Danielle O'Toole-Trejo

CSUF's pitching staff excelled under the tutelage of O'Toole-Trejo in 2023, led by Big West Pitcher of the Year and NFCA All-West Region honoree Myka Sutherlin (1.64 ERA, 272 strikeouts) and Haley Rainey (1.53 ERA, 87 strikeouts).

A native of Upland and referred to as "Tooly", O'Toole-Trejo retired from playing competitive softball in 2022 while being widely regarded as one of the top pitchers in the world, earning the title of inaugural Athletes Unlimited Softball Champion in the summer of 2022 with 1,436 points. She was selected to Team USA in January of 2017 and helped lead the team to a silver medal at the International Cup and a gold medal at the World Cup of Softball.

Prior to Cal State Fullerton, she spent two seasons (2018 and 2019) as the pitching coach for the San Diego Toreros softball program. In addition, O'Toole-Trejo conducts instructional clinics that cover both mental and physical training.

O'Toole-Trejo boasts a lengthy resume of softball and academic accomplishments during her collegiate career at Arizona and San Diego State. She earned NFCA All-America First Team honors in 2017 and was a three-time NFCA All-West Region selection.

Even with Arizona's rich softball tradition, O'Toole-Trejo goes down as one of the best pitchers in program history. In 2017 she became UA's first NFCA First Team All-American pitcher since Kenzie Fowler in 2010. She was named the 2017 Pac-12 Pitcher of the Year, the first Wildcat to win the award since Alicia Hollowell in 2004, and was selected as one of 10 Finalists for USA Softball Player of the Year. O'Toole-Trejo was a First Team all-conference and all-region performer as well as a member of the All-Defensive team.

She posted a 30-5 record with a Pac-12-best 1.21 ERA and struck out 210 batters in 219.0 innings while allowing two or fewer runs in 29 of her 34 starts on the season. O'Toole-Trejo finished in the top three in the Pac-12 in every major pitching category: 1st with a 1.21 ERA (9th in NCAA), 2nd with 210 strikeouts (28th in NCAA), 2nd with a .184 opponent batting average, 3rd with 219.0 innings pitched, 2nd with 30 victories (5th in NCAA), 2nd with 35 games started and 1st with nine shutouts (17th in NCAA).

O'Toole-Trejo also earned Mountain West Pitcher of the Year honors in 2014 and Mountain West Freshman of the Year recognition in 2013 while with San Diego State. She also excelled in the classroom and was a 2017 Pac-12 All-Academic selection before graduating in the spring of 2017 with a Bachelor's of Science in care, health and society.
