Outfielder Giancarlo Stanton was left out of the Yankees' starting lineup for Game 2 of the American League Champion Series against the Houston Astros after suffering a right quad strain in his team's Game 1 win.

Manager Aaron Boone told reporters the injury occurred during Stanton's second-inning infield hit, in his first at-bat of Saturday night's series opener. He remained in the game and later homered.

Boone said he underwent an MRI, which revealed the strain, but remains an option to pinch hit Sunday.
