The Washington Nationals designated reliever Brad Lidge for assignment on Sunday.

Lidge went 0-1 with two saves and a 9.64 earned run average in 11 appearances this season with the Nationals.

The 35-year-old Lidge signed a one-year contract with Washington in the offseason after spending the previous four years with the Phillies.

The right-hander helped Philadelphia to a World Series title in 2008. He posted a 1.95 ERA and converted all 48 of his save opportunities during the regular season and playoffs.

However, the following season, Lidge blew 11 saves while recording an 0-8 record and 7.21 ERA. He rebounded in 2010, but has been limited since because of elbow and shoulder injuries.

Originally selected in the first round of the 1998 draft by Houston, Lidge has a 26-32 record with a 3.54 ERA in 603 career games (one start) with the Astros, Phillies and Nationals. The two-time All-Star has converted 225-of-270 save opportunities.

Washington also reinstated pitcher Ryan Mattheus from the 15-day disabled list on Sunday.

Mattheus missed the last 24 games with a plantar fascia strain in his left foot. He is 2-1 with a 2.25 ERA in 19 relief appearances with Washington this year.
