T.R. Sullivan's Sunday morning blog looks at the various camp battles...
He seems to have David Murphy pushing Marlon Byrd into more of a 4th outfielder role, Gerald Laird beating out Jarrod Saltalamacchia, Jason Botts starting the season in the majors with Kevin Mench at DH, and Sidney Ponson getting a look as the 5th starter ahead of Luis Mendoza.
He also has Wes Littleton, Jamey Wright, and Scott Feldman winning the final 3 slots in the bullpen, although with no 5th starter needed until 4/12, he acknowledges someone else will probably stick around in the pen as well...
