The Boston Red Sox are not ruling out Chris Sale from pitching Game 4 of the ALDS if the situation arises.

Sale was shelled by Houston in Game 1 of the series and allowed seven runs on nine hits in five-plus innings as his Sox lost 8-2 to the Astros. Drew Pomeranz started Game 2 and Doug Fister is set to pitch in Game 3.

The Red Sox have last year’s Cy Young award winner Rick Porcello available for Game 4, but if they’re facing elimination, they might want to go with their ace.
