The Boston Red Sox have struggled in May, going 10-16 and falling to 27-31, 9.5 games behind the Yankees. While catcher Carlos Narvaez and designated hitter Rafael Devers have been standout performers, rookie Kristian Campbell has hit a rough patch, batting just .120 in May, raising questions about his future. With other players like Trevor Story and Connor Wong also underperforming, the Red Sox face challenges in turning their season around as June approaches.
