Athletics' Jhonny Pereda: Booted off 40-man roster

The Athletics designated Pereda for assignment Saturday, Jason Burke of SI.com reports.

Pereda has appeared in 19 games for the Athletics this season, slashing .175/.283/.225 with no homers and three RBI over 46 plate appearances. He's fared better in the minors with an .840 OPS for Triple-A Las Vegas, but the A's needed to clear a 40-man roster spot for pitcher Ken Waldichuk (elbow), who was activated off the 60-day IL and optioned to Las Vegas in a corresponding move.
