Cam Schlittler produced one of the best starts in postseason history for a rookie, pitching eight scoreless innings with 12 strikeouts and 0 walks, helping the New York Yankees eliminate the Boston Red Sox in Game 3 of the AL Wild Card Series. For the starter, the win meant a lot more than a usual outing.Schlittler is a native of Walpole, Massachusetts, just over half an hour's drive from Boston. He's a resident of the city during the offseason and claimed ahead of his start that his family, who had been Red Sox fans initially, switched allegiances in support of him starting his Yankees career.However, most of the Schlittler family's friends and relatives, who are die-hard fans of the Red Sox, were seemingly "'bummed" after his stellar eight-inning shutout performance. The 24-year-old had a very honest answer for them during the Yankees' workout at Rogers Centre in Toronto ahead of their American Division Series."I told them that's exactly what was going to happen," Schlittler said. "They'll get over it. Hockey season is coming up, basketball season is coming up. So I'm sure they got other things to distract them."Boston's representatives in the NHL, the Boston Bruins, are in a phase of rebuilding. After eight consecutive Stanley Cup playoff appearances, the Bruins failed to qualify for the 2024-25 season, finishing with a 33-39-10 record.Meanwhile, their NBA counterparts, the Boston Celtics, have made it to two of the last four NBA Finals, winning one. Like the Red Sox, they were dumped out of the playoffs by a New York team, the Knicks, in the Conference Semifinals.Boston-New York rivalry boils over as fans harass Cam Schlittler's motherCam Schlittler also disclosed that his mother, Christine, was harassed on social media ahead of his start, which prompted her to make her X account private. While he didn't disclose the details of the hate comments she received, he expressed his disappointment, considering he was a part of the Red Sox fanbase."I think if it was a different fan base coming at them, I'd probably be a little bit more OK with it," Schlittler said. "I think it just being Boston was a little bit more disappointing."Despite all the social media hatred, Cam Schlittler has proven his talent on the field. He has solidified his place in the Yankees' rotation and will be expected to keep producing the same level of performance. He's slated to start Game 1 of the Division Series against the Toronto Blue Jays, if required.
