The New York Yankees committed four errors, leading to six unearned runs, in a 6-3 loss to the Boston Red Sox on Thursday night at Fenway Park. The sloppiness proved costly, overshadowing the Yankees' early offensive efforts and surrendering the series opener.

The turning point came in the fifth inning when pitcher Cam Schlittler's outing unraveled. After Amed Rosario's fielding error allowed the first unearned run to score, breaking a 2-2 tie, former Yankees prospect Caleb Durbin hit a two-run home run. Schlittler exited the game having allowed four unearned runs in the inning, with the Red Sox ultimately scoring six unearned runs on the night.

Rosario's error came on a ground ball that went through his legs instead of allowing for a potential inning-ending double play. This miscue allowed the first of the four unearned runs to score. Jarren Duran added to the lead with a sacrifice fly, and Durbin's blast over the Green Monster gave Boston a 4-2 advantage.

The Yankees attempted a comeback in the seventh inning. Paul Goldschmidt, after a lengthy at-bat against former Yankees reliever Greg Weissert, hit a chopper that allowed Jazz Chisholm Jr. to score from third, narrowing the deficit to 4-3. However, the rally stalled when Ben Rice grounded out.

Boston extended its lead in the ninth inning with two more insurance runs, capitalizing on a bobbled sacrifice bunt and a wide throw on a potential inning-ending double play.

The game began positively for the Yankees. Goldschmidt led off the first inning with a double and later scored on a single by Jasson Domínguez. José Caballero then extended the lead in the fourth with his eighth home run of the year, a solo shot just over the Monster.

Schlittler, despite navigating through trouble in the early innings, stranded runners in the first, second, and fourth. He struck out nine batters over five innings but ultimately faltered in the pivotal fifth. The Yankees also called on Aroldis Chapman to close out the game in the ninth. He loaded the bases with two outs before securing the final out.
