Stephen Strasburg pitched into the eighth inning and Jayson Werth hit his second home run in two nights to lead the Washington Nationals past the Seattle Mariners 3-1 on Saturday.

Strasburg (11-10) went 7 2-3 innings and struck out eight, increasing his NL-leading total to 210. The right-hander also broke the Nationals' previous single-season record of 207 set by Gio Gonzalez two years ago.

Rafael Soriano worked around two ninth-inning singles to earn his 30th save in 35 attempts.

Dustin Ackley's home run chased Strasburg. Ackley was drafted No. 2 overall in 2009 — directly behind the Washington phenom.
