Doug Slaten Rumors

Nationals DFA Doug Slaten

The Nationals designated Doug Slaten for assignment to make room for new acquisition Adam Kennedy, according to Chico Harlan of the Washington Post (via Twitter). The Nationals picked the 30-year-old Slaten up off waivers from the D'Backs in November. 

The lefty pitched just 6.1 innings in the majors last year. He pitched more in 2008, logging 32.1 innings for the D'Backs with 3.9 BB/9 allowed and 5.6 K/9. Slaten added 43.2 Triple A innings last year and his rates were better in the minors. He walked just 3.1 BB/9 with 8.1 K/9 for a 3.09 ERA. 

It has been a busy day for the Nats, who agreed to sign Chien-Ming Wang.

Petit, Slaten Claimed Off Waivers

According to Nick Piecoro of the Arizona Republic, right-hander Yusmeiro Petit and left-hander Doug Slaten have been claimed off waivers.

Petit, 24, was scooped up by the Mariners.  He went 3-10 with a 5.82 ERA, 1.52 WHIP and 74/34 K/BB ratio in 17 starts (89 2/3 innings) this season with the D'Backs.  As Piecoro notes, Petit has allowed 1.96 HR/9 through 229 1/3 major league innings, tied for the worst rate in MLB history.

Slaten, who turns 30 in February, was claimed by the Nationals.  He allowed five earned runs and 11 total baserunners in 6 1/3 innings with the Diamondbacks in '09, but posted a 3.09 ERA and a 40/15 K/BB ratio in 43 2/3 innings at Triple-A Reno.  He hasn't been the same since undergoing knee surgery at the end of 2007.
