Steve Herdoiza was a four-year letterwinner, compiling a 118-49 career record. In 1989, Herdoiza was the Big Ten singles champion and a year later helped the Wildcats win their first Big Ten team title in 27 years.
A teammate of Todd Martin on Northwestern's 1990 Big Ten championship team, Herdoiza earned All-America honors for his play. During the 1990 season, Herdoiza ended the year ranked fourth in the Region IV singles and advanced to the quarterfinals of the NCAA Championships, defeating the defending national champion along the way. He ended his career a four-time All-Big Ten selection and earned Academic All-Big Ten honors in 1989 and 1990.
In 1988, Herdoiza was crowned the Region IV champion and the following year played No. 1 singles ahead of Martin. In 1991, serving as an assistant under former head coach Paul Torricelli, he was awarded the Vandy Christie Award for his outstanding loyalty and dedication to Northwestern tennis.
As a player, Herdoiza is second and fourth (twice) on NU's single-season wins list, amassing 34 wins in 1988-89 and 33 in 1987-88 and 1989-90. His 1988-89 mark of 34-7 (.829) ranks as the second-best single-season winning percentage in NU history. He has the third highest career winning percentage (.707) as a singles player and is atop the career victories list with 118.
After graduating from Northwestern, Herdoiza went on to play on the professional tour for 4 1/2 years, achieving a world ranking in the 200's in 1995. During his collegiate and professional career, Herdoiza defeated eight former NCAA champions. A wrist injury in 1996 ended his career.
Herdoiza, who now devotes his time to teaching and coaching tennis, is married. He and his wife, Nicole, have two children.
