What happened: Former-player committees select one recipient from each club for passion, desire and work ethic on and off the field. Antonacci is among 30 team honorees.
Why it matters: The honor puts the 23-year-old rookie in contention for the overall award. His selection follows an April major-league debut.
By the numbers: Antonacci entered August with a .293 average, five home runs, 25 RBIs, 12 stolen bases and an .803 OPS in 249 at-bats.
What to watch: Fans and baseball alumni will vote on the overall winner after the season.
