Since becoming the head coach in 1997, he has led the program to 13 20-win seasons and 13 consecutive NCAA Tournament appearances. Under his guidance in 2009, the Blue Devils reached the pinnacle of success as they captured the program's first NCAA Championship. Over the past 17 years at the helm of the program, he has led Duke to a 367-83 (.815) overall record and a 124-23 (.843) ACC mark, while advancing to the NCAA Semifinals eight times, NCAA Championship match twice and notching ACC Tournament Championships on eight occasions.
In 2012, Ashworth led Duke to a 29-3 (.906) record overall to become the ACC's all-time wins leader. Duke finished 11-0 in the ACC to become the first team in ACC history to have a perfect 11-0 record and win the ACC tournament in the same season. The team's 29 wins tied the 2009 national championship team for the second most in a season, while the Blue Devils also tied the 2009 team for the second-longest winning streak in program history with 18 straight victories. The 2012 campaign was the fifth straight 20-win season for the program, and the eighth time that the Blue Devils reached the 25-win plateau during Ashworth's tenure. The Blue Devils reached the NCAA semifinals for the eighth time in program history, and finished the season listed No. 3 in the Intercollegiate Tennis Association's final team rankings for the second consecutive year. The Blue Devils ended the season with six players ranked in the final ITA poll, four players named to the All-ACC team, and freshman Beatrice Capra honored as ACC Player of the Year.
The 2011 season saw Ashworth lead the program to its third straight quarterfinal appearance and the 16th overall in the NCAA Championships. The Blue Devils finished the season ranked No. 3, and had all six singles players and four teams of doubles in the final ITA rankings. Nadine Fahoum, Rachel Kahan, Ellah Nze and Reka Zsilinszka were All-ACC selections. Kahan was named ACC Freshman of the Year, while Nze and Zsilinszka each concluded their college careers with four consecutive All-ACC honors.
In 2010, Ashworth reached another milestone in his career as he garnered his 300th career victory when the Blue Devils blanked ACC foe NC State 7-0 on Feb. 25, 2010. Duke had yet another successful season in 2010, posting a 22-8 overall record and advancing to the NCAA Tournament quarterfinals for the ninth time under Ashworth and for the third time since 2006.
Just a week after capturing the team title, Ashworth helped mentor Blue Devil freshman Mallory Cecil to the NCAA Individual Singles Championship and a No. 1 national ranking. Under his watch, Cecil, Ellah Nze and Reka Zsilinszka all captured All-America honors for singles, while Cecil was named the ITA Player of the Year. Duke was equally impressive in the classroom in 2008-09, landing an ACC-best five players on the All-ACC Academic team.
In addition to the NCAA title, the Blue Devils captured a share of the ACC regular season title and won the ACC Tournament Championship in thrilling fashion. Five Blue Devils earned at-large bids to the NCAA Tournament and seven players were ranked in the final ITA national poll.
Ashworth has coached 23 different All-ACC selections and 21 different All-America honorees, two national champions and four collegiate grand slam champions during his stint with the Blue Devils. That list that includes four-time All-America and 1998 NCAA singles national champion, Vanessa Webb, who is Duke tennis’ only Honda Award winner and Olympian. Four of Duke’s ACC Rookie of the Year honorees has come under his tenure, as well as two ITA National Rookies of the Year. Ashworth was named both ACC Coach of the Year and Wilson/ITA Southeast Region Coach of the Year on two occasions (2001, 2003).
A 1994 speech communication graduate of Maryland, Ashworth was a four-year letterwinner for the Terrapins and served as a captain of the team his junior and senior years.
