DETROIT -- Jim Leyland doesn't believe momentum exists in baseball because your next pitcher will dictate whether you win or lose.
Detroit has won five straight, matching a season high.
"I definitely feel like there's some momentum," Verlander said. "We're pitching well, hitting well and playing good defense. That's how you get on streaks.
"Earlier in the year, we weren't pitching well, but we were hitting. Then once the pitchers got locked in, we hit a lull at the plate."
Verlander (8-4) gave up three runs -- two on solo homers -- seven hits and no walks over eight innings.
"Solo home runs are not the end of the world," Detroit manager Jim Leyland said. "Three-run homers hurt."
The Nationals found that out.
After pulling within two runs in the sixth, Boesch broke the game open in the next inning with a blast off Livan Hernandez that soared deep into the right-field seats.
Washington manager Jim Riggleman blamed himself for not taking out Hernandez sooner.
"I gave him too much rope there," Riggleman said. "We had it down to two runs, and I was hoping he could get through that inning, and we could score some more and get him a win, or at least a no-decision. It didn't pay off."
Hernandez (5-4) allowed eight runs, doubling his season high, seven hits and a season-high six walks in 6 2/3 innings.
"He doesn't have the same stuff than he did when I had him, but he's a very, very good pitcher," said Leyland, who managed Hernandez during the Florida Marlins' 1997 championship season. "I've never seen him like that control-wise. It was strange to see him walk those guys."
"I felt very good in the first inning, but nothing worked in the second," Hernandez said. "I guess that happens to every pitcher sometimes. You get on the mound and you suddenly can't throw a strike. The slider was going outside, the curve was going inside and the sinker was dropping too low."
The Tigers added a run in the third on Boesch's run-scoring single, and the rookie finished with four RBIs, matching a season high.
"It's always tough to put a rally together against Verlander," Riggleman said. "We got a couple solo homers, but he's got too many weapons to ever expect to put together a sustained rally against him.
