Burnett, who has not pitched since Sept. 2 due to nerve irritation in his left elbow, threw a bullpen session Monday and was set to play catch on Tuesday. Burnett had said he hoped to be available for the second game of the series against the Mets, but manager Davey Johnson said Tuesday that the series finale on Wednesday was a more likely scenario.
"Sean wanted to be available today," Johnson said before Tuesday's game. "But we're gonna watch him play catch, and I won't use him today. I'll give him another day off. If everything goes good, he'd be available tomorrow."
Burnett leads all Nationals pitchers with 61 appearances, with a 2.49 ERA through 50 2/3 innings. He has struck out 50 batters.
