MLB.com's Bill Ladson announced via Twitter this morning that the Washington Nationals had agreed on a minor league deal with another veteran left-hander who'll head down to Florida and compete for a spot in the Nats' bullpen.

Ohman, 35, pitched for the White Sox in 2012 in his 10th major league season, going (0-2) with a 6.41 ERA, 6.28 FIP, five walks (1.69 BB/9) and 13 Ks in 32 games and 26.2 IP before he was released in early July. Ohman was in his second season with Chicago (on a 2-year/$4M dollar deal) after he went (1-3) with a 4.22 ERA, 4.13 FIP, 17 walks (2.87 BB/9) and 54 Ks (9.11 K/9) in 59 games and 53.1 IP in 2011. The veteran lefty signed with Cincinnati a few weeks after he was released by the White Sox last summer and he made 15 appearances for the Reds' Triple-A affiliate but was never called up to the majors.
