Astros ace Dallas Keuchel, who is off to a 7-0 start this season, is headed to the DL with a pinched nerve in his neck, the team announced Saturday.

Keuchel, who won the Cy Young Award in 2015, has a 1.84 ERA, 54 strikeouts and has held opposing hitters to a .186 batting average in his nine starts this season. This is his first trip to the DL in his major league career.

The Astros expect Keuchel to miss only one start, and the DL move is retroactive to Wednesday.
