SAN DIEGO -- The Padres finalized their 25-man roster Sunday morning, deciding on No. 6 prospect Colin Rea for their final rotation spot and opting to go with eight relievers instead of a backup utility infielder.
The decision to carry an extra reliever means both left-hander Ryan Buchter and Rule 5 right-hander Josh Martin join Rea on the Opening Day roster.
In the wake of the final roster decisions, left-hander Robbie Erlin, outfielder Jose Pirela and infielder Alexi Amarista were all optioned to Triple-A El Paso.
