Mariners righty Hisashi Iwakuma has been shut down for ten days to two weeks after experiencing continued upper back tightness, Ryan Divish of the Seattle Times reports. “He’s going to be pushed back, so to speak,” said manager Lloyd McClendon. “His rehab has not gone as well as we thought it would have gone. He’s still experiencing some stiffness.” The longer Iwakuma is delayed, the more it begins to look like another arm might be a trade deadline consideration for Seattle.
- Meanwhile, the Red Sox rotation woes worsened last night with a rough outing for Justin Masterson. As Gordon Edes of ESPNBoston.com reports, manager John Farrell indicated that there is cause to believe there is more to be concerned with than the poor results. “The last two times out for Justin have not been anywhere close to what he’s shown this year — set aside prior to the start of 2015,” said Farrell. “Clearly, he’s not right. Whether that’s physical, whether that’s delivery-wise, the ball is not coming out of his hand as he’s shown the better part of the year. We’ve got to gather information, we’ve got to check on him in the morning, get a full workup, get a better assessment of where things are.”
- Of course, it’s far from clear that there is any realistic possibility of an outside addition to the Red Sox staff in the immediate future. As Alex Speier of the Boston Globe explains, utilizing the MLBTR Transaction Tracker, history teaches that starters (at least, impactful ones) are rarely dealt in the season’s first two months. Regardless, the club figures to be at or near a breaking point with its current starting five, and it would be surprising if internal replacements — Eduardo Rodriguez, most interesting among them — are not at least given a chance as the summer draws near.
- The Orioles are holding their breath after 20-year-old prospect Hunter Harvey left an outing with elbow tightness, as Eduardo Encina of the Baltimore Sun reports. The rising Harvey, who is coming back from a shin fracture suffered this spring, already was shut down late last year with some elbow concerns and now is set for an MRI. His health and progress is critical to the organization, particularly with Dylan Bundy dealing with his own elbow problems and with the aforementioned Rodriguez shipped out at last year’s trade deadline.
