The A’s announced a broad slate of roster moves Tuesday. In addition to their previously reported selection of Henry Bolte‘s contract from Triple-A, they’ve also selected Michael Stefanic‘s contract and placed shortstop Jacob Wilson on the 10-day injured list due to a left shoulder subluxation. Infielder Brett Harris was optioned to Triple-A as well, while minor league righty Eduarniel Núñez was designated for assignment. Additionally, the A’s noted that catcher Austin Wynns, whom they’d previously designated for assignment, cleared waivers and was released.

As covered this week, Bolte has been the hottest-hitting prospect in the minors. He’s a plus runner with developing pop who recently rattled off hits in an astonishing 12 consecutive plate appearances to boost his batting line to a mammoth .348/.418/.658. He’s popped a dozen homers, swiped 17 bags and should get plenty of run in center field with Denzel Clarke still on the shelf. Zack Gelof has been seeing a good bit of action in center, but the former second baseman will probably head back to the infield with both Wilson — whose known shoulder injury now has a formal designation — and Max Muncy on the injured list.

With two infielders shelved, the A’s will turn to Stefanic, who’ll be making his team debut. The longtime Angels farmhand has seen prior action in parts of four major league seasons. He’s mustered only a .227/.314/.267 slash in 289 big league plate appearances, but the 30-year-old Stefanic is a prolific Triple-A hitter. He’s played parts of six seasons at the top minor league level and touts a .326/.422/.447 batting line with a tiny 9.5% strikeout rate. Stefanic has marginal power, bottom-of-the-scale sprint speed and below-average defensive skills, but scouting reports from Baseball America, FanGraphs and MLB.com have placed 70 and 80 grades (on the 20-80 scale) on his pure hit tool over the years.

More to come.
