New York Yankees outfielder Giancarlo Stanton isn't in the lineup for Game 2 of the ALCS against the Houston Astros due to a right quadriceps injury, manager Aaron Boone told reporters prior to Sunday's contest, according to ESPN's Marly Rivera.
Stanton suffered the strain while running down the line after singling in his first at-bat during Saturday's Game 1. He was able to stay in the game, and the four-time All-Star homered off Zack Greinke two innings before being lifted for defensive purposes. An MRI taken on Sunday revealed the injury.
The severity of the strain isn't clear yet, and neither is Stanton's status for the remainder of the ALCS.
Boone said Stanton will be available to pinch hit during Sunday's game in an "emergency situation," according to Rivera. He also stressed the team isn't ready to remove the slugger from the ALCS roster yet.
"We're hoping the off day helps and (the strain) declares itself more," Boone said, according to Bryan Hoch of MLB.com.
If the Yankees have to replace Stanton during the ALCS, he'll become ineligible to participate in the World Series if the club advances.
The 29-year-old former MVP played in just 18 regular-season games this year due to a litany of injuries. He started each of the Yankees' first four playoff contests, going 3-for-10 hitting with four walks and two RBIs.
Cameron Maybin is the Game 2 starter in place of Stanton, hitting eighth and playing left field.
The Yankees are looking to take a commanding 2-0 series lead on Houston after winning 7-0 on Saturday.
