Matt Wise and Mickey Callaway
Wise and Callaway were much less impactful than Percival, Salmon, and Anderson during the 2002 season, but both pitchers had a cup of coffee with the Angels that season. Callaway posted 34.1 innings, and Wise 8.1. Callaway pitched 38.1 innings for the Angels in 2003, before making his way to the Rangers. Wise did not pitch in 2003 due to an injury, and picked up with the Brewers in 2004.
Callaway was the Indian's pitching coach for five seasons, before being hired as the Mets' manager for two. After he was fired, the Angels hired him as their pitching coach in October. A few months later, a detailed report of Callaway's sexual harassment came out and he was promptly fired before the season began. They promoted Wise as his replacement.
Wise served as the Angels' pitching coach for four seasons, from 2020-2023, and oversaw the development of many key pitchers in the organization. First and foremost, he was Ohtani's pitching coach, but also current pitchers like Patrick Sandoval, Reid Detmers, and Tyler Anderson. Wise currently serves as the White Sox bullpen coach.
