Rivero spent the past two seasons at Double-A Akron, where he hit .237 during those two seasons. In his career, he's hit a combined .255 over five minor league seasons in the Indians organization.
Defensively, Rivero has spent the vast majority of his time at shortstop, but played nine games at third base back in the 2006 season. There has also been talk that he could potentially be moved to second. It's most likely that Rivero will be assigned to either Double-A Reading or Triple-A Lehigh Valley to start the 2011 season.
The Phillies have Freddy Galvis and Brian Bocock to play shortstop at the upper levels of the minors. Rivero could also possibly be moved to find a position for him at either Lehigh Valley or Reading.
Besides Galvis and Bocock, the Phillies have Harold Garcia, who can play at either second or third and Cody Overbeck, to play at third. Both Garcia and Overbeck spent part of the season at Double-A Reading and either one or both of them could be in line for a promotion to Lehigh Valley. If only one of them makes the jump, it would likely be Garcia, who had good numbers at both Clearwater and Reading last season.
