Pivetta will likely start Game 4 of the ALDS against the Rays on Monday, Alex Speier of The Boston Globe reports.
Pivetta served as a long reliever in Thursday's Game 1 loss and allowed three runs on four hits and two walks while striking out four in 4.2 innings. Manager Alex Cora said that Eduardo Rodriguez and Chris Sale are also candidates to start Monday, but Pivetta is the most likely option.
