WASHINGTON (AP) — The Washington Nationals became the first team in the majors to clinch a playoff spot this season, winning the NL East on Sunday as Stephen Strasburg extended his scoreless streak to a franchise-record 34 innings in a 3-2 win over the Philadelphia Phillies.

Strasburg (13-4) threw two-hit ball for eight innings and struck out 10. He hasn't allowed a run since Aug. 19 at San Diego, his first start since coming off the disabled list with an elbow nerve impingement.
