The Chicago Cubs acquired second baseman Miles Mastrobuoni from the Tampa Bay Rays on Tuesday in exchange for a Single-A pitcher, according to sources. Mastrobuoni can play both the infield and outfield. The 27-year-old made his major-league debut with the Rays this year and went 3-for-16 with a stolen base, a run scored and six strikeouts in his first eight big-league games. Down on the farm in 129 games for Triple-A Durham, the left-handed hitter batted a strong .300/.377/.469 with an .846 OPS, a career-high 16 home runs, 64 RBI, 92 runs scored and 23 stolen bases in 573 plate appearances for the Bulls. Mastrobuoni will likely compete for a utility role with Chicago in spring training next season.
