup with a sore wrist, per Pete Abraham of the Boston Globe (via Twitter). He appeared to jam his wrist sliding into second base during a play on Friday. The injury does not appear to be serious. Per Christopher Smith of Masslive.com, manager Alex Cora commented on the situation, saying, “…we’ll take care of him today, get treatment. If he feels good and we need him late in game, then probably we’ll use him.”
• Aledmys Diaz will undergo x-rays after being hit by a pitch and suffering a left hand contusion, per Mark Berman of Fox 26 (via Twitter). Diaz would be missed. He’s posted a solid .281/.339/.439 line in 124 plate appearances this season.
