Narváez rose from unexpected backup to premium catcher for Boston, delivering a late-season power spike and outstanding defense as the primary backstop.

Narváez contributed with a ground-rule double that helped set up Duran’s inside-the-park highlight, anchoring the middle of Boston’s order with timely hitting and providing a run-scoring option in a productive Sox lineup.

Narváez emerged as a standout defensive catcher, leading the majors in caught stealing during the season's stretch and providing elite game-calling while the Red Sox navigated a hitting drop-off. His OPS+ sits around league-average, suggesting bat progression is possible but not guaranteed. The article stresses usage time and the burden of heavy workload, with his knee history hinting at fatigue risks that could impact performance as the season wears on.

Narvaez knee soreness keeps his lineup presence in question while the Red Sox rely on him as a cornerstone for late-season drive. His production has been a linchpin (.248 with nine homers, 33 RBIs). Boston signed Ali Sánchez to bolster catching depth as Narvaez returns from tests; Narvaez’s health will shape Boston’s postseason tempo and catching stability.

Rookie Carlos Narváez has emerged as a standout catcher for the Red Sox, showing excellent defensive skills and a .778 OPS. His performance puts pressure on Wong as the team considers its options.
