NEW YORK — The last time Cam Schlittler took the mound against Boston with the Yankees’ season on the line, he turned a week of online hostility into one of the most memorable starts of the rivalry’s recent history.
Twelve months later, the setting looks familiar but the pitcher does not. Schlittler is no longer the rookie asked to rescue the Yankees in a winner-take-all game. He enters Tuesday night’s American League Wild Card Series opener at Yankee Stadium with a 14-6 record, a league-best 1.95 ERA and 239 strikeouts over 193 2/3 innings.
The Yankees chose him over Max Fried for Game 1, with Fried lined up for Game 2 and Gerrit Cole available for a deciding Game 3. Boston will counter with rookie left-hander Payton Tolle, who went 9-6 with a 3.03 ERA.
That decision made Schlittler central to another Yankees-Red Sox October. He grew up in Massachusetts, once rooted for Boston and has spent the past year trading words with parts of the Red Sox fan base.
Schlittler expects the Stadium atmosphere to match the stakes.
“It’s natural adrenaline. I expect it to be loud. It’s going to be an electric experience,” Schlittler said.
Last October, elimination stared at New York. This time, Aaron Boone is asking Schlittler to set the tone before the Yankees face that pressure. Boston remains the opponent that has produced his sharpest results and most combustible public moments.
He also carries a different profile into this matchup. The Yankees are handing Game 1 to a 25-year-old who went from seventh-round pick to first-time All-Star and Cy Young favorite in two seasons.
Schlittler brings the receipts back into the rivalry
The tension resurfaced before either club threw a postseason pitch.
Schlittler said he expects criticism from Boston fans to increase with the Yankees and Red Sox meeting again. He also suggested some of the attention around him has become useful content for people who discuss the rivalry.
“(You’d) think after last time, how much they were talking before, that they might be trying to quiet it down a little bit… Like, they use me for clicks or whatever it is, and I feel like I’ve done a good job of handling that so far.”
Schlittler said he is not searching for every insult, but he is not ignoring them either.
“I wouldn’t say I’m always on my phone looking for that stuff. At the same time, I don’t really live under a rock as well, so I find ways to use that to my advantage. I think I’m good at keeping receipts, and at the end of the day, I’m locked in to go in there tomorrow and do my job.”
Last October, Schlittler said members of his family were targeted online before Game 3. He answered with eight scoreless innings, 12 strikeouts and no walks in a 4-0 Yankees victory, then posted, “Drinking dat dirty water.”
The feud continued this season. Schlittler said he received death threats before his first Fenway start, sparred with Boston-based voices and deleted a personal jab after a podcast exchange. Boone has urged less social-media engagement.
Yankees have learned how to use Schlittler’s edge
The Yankees do not treat Schlittler’s appetite for slights as an accident.
Earlier this season, Chad Bohling, who oversees the club’s mental conditioning work, put a critical podcast clip into Schlittler’s pregame preparation. Schlittler responded with eight innings of one-run ball and eight strikeouts against the Rays.
Boone has seen the pattern.
“He feeds off that a little bit,” Boone said.
Schlittler has described it more plainly.
“I try to take things personally,” Schlittler said.
That approach predates the Yankees. At Northeastern, Schlittler used the attention surrounding NC State slugger Tommy White as fuel before throwing eight scoreless innings in 2022. Gerrit Cole later compared his manufactured motivation to Michael Jordan’s use of perceived slights.
Schlittler has also sought internal fuel. After a poor June 2 start against Cleveland, he spoke with Bohling, Cole, Fried and Yankees great Andy Pettitte about staying locked in while veteran starters dealt with injuries.
Boston has barely turned the feud into runs
The most important number in the back-and-forth is not attached to a social media post.
Schlittler has a 0.56 ERA across five career starts against Boston, including the postseason. He has allowed only two earned runs in 32 1/3 innings while striking out 39.
His 2026 regular-season splits shows how unusual that dominance has been. Boston scored two earned runs in 24 1/3 innings against Schlittler this season, a 0.74 ERA. Against everyone else, his ERA was approximately 2.13.
The Red Sox have therefore scored an earned run against him only once every 16-plus innings across their five meetings, including last October.
His three-fastball mix can reach 100 mph, but the Boston results go beyond velocity. The Yankees pitcher has repeatedly limited damage after multiple looks.
Game 1 puts the talk back on mound
The Yankees enter the postseason at 93-68, while Boston finished 87-74. New York earned the higher seed and home field for the best-of-three series.
Schlittler now must reproduce that dominance after Boston has had repeated looks at his repertoire. He has said his priority is helping the Yankees win their first World Series since 2009, not collecting individual awards.
He has made his view of the trash talk simple.
“If you can back it up, you can do whatever you want,” Schlittler said.
At 8 p.m. Tuesday, the Yankees will find out whether another round of receipts produces the same answer.
