Dustin Brown makes his first career start Sunday as he will catch Jon Lester in Sunday’s four-game series finale with the Texas Rangers. Mike Cameron also bats sixth and plays center field for the Red Sox.

Brown was called up on Saturday and came into catch the ninth inning after Ryan Shealy pinch-hit for Kevin Cash in the eighth. Brown popped out to short in the 10th in his only plate appearance of the night.

Meanwhile, Vladimir Guerrero makes his first career regular season start in left field, allowing slugger Josh Hamilton to DH for manager Ron Washington. Guerrero has appeared in left field only twice in the majors, in the 2000 and 2006 All-Star Games.
