The Redhawks took control early. Colin Williamson led off the game with a triple and swiped home to go up 1-0. La Roche added four more runs over the first three innings including a 2-run double by Brian Tougher for a five run lead.
Thiel cut the lead to 5-3 in the fourth inning but Feikles' homer came in the fifth and Hadjuk gave up just one run over the final five frames.
Hadjuk struck out six to earn his fourth win of the year and his second complete game.
La Roche enters the hardest part of their schedule with three games against top 10 opponents. Baseball travels to #6 Heidelberg on Thursday before hosting a double-header against #2 Frostburg State on Saturday.
