Now playing first base for the Angels: Juan Rivera

Juan Rivera will become the ninth Angels player to start at first base this season after Manager Mike Scioscia made the outfielder part of his infield for Monday's game against Tampa Bay at Angel Stadium.

Rivera started taking ground balls at the position Sunday in advance of the move, though he had played there extensively in spring training a few years ago and filled in on an emergency basis for an inning during a game in 2008.

Rivera said through an interpreter that he liked the move, which will allow him to get more playing time after mostly being stuck on the bench since the Angels promoted outfielder Peter Bourjos from the minor leagues earlier this month.

Rivera said he would use Howie Kendrick's first baseman's glove. Rivera joins Kendrick, Kendry Morales, Mike Napoli, Robb Quinlan, Paul McAnulty, Michael Ryan, Kevin Frandsen and Brandon Wood as the Angels to start at first base this season. The most players they have used as a starter at any other position besides designated hitter this season is six in left field.
