The A’s made a number of transactions before tonight’s series opener with the White Sox. Oakland activated reliever Kirby Snead from the 60-day injured list while recalling Rico Garcia and Jordan Diaz from Triple-A Las Vegas.
Right-handers James Kaprielian and Yacksel Ríos are headed to the 15-day IL, while infielder Jonah Bride was optioned to Vegas. To clear space on the 40-man roster for Snead’s return, the A’s transferred Mason Miller from the 15-day to the 60-day IL.
Snead is back in Mark Kotsay’s bullpen for the first time this year. He strained his throwing shoulder in Spring Training. One of four players acquired from the Blue Jays in the Matt Chapman deal, Snead tossed 44 2/3 innings of 5.84 ERA ball during his first season in Oakland. He has allowed four runs in five innings in Triple-A on a rehab stint.
Kaprielian has a shoulder strain of his own, Kotsay told reporters (including Martín Gallegos of MLB.com). Ríos is battling Raynaud’s syndrome, a condition in which blood flow to a person’s hand can be diminished, thereby leading to numbness. The return timetable on both pitchers is unclear.
Miller has already missed just under two months with a sprain of the UCL in his throwing elbow. That makes his transfer a formality, though his long-term prognosis is still up in the air. Kotsay said Miller will soon go for follow-up examination (via Gallegos). The hard-throwing rookie has been throwing off flat ground for a few weeks and will continue his throwing program pending that evaluation.
In other injury news, catcher Manny Piña has reported to Low-A Stockton for a rehab stint, according to his transaction log at MLB.com. Acquired from the Braves to offset salary in the Sean Murphy deal, Piña has missed the entire season with a left wrist issue. He underwent surgery on the same wrist last May and hasn’t played an MLB game in 14 months.
