Detroit outfielder Brennan Boesch has tweaked an oblique muscle in his right side and expects to miss a day or two of spring training.
Boesch says he hurt himself while swinging Saturday. Manager Jim Leyland said Boesch would not participate Sunday, but he had no other information on a timetable for Boesch's return.
The 27-year-old Boesch is in the middle of a crucial spring training camp. He was left off Detroit's postseason roster last year after hitting only .240, and although the Tigers signed him to a $2.3 million deal to avoid arbitration, his spot on the big league club isn't necessarily secure.
Boesch is competing for time in left field for the defending AL champions. Andy Dirks and Quintin Berry also are among the candidates to play there.
