The Nationals tweaked their roster on Monday, releasing Roger Bernadina and trading for David DeJesus. They have 39 games left to make up 9 1/2 games on the Cincinnati Reds for the second wild-card spot. “I certainly have not given up on this season,” General Manager Mike Rizzo said before the game. Jordan Zimmermann starts (14-6, 3.02 ERA) starts, opposed by right-hander Jeff Samardzjia (6-11, 4.29 ERA). The lineups are here. As always, discuss the game here.
