The Washington Nationals have agreed to a minor-league deal with Nate Schierholtz and assigned the veteran outfielder to Triple-A Syracuse.

General manager Mike Rizzo made the announcement before Monday night's game against Arizona.

The 30-year-old Schierholtz is a .254 career hitter with 51 home runs and 224 RBI in 776 games. Last season with the Cubs, he hit .251 and established career highs in home runs (21), RBIs (68) and runs scored (56).

Schierholtz batted .192 with six homers in 99 games with Chicago this season before he was designated for assignment Aug. 6.

Schierholtz could give NL East-leading Washington an experienced lefty bat off the bench when rosters expand in September, or sooner. Lefty-hitting outfielder Nate McLouth is currently on the 15-day disabled list with right shoulder inflammation.
