WASHINGTON — By the time Stephen Strasburg settled down and looked like his dominant self, it was too late and his undefeated season was over.
Strasburg struck out 10 but allowed six runs and seven hits including two home runs, and the Nationals lost to the Dodgers 6-3 on Thursday. It was Strasburg's first loss since Sept. 9, ending a streak of 16 winning decisions.
"During the streak he was outstanding," manager Dusty Baker said. "You know every streak is going to end. That's the best streak I've ever seen I think. Now you just go back to the drawing board and start a new streak."
The All-Star right-hander allowed two- and three-run home runs to third baseman Justin Turner in the first and third innings and an RBI single to first baseman Adrian Gonzalez. After Turner's home run, Strasburg retired 12 of his final 13 batters.
"It was just a couple of pitches where I just didn't execute when I needed to, and I got beat on them," Strasburg said.
Strasburg (13-1) had the longest winning streak to begin a season among National League starters since the Giants' Rube Marquard went 18-0 in 1912.
The Nationals left 12 runners on base in losing to the Dodgers for the fifth time in six games this season.
