Blake Treinen makes his third start of the season, second since taking injured Gio Gonzalez’s spot in the lineup. In his last start, Treinen allowed two runs on four hits, walked five and struck out four over 5 2/3 innings. Overall this season, the hard-throwing right-hander has been impressive, allowing three earned runs over 17 1/3 innings, good for a 1.56 ERA. Henderson Alvarez (2-3, 3.21 ERA) starts for the Marlins. The lineups are here. As always, talk about the game in the comments section.

UPDATE, 6:41 p.m.: The Nationals announced that the start of the game will be delayed due to the weather. The tarp is on the field, it is raining and the forecast isn’t promising. More announcements to come.
