Emmitsburg, Md.- Host Mount St. Mary's (7-6) erupted for eight runs in the seventh inning and defeated UMBC, 12-6, in their home opener in chilly conditions at E.T. Straw Family Stadium.

UMBC junior pitcher Luke Johnson struck out a career-high 10 batters in 5.2 innings. He allowed three runs, all coming in on a Mount home run in the fourth inning.

The Retrievers (4-5) were blanked through four innings, but Christian Easley's single to left field plated Luke Trythrall and Michael Cilio to cut the deficit to 3-2.

UMBC would take the lead as four Retrievers touched the dish in the seventh. With one out, Trythall pulled a double down the line in right to score Cilio from first base. Anthony Swenda followed with a gapper to left-center to score Trythall and give UMBC a 4-3 lead. After a second out, Ian Diaz' single up the middle scored Swenda and Leewood Molessa drove home Diaz with a base hit to left field to give the visitors a 6-3 lead.

But in the bottom of the inning, the first eight Mountaineers to bat reached base and four of those runners came across to score.  The hosts tacked on three additional runs and added one in the bottom of the seventh to close the scoring.

Trythall led the offense with three hits, two runs scored and a run driven in. Swenda and center fielder Justin Taylor added two hits apiece and Cilio scored two runs.

The two teams will play a doubleheader in Emmitsburg on Sunday, with game one starting at noon.
