Keith Zuniga, the University of Hawaii's associate head coach and the architect of the Rainbow Warriors' recent pitching surge, is leaving Honolulu to become USC's pitching coach, according to local reports. The move sends one of college baseball's most buzzed-about young pitching minds to Los Angeles and adds another twist to an already busy offseason of staff changes for Hawaii. The clock is ticking too, with the Rainbow Warriors gearing up for full Mountain West membership on July 1 and now scrambling to find replacements.
Local reporting and reaction
According to the Honolulu Star-Advertiser, Zuniga will take over control of USC's pitching staff, filling the vacancy that opened when former Trojans pitching coach Sean Allen left the program. The Star-Advertiser report includes reactions from inside the Rainbow Warriors' clubhouse that underline how central Zuniga has been to Hawaii's rise on the mound.
Pitcher Isaiah Magdaleno told the Star-Advertiser that Zuniga is a "great coach, great guy" who "deserves it," adding that Zuniga's Southern California roots and relationships should make for a smooth transition into the Trojans dugout.
How he built Hawaii's staff
Under Zuniga, Hawaii's pitching staff quietly turned into one of the stingiest in the country. The Rainbow Warriors finished the regular season third nationally in team ERA and were one of only four Division I programs to crack the top 20 in ERA in each of Zuniga's three seasons, according to Hawai'i Athletics. That run featured a low opponent batting average and multiple shutouts that let the 'Bows punch above their weight in conference play.
Why USC made the move
The opening at USC was created when the Trojans' pitching coach accepted a head coaching job elsewhere. USC Athletics confirmed Sean Allen's move to Lamar in a June 2 release and credited him with helping build an elite staff, highlighting the program's national pitching numbers during his tenure. Zuniga steps into that role with a resume that features development of both frontline weekend starters and the depth arms that carry a staff through a long season.
Timing and what comes next for Hawaii
Zuniga's departure is not the only change in the Hawaii dugout. Head coach Rich Hill confirmed earlier this week that longtime hitting coach Dave Nakama is also moving on, as reported by Yahoo Sports. The staff turnover lands right as Hawai'i prepares to shift conferences. The Rainbow Warriors are scheduled to move from the Big West to the Mountain West on July 1, 2026, according to the University of Hawaiʻi, which means a new slate of conference opponents will arrive just as the program reshuffles its coaching staff.
What to watch
Hawaii now has a narrow window to find coaches who can sustain, and ideally extend, the pitching production Zuniga helped build. At the same time, USC will expect Zuniga to bring that same magic to a Pac-12 and Power 4 recruiting battlefield that prizes elite arms. Zuniga's ties to USA Baseball's development programs, noted in his profile on USA Baseball, could bolster USC's access to top pitching prospects. Rainbow Warriors fans, meanwhile, will be watching closely to see who Hill taps to guide both the mound and the lineup as the program heads into a new conference era.
