The Athletics announced on Friday that they’ve designated outfielder Brett Eibner for assignment in order to clear a spot on the 40-man roster for right-hander Santiago Casilla, whose two-year deal with the club is now official.

The 28-year-old Eibner’s stay with Oakland proved to be short-lived, as he was acquired from the Royals this past July in a straight-up swap for fellow outfielder Billy Burns. Eibner made his Major League debut with the Royals this season and also logged 123 plate appearances with Oakland, though he didn’t produce at the plate with either club. In a total of 208 trips to the plate, Eibner batted just .193/.266/.353.

Eibner, though, can play all three outfield positions and has a quite productive track record in Triple-A, where he’s spent parts of three seasons. At the top minor league level, Eibner’s a .280/.356/.474 hitter with 38 homers and 20 steals in 979 plate appearances. While he’s never rated as an elite prospect, he was a mainstay on Baseball America’s top 30 Royals prospect lists from 2010-15, ranking 17th as recently as two winters ago. BA noted that Eibner is a plus defender in center and an above-average runner with 15-homer pop. However, he’s also extremely streaky and prone to prolonged slumps, per their most recent report.

Eibner does have minor league options remaining, so any team that picks him up could send him to the minors without exposing him to waivers and utilize him as a depth piece even if there’s no immediately available place on the 25-man roster.
