Gomez is listed hitting sixth Tuesday night. He missed the Astros' final regular-season series at Arizona because of a strained left chest muscle.
''He's bouncing around the clubhouse ready to play,'' Houston manager A.J. Hinch said. ''Obviously I have concerns just because he's not 100 percent. But in this moment, with this type of player, the importance of this game, this is the time to do it.''
''There's no doubt he can be an electrifying force in our lineup and on the field,'' Hinch said. ''And in this city and this ballpark, he'll have a ton of energy.''
