With the Red Sox calling up Mookie Betts from Pawtucket, they have optioned right-hander Rubby De La Rosa to the PawSox to make room for him on the roster.
Betts arrived in New York, where the Red Sox faced the Yankees on Saturday night. He was not in the starting lineup. Fox Sports' Ken Rosenthal reported that Betts will start in right field in the series finale on Sunday night.
De La Rosa, 25, was impressive in his five starts since joining the Sox rotation. He had a 2.51 ERA with 30 strikeouts in eight walks in 32 1/3 innings. With Clay Buchholz returning to the rotation and Felix Doubront in the bullpen, the thinking apparently is that De La Rosa will give the Red Sox a major-league ready starter at Pawtucket when he's needed back with Boston.
Betts, 21, selected out of high school in 2011, started the season at Double-A Portland before earning a promotion to Pawtucket earlier this month.
The right-handed hitting Betts hit .322 with an .869 OPS at Pawtucket. While in Portland, he hit .355 in 54 games with 6 homers and 34 RBI. Between the two stops, he's stolen 29 bases in 34 attempts.
A natural infielder blocked at second base by Dustin Pedroia, Betts played the outfield at Pawtucket. First, he was used in center and more recently the Sox had him in right field in Pawtucket after right fielder Shane Victorino's rehab was halted. Victorino's return now could be weeks away, speeding up the arrival of Betts.
