Fiorentino made an instant impact upon arrival last season, signing with the team in time for the second half opener after beginning the year at Triple-A Sacramento in the Oakland Athletics organization. With York, Fiorentino batted .311 in 66 games, which would have ranked fifth highest in the league with enough at-bats to qualify. Fiorentino batted everywhere in the order except the cleanup and ninth spots, and strung together three hitting streaks of 10 games or longer with the Revs, while batting .366 over his final 26 games played.

The 29-year-old was a third-round draft selection out of Florida Atlantic University by the Baltimore Orioles in 2004, and made his Major League debut at age 22 in just his second pro season, when he was called up from High-A. Fiorentino had hits in his first four at-bats at the big league level, and has totaled 58 Major League games over parts of four seasons with the Orioles and Athletics, batting a combined .270.
