The weather could be a factor tonight. As of 6:30, the tarp remains on the infield and neither starting pitcher has emerged to start his pregame warm-up. Both are ominous signs. If there is word of a delay, we’ll have it here.

When the game begins, the Nationals will try for their third straight win behind Stephen Strasburg against Wily Peralta, a right-hander with a 5.58 ERA. Since he came off the disabled list, Strasburg has allowed four earned runs in 19 innings over three starts. Talk about the game right here.
