Philadelphia Phillies ace Zack Wheeler has opted out of the 2025 MLB All-Star Game to focus on resting and preparing for the upcoming second half of the season. With a strong 9-3 record over 18 games, Wheeler has established himself as a dominant force, recording 148 strikeouts, the second highest in the majors. His 2.17 ERA places him among the top pitchers this season. As Wheeler steps away, Adrian Morejon of the San Diego Padres will replace him in the All-Star roster. Wheeler's next start is scheduled against the Padres on July 12.
