After six innings of play in Washington, the Nats and Cards are still tied, 1-1. The Nationals took the lead in the bottom of the second when Adam LaRoche hit a lead-off home run, and the Cardinals tied it in the third when Pete Kozma scored on a Carlos Beltran sacrifice fly.
Ross Detwiler has now thrown 104 pitches in his six innings of work. He's allowed three hits, and given up three free passes while striking out two batters. The only run given up by Detwiler is unearned, as Ian Desmond booted a ball in the third inning that left the Cards in position to score.
Kyle Lohse has been a bit more economical with his pitches than Detwiler, he's needed just 77 pitches to get through six innings. Lohse has allowed only two hits and one earned run, and is yet to issue a walk. He's struck out five Nats' batters in Game 4.
Detwiler will be replaced by Jordan Zimmermann for the seventh inning.
