Strained oblique sends Nats' Stephen Strasburg back to DL

Strasburg exits early with tightness in side

Nationals pitcher Stephen Strasburg talks about leaving Saturday's game in the fourth inning with tightness in his side.

The Washington Nationals placed starter Stephen Strasburg on the 15-day disabled list Sunday with a left oblique strain.

The 26-year-old right-hander left Saturday's game against the San Francisco Giants in the fourth inning after experiencing tightness in his left side.

Strasburg allowed one hit over 3 2/3 scoreless innings in his third start since coming off the disabled list. He missed nearly four weeks due to neck tightness.

Though only 5-5 with a 5.16 ERA in 2015, in his previous two starts since returning from his earlier DL stint, Strasburg went 2-0 with a 1.50 ERA and 15 strikeouts. He dominated the Giants before leaving.

The Nats called up right-hander Taylor Jordan from Triple-A Syracuse to replace Strasburg on the roster.
