Werth moved ahead of Ryan Zimmerman's 43-game streak set in 2009 and into a tie with Tim Raines (Expos) for the second most in franchise history. The franchise record is 46 consecutive games from Rusty Staub from 1969-70 with the Expos.
"Big congratulations to Jayson Werth, obviously it's been a run," left-hander Gio Gonzalez said. "That guy's unbelievable and deserves every bit of credit and tonight was about him."
