Duran was one of the most decorated pitchers in ECC history with three All-Conference First Team selections and two ECC Pitcher of the Year honors during his tenure with the Golden Lions.

His sophomore season in 2009 is arguably the best season by a pitcher in ECC history. After tossing a no-hitter with 14 strikeouts against Felician in his first start of the season, the righty ended up with a 10-2 record with two saves, 83 strikeouts, and a 1.30 earned run average over 89.2 innings. He led Division II with 4.52 hits allowed per game and his ERA was good for third in the country.

His efforts led Dowling to unprecedented heights, as well. Duran picked up a save with 2.1 scoreless innings in a 1-0 win over Adelphi that clinched the first and only NCAA East Region Championship in program history. Then in the Golden Lions' first-ever Division II World Series, Duran tossed a complete game three-hitter allowing only one unearned run in a 3-1 win over No. 1 nationally ranked UC San Diego.

Duran's outstanding season earned him a long list of honors including the first of his two ECC Pitcher of the Year awards and consensus East Region Pitcher of the Year honors. He was also a consensus First Team All-American and was named the Division II National Pitcher of the Year by two of three award publications (Daktronics and National Collegiate Baseball Writers Association).

His 2010 season was nearly as spectacular. He once again earned the ECC Pitcher of the Year award and consensus All-America honors (Second Team) after finishing with a 5-3 record and an eye-popping 0.74 ERA to go along with 68 strikeouts over 60.2 innings. His ERA total led all of Division II and still stands as an ECC single-season record. For the second straight year, he also led Division II in hits allowed per nine innings (4.6). In addition, Duran added no-hitters number two and three of his career with no-no's against Mercy and Bridgeport during the 2010 campaign.

Duran earned another All-Conference First Team selection in his senior season to wrap up his career with a 23-12 record to go with 301 strikeouts and a 2.32 ERA over 290.2 innings. His win, strikeout, and innings pitched totals all rank in the top-10 in ECC history.
