Key

Catchers

Lou Marson, C, Cleveland Indians

Messiah Carlos Santana displaced Marson earlier this year, but Santana sustained a left knee sprain this past weekend and is on the 15-day DL. The Tribe called up Marson, who'll presumably take over starting duties for the foreseeable future.

Bonjour, Bourjos

Chris Gimenez was Santana's backup and could see time there, but he's more of a utility player who is well-schooled in the art of catching. Marson can handle a staff extremely well. He has the makings of a hitter who can produce an acceptable average, but he hasn't come close to proving it in the bigs.

Outfielders

Peter Bourjos, OF, Los Angeles Angels of Anaheim

The Angels called up one of their top prospects yesterday and inserted him in center field. That's Torii Hunter territory; the vet agreed to move to right to accommodate the youngster. Bobby Abreu also moved, from right to left.

Bourjos is an accomplished minor league hitter (.293 lifetime average) who's a thief at heart (109 swipes in his past two and a half seasons). His 2010 power breakthrough (13 homers for Triple-A Salt Lake) is likelier a product of PCL hitting environments. His peripherals aren't incredibly saber-friendly, but he's reportedly improving his approach.

Bourjos may have trouble hitting better than .250 in his initial exposure to major league pitching, but he's one of the fastest players in baseball. His speed will help him make that up, a little. The Halos are looking for a shot in the arm. They wouldn't ask two mainstays to change positions if it wasn't a long-term trial; they'd just give one a night off.
