Antonini has primarily been a starting pitcher in the minors and was exclusively so in 2010, posting a 4.32 ERA with 7.3 strikeouts per nine innings in 23 Double-A starts and a 5.11 ERA with 6.1 strikeouts per nine innings in six Triple-A starts.
Hu, who will be 27 in February, spent eight years in the Dodgers organization. Considered a defensive whiz, Hu's stock fell as he was unable to build upon a minor league campaign in 2007 when he had an on-base percentage of .364 and slugging percentage of .507 in Double-A and Triple-A combined. In his major league career, Hu has a .241 OBP and .283 slugging over 191 plate appearances.
Hu has the most times at-bat of any Taiwan-born player in major league history.
