St. Thomas Baseball had a 3-2 walk-off, extra-inning win over Hamline at Koch Diamond in game one to start a doubleheader sweep of the Pipers. Ryan Lust singled home Jimmy Dolan with two outs in the bottom of the ninth inning.

Henry DeCaster allowed one earned run in eight innings and struck out five but got a no decision. Ben Meyer worked one inning and got the win in relief. After missing on prime scoring chances in the seventh and eighth innings, Dolan led off the ninth and was hit by pitch. He was bunted to second before scoring on Lust's single. UST got one hit from all nine players in the lineup.

In game two, UST scored six runs in the bottom of the sixth inning to break a 1-1 tie en route to a 7-1 victory. Ryan Zimmerman struck out 13 and allowed one run over six innings and now has won four consecutive starts. Shaun Falbo pitched a scoreless final inning.

DeCaster lowered his earned-run average to 1.76, while Zimmerman dropped his ERA to 2.45. The team's ERA in 10 MIAC games is just 1.91.

The Tommies (12-10 overall, 7-3 MIAC) kept pace with the leaders in the conference. St. Mary's (7-1), UST (7-3), St. John's (7-3) and Bethel (7-3) all swept Wednesday doubleheaders and are in a good battle at the halfway point of the 20-game conference schedule.

The Tommies are scheduled to play in Rochester on Friday against UW-La Crosse at 5 p.m. They will resume a suspended seven-inning game in the fifth inning with UST batting and leading 2-1. They also will play a nine-inning game with the Eagles.

St. Thomas is scheduled to play its final five MIAC doubleheaders in an eight-day span starting Sunday at Carleton.
