The Phillies selected right-handed pitcher Kevin Munson with the fourth pick in Thursday's Rule 5 draft.
Munson, 24, is a former fourth-round pick of the Diamondbacks. He's 11-12 with a 4.42 ERA in 154 minor-league appearances, all in relief. He's struck out 225 batters in 181 1/3 innings.
Munson, an Edison, N.J. native, split time last season at Arizona's Double A and Triple A affiliates, earning a trip to the Southern League All-Star Game.
Per MLB rules, Munson must remain on the Phillies' active roster all season (barring injury) or be offered back to the Diamondbacks for $25,000.
The Phils also lost a player in the major-league portion of the Rule 5 draft. Pitcher Seth Rosin, acquired from the Giants as part of the Hunter Pence trade at the 2012 deadline, was selected by the Mets. New York then quickly shipped the 25-year-old to the Dodgers.
Rosin went 9-6 with a 4.33 ERA at Double A Reading last season.
The loss of Rosin means Tommy Joseph is now the lone remaining piece left from the Pence trade. Nate Schierholtz was non-tendered by the Phillies last winter.
The Phils also lost shortstop Jonathan Roof to the Red Sox in the Triple A portion of the Rule 5 draft.
