Tolle is new to a postseason start, though he has been on this stage before. He appeared briefly in last year’s Wild Card series, retiring one Yankees hitter in relief. His rise this season changed the assignment: he began the year outside Boston’s rotation, was called up for good in April and finished as its Game 1 choice. At 23 years and 332 days, MLB says he will be the third-youngest Red Sox pitcher to open a playoff run.
The series also gives Boston an immediate test of its offense and health. The Red Sox have reported uncertainty around Willson Contreras’s right hand and Mickey Gasper’s biceps; their status belongs to the final roster and lineup announcements, rather than any assumption about Tuesday’s starters. For now the pitching plan is set. Boston needs one win behind Tolle to move within a game of advancing, while a loss would put Gray into an elimination start Wednesday. Tolle discussed the assignment at the club’s Monday workout-day media session.
