The Red Sox today claimed righthander Sandy Rosario off waivers from the Miami Marlins. To make room on the 40-man roster, outfielder Che-Hsuan Lin was designated for assignment.
The 27-year-old Rosario had been with the Marlins since 2004, when he was signed out of the Dominican Republic. He has 10 games of major league experience from 2010-12 and they did not go well. Over 7.2 innings, Rosario allowed 13 earned runs on 22 hits and three walks.
But Rosario pitched well in 31 minor league games this season. Over 31.2 innings, he had a 0.98 WHIP and a 1.99 ERA. He struck out 29 and had only three unintentional walks. Rosario has an above-average fastball.
His 403 strikeouts over 391 minor league innings speak to there being something to work with.
Lin, who was signed out of Taiwan in 2007, made his major league debut in 2012, going 3 for 12 in nine games. He is a career .256 hitter in the minors, his offensive skills well below his impressive ability to play the outfield.
Lin hit .247 for Triple A Pawtucket this season with 18 extra-base hits over 396 at-bats.
