Cardinals GM John Mozeliak said Wednesday that Oscar Taveras could "possibly" be called up when the club begins a stretch in American League parks on June 4. St. Louis will visit the Royals, Blue Jays, then Rays in a seven-game road trip from June 4-11. That means that the DH spot will be available, and the Cardinals could cycle Allen Craig and Matt Adams through that role while offering Taveras starts in right field. The 21-year-old top prospect is batting .390/.422/.585 over his last 10 games at Triple-A Memphis and has 85 total bases in 42 total games this season in the Pacific Coast League. He's worth stashing right now in standard fantasy formats.
