The Nationals placed setup man Joe Biemel on the 15-day disabled list today after he hurt his hip flexor last night. As a result the Nationals will recall reliever Saul Rivera only a day after sending him down to the minors.
The temporary loss of Biemel will be felt immediately for the Nats who have come to rely on him as the only reliable arm in the pen so far in 2009. In eight appearances this year Biemel boasts a 1.23 ERA with four holds.
Rivera had been sent down in a move on Sunday night that was designed to completely reformat the Nationals bullpen. Back in Washington he will have a short timeframe to prove that he deserves to stay there.
