Pivetta will start Game 4 of the ALCS against the Astros on Tuesday if he isn't needed out of the bullpen Monday, Jen McCaffrey of The Athletic reports.
Every postseason game has at least a bit of an all-hands-on-deck element to it, so it's possible Pivetta will be used Monday, especially if the game goes to extra innings. With games scheduled on three consecutive days, however, the Red Sox would prefer to have the Canadian righty handle multiple innings at the start of Tuesday's contest. Pivetta has pitched well in his first taste of postseason action this year, allowing three runs in 8.2 innings while striking out 11 batters.
