Diaz will be in his third season in Loretto in the fall of 2026.

Emma Sawich highlighted the 2025 season after she was named to the All-NEC second team and finished the regular season ranking second in NCAA Division I in saves (136).

Diaz's first year as head coach saw the Red Flash double their win total from the previous season. The Red Flash went 6-9-3 and 4-5-1 in the NEC. Diaz led the Red Flash to a winning record on the road at 5-4-1.

Diaz guided the Red Flash to their best defensive season since 2012. Allowed just 22 goals (1.22 goals against average) and had the best goals against average in the conference until the final matchday.

Diaz's first season in the Saint Francis dugout saw Lauren Pyle earn an All-NEC first-team selection and Rory Schaeffer named All-NEC second-team selection.

Under Diaz's tutelage, Alyssa Mella scored the most goals by a Saint Francis freshman since 2018 and Pyle score the third most goals by a Saint Francis player in a season since 2019.

Diaz helped Sawich lead the conference in save percentage at .824 and make the most saves in a season by a Red Flash goalkeeper (98) since 2018. Sawich finished tied for 53rd in the nation for save percentage, tied for 30th in the nation in saves and saves per game (5.44)

Diaz's squad totaled 18 NEC weekly awards and seven combined Player of the Week, Defensive Player of the Week and Rookie of the Week nods.
