I was going thru the transactions on MLB.COM and noticed the Padres have Outrighted Carlos Guevara to Triple-A. 

San Diego Padres

Outrighted OF Paul McAnulty and RHP Carlos Guevara to Triple-A Portland; Purchased the contract of OF Chip Ambres and also recalled INF Brian Myrow and LHP Joe Thatcher from Triple-A Portland; Placed RHP Brett Tomko on the 15-day disabled list, retroactive to July 1, with a right elbow strain.

As many of you know, Guevara was a Rule V Pick from the Reds Farm System last year, but struggled with an injury this year and posted a 1-0 record with a 5.84 ERA in 12.1 IP, allowing 2 HR, while striking out 11, and walking 9.  If I recall, his out pitch was a screwball.

Don't the Padres have to keep him all year on the 25-Man, or we get him back or a PTBNL??
