Red Sox pitcher Rubby De La Rosa worked as a reliever in his 11 appearances with the team last year, but will work throughout the spring as a starter. He made his first appearances Thursday against Boston College, tossing a pair of scoreless innings, with just one hit and two strikeouts in a 5-2 win.
De La Rosa is likely to return to the minors after spring training, where he posted a 4.26 ERA in 20 starts for Triple-A Pawtucket last season.
