Thompson claimed from Nats, Ledezma DFA
The Pirates claimed left-handed pitcher Aaron Thompson off waivers from the Nationals on Thursday.
Thompson, 23, made 27 starts during the 2010 season in the Nationals organization (26 at double-A, one at Triple-A). He went 5-13 with a 5.65 ERA. In 141.2 innings pitched he walked 56 and struck out 99.
In order to make room for Thompson on the 40-man roster, the Bucs designated Wil Ledezma for assignment. If he clears waivers, the Pirates have 10 days to trade, release or outright Ledezma to the minors.
Ledezma has already agreed to a contract with the Pirates for 2011, and the Bucs are hopeful he will accept the assignment to the minors and compete for a spot in the Pirates bullpen at Spring Training.
He appeared in 27 games for the Pirates during the 2010 season (19.2 innings). Ledezma 0-3 with a 6.86 ERA while striking out 22 and walking six.
