Gallen will be available for Game 7 of the NLCS against the Phillies on Tuesday, Matt Breen of The Philadelphia Inquirer reports.
Gallen took the mound for Saturday's Game 5, allowing four runs on six hits and two walks while fanning one over six innings. Despite tossing 93 pitches only a few days ago, he'll be ready to go in relief if called upon with a chance to go to the World Series on the line.
