The 38-game streak is the longest of Werth's career and the longest in the Majors this season. The Nationals' record is 43, set by Ryan Zimmerman in 2009.
Werth got off to a slow start this season but turned things around in late May by recommitting to working counts and getting on base.
"I finally feel like myself," Werth said Friday. "I've always been an OBP guy. I kind of came into the season trying to be more aggressive. Everybody's always like, 'Why don't you be more aggressive, why don't you swing earlier in the count?' So I tried it, and I shouldn't have. So it just took me some time to get back to being me."
