After being tied 14-14 midway through the first half, Eastern Michigan went on a 12-2 run to take a 26-16 lead at the half.
Marshall shot a woeful 21.4% in the first half, while EMU used their 46.2% shooting to go on the run that pulled them away from Marshall for good.
Marshall's Catie Knable hauls in a rebound over EMU's Kris Kachaturoff.
"There's old adages in basketball that if you get more shots than your opponent, you should win," said Marshall first-year coach Royce Chadwick after the game. His squad put up 61 shots to Eastern Michigan's 50 during the game. "We've just pretty much dispelled everything there is in the basketball book during the course of these games."
Eastern Michigan enjoyed a double-digit lead the rest of the game, with the largest coming at the 9:43 mark with the score 42-24. The Herd did cut the EMU lead down to 11 with a minute to play, but Kris Lindsay's two free throws set the final 57-44 score in stone.
"This is crazy, but we've played two of our better games the last two games we played," Chadwick commented. "We're fighting around. We're just not able to knock down a good look. And the only way to fix it is to keep working at it."
Marshall place two players in double figures: Ida Dotson led all MU scorers with 13 points, while Andrea Fitzgerald added 11 points. EMU, meanwhile placed four players in double figures, led by Shani Charles' 16 points. The Eagles' Kris Kachaturoff hit a double-double with 12 points, 12 rebounds, the only player in the game to do so.
"Maybe we're not focused," said Marshall guard Ida Dotson. "Maybe a little bit of everything."
With the loss, Marshall falls to 6-16 overall, 2-9 in the MAC. The Eagles improve to 13-9 overall and 6-5 in the MAC. The Herd next plays at MAC East rival Buffalo this Wednesday night.
