McArthur (elbow) began a throwing progression during the second half of the season and is on a bullpen schedule, per MLB.com.
McArthur missed the entire 2025 season while recovering from surgery to repair a fractured right elbow before suffering a setback during spring training. The right-hander ultimately underwent another procedure in late May due to recurring soreness and inflammation in the same elbow. It's a positive sign that McArthur has progressed to a throwing program, though he is running out of time to return to big-league action in 2026.
