Cora also noted that the team effectively executed their coaches' strategy, even while facing challenges with hitting in critical situations.

Mayer's impressive performance, alongside fellow prospects, signals a hopeful future for the Red Sox as they continue to strive for playoff contention.

Mayer credited his father, Enrique, for instilling in him the importance of playing the game correctly and holding him accountable during training.

Veteran Rafael Devers acknowledged the impact of rookies like Mayer and Anthony, emphasizing their contributions to the team's performance.

Despite his success, Giolito mentioned that Mayer still has work to do to reach the 20-home run milestone this season.
