The Washington Nationals reported yesterday that Michael Morse has what was diagnosed as a torn sheath and a bone bruise in his left wrist. The injury had become enough of a problem that the Nats' 30-year-old outfielder told skipper Davey Johnson he thought he was hurting the team and would have to sit and rest until it improved. The original plan was to have Morse take batting practice this afternoon to test the wrist, but reports from Atlanta his afternoon say that plan has been abandoned:

Michael Morse not taking BP today. Going to continue to rest his left wrist. Sounds like he'll miss the series. Davey said Tues more likely.

Morse won't take BP today, says he hasn't attempted to do much with L wrist yet. "I'll see how it feels tomorrow."

Davey says Morse is likely out until Tuesday. Davey not worried because he's got Bernadina and Moore. Unsaid: Up 8.5 games, too.

The Nationals' outfield minus Morse tonight will feature Roger Bernadina, Bryce Harper and Jayson Werth left-to-right as the Nats take on the Atlanta Braves in the first game of a three-game series that will wrap up the season series between the 1st and 2nd place teams in the NL East. Through 15 games, Washington holds a 10-5 advantage over Atlanta and the Nationals are 5-1 in Turner Field so far this year. Braves' starter Kris Medlen, however, is in the midst of a tremendous couple weeks on the mound.

Since joining the rotation, the 26-year-old, '06 10th Round pick is (7-0) with Atlanta (8-0) in his starts which have seen him post a 0.81 ERA over 55.2 IP in which he's allowed just 40 hits and six runs, five earned while walking seven (1.13 BB/9) and striking out 53 (8.57 K/9). Last time out against the Nats, Medlen threw 7.0 scoreless, holding Washington to seven hits and walk while striking out seven. Here's the lineup Medlen will face tonight in Atlanta:

Davey's Lineup-Fri @ ATL/G144: Werth rf, Harper cf, Zimmerman 3b, LaRoche 1b, Desmond ss, Espinosa 2b, Bernadina lf, Suzuki c, Detwiler lhp.
