The Cardinals have announced that they’ve placed outfielder Stephen Piscotty on the 10-day DL with a right groin strain. To take his place on the active roster, they’ve recalled outfielder Magneuris Sierra from Double-A Springfield.
The move leaves the Cardinals conspicuously short in the outfield, having placed Randal Grichuk on the 10-day DL yesterday with a lower back strain. In place of those players, the Cardinals will lean on Jose Martinez and Sierra to flank Dexter Fowler and Tommy Pham in the Cards’ outfield.
Grichuk has struggled this season and Piscotty hasn’t been outstanding (.236/.348/.371), so the 28-year-old Martinez has out-hit both players in his first sustained bit of big-league action, with a .280/.321/.464 line over 135 plate appearances. The 21-year-old Sierra, though, might be over his head if given much playing time — he’s batted a good, but not excellent, .293/.326/.403 for Springfield and has limited experience above the Class A level. He did fare well in two brief big-league stints earlier this year. MLB.com rates him the Cardinals’ eighth-best prospect.
The Cardinals also have another strong outfield prospect in Harrison Bader who’s hit very well for Triple-A Memphis. Unlike Sierra, though, Bader isn’t currently on the club’s 40-man roster, which might be why the Cardinals promoted Sierra instead for a stint in the big leagues that might again be short.
