Derek Lowe will be in the Texas Rangers' bullpen when the season opens on Sunday in Houston.

Manager Ron Washington said Lowe has made the team as a long reliever. The Rangers had to make a decision on Lowe today, as he had an out in his contract.

Lowe joins closer Joe Nathan, right-hander Jason Frasor and left-handers Michael Kirkman and Robbie Ross as known pieces in the bullpen, Washington said.

The final two spots are down to right-handers Josh Lindblom, Tanner Scheppers, Cory Burns and Coty Woods, as well as left-handers Nate Robertson and Joe Ortiz.
