Pitcher Aaron Marsden pitched six years as a pro, never moving past A ball.
Marsden was 8-0 with a 1.45 ERA as a high school senior and was named North Dakota's Player of the Year by USA Today. He was 6-3 with a 5.90 ERA in junior college in 2001, then was taken by the Cleveland Indians in the 34th round of the 2001 amateur draft (but did not sign). Transferring to Nebraska, he improved to 8-1, 2.70. He made All-Big 12 Conference and was second in the Big 12 in average allowed, third in ERA and 5th in wins. The big lefty had a 8-3, 2.90 record for Nebraska in 2003, fanning 113 and allowing only 21 walks in 115 innings. He was again one of the Big 12's best, finishing second in the Conference in ERA and beating out the likes of Scott Baker, Huston Street and J.P. Howell as the Conference Pitcher of the Year.
He was selected by the Colorado Rockies in the third round of the 2003 amateur draft, the 77th overall pick (between John Hudgins and Ryan Garko) and made his pro debut that summer with the Tri-City Dust Devils. With Tri-City, he was 4-3 with a 2.79 ERA. He was 8th in the Northwest League in ERA, between Jared Wells and Brian Lynch. Baseball America named him the loop's #11 prospect, between Ching-Lung Lo and Jamie D'Antona. In 2004, he had a 11-8, 4.58 record for the Salem Avalanche, finishing among the Carolina League leaders in wins (tied for second with Josh Shortslef, Wardell Starling and Marc Kaiser, two behind Jarrett Gardner), innings (165, 2nd to Kaiser) and homers allowed (30, 1st, 7 more than runner-up Alberto Arias). With the Modesto Nuts in 2005, he tied Mike Prochaska for the California League lead with 12 losses (6-12, 6.62) and allowed a .330 average.
He later went on to pitch three seasons in the independent leagues, primarily the American Association. In 2006, he toiled for the Lincoln Saltdogs (20 H, 11 R in 11 2/3 IP) and Sioux City Explorers (3-7, 7.01, 102 H in 69 1/3 IP). In 2007, he was with Sioux City (0-2, 17 H, 16 R in 7 2/3 IP) and the Fort Worth Cats (6-4, 3 Sv, 3.83). He ended up in 2008 with the Sussex Skyhawks (5 H, 3 R in 2 IP) and El Paso Diablos (1-0, 2 Sv, 2.25).
For his career, he was 31-36 with 6 saves and a 5.28 ERA in 141 games as a pro (79 starts), with 340 strikeouts, 187 walks and 634 hits (67 homers) in 521 2/3 innings.
