In the end, Omaha couldn't overcome its own miscues in its first conference loss of the season.

A misplayed line drive in the second inning, an uncharacteristic balk in the sixth and a baserunning blunder in the eighth all played a role in an 8-6 loss to newcomer St. Thomas at Tal Anderson Field.

The Tommies (4-13, 1-1) scored twice in the ninth to win Saturday after the Mavericks (8-13, 1-1) had rallied from a four-run deficit to take a short-lived lead. St. Thomas plated the go-ahead run on an infield single and then added another on a bases-loaded ground out to capture its first Summit League victory.

Omaha had three men on with one out in a tie game in the eighth, then ran itself out of a chance to move in front when it had two runners tagged out in a rundown following a pitch that briefly got away.

The Mavericks had wiped out a 5-1 deficit by scoring five times in the seventh, highlighted by Devin Hurdle's two-run single. The Tommies then pulled even in the eighth with a two-out RBI infield single.

St. Thomas scored a run on a base hit that never left the infield in each of the last three innings. It scored eight runs in the game without ever recording an extra-base hit. It had four infield singles.

After scoring a run in the first, the Tommies plated two in the second off Omaha starter Charlie Bell after a fielding error scored one and led another. Bell was replaced by Joey Machado after only two innings.

Machado retired the first 10 men he faced, then balked after a walk in the sixth. Max Moris singled in that runner to stake the Tommies to a 4-1 lead. The Mavericks later rallied off reliver Devon Schewe.

Harrison Kreiling (1-2) suffered the loss for Omaha by allowing the two ninth-inning runs.
