Gateway starting pitcher Tyler Thompson pitched seven scoreless innings and the Grizzlies held on for a 4-1 win Friday night against the River City Rascals at GCS Ballpark in Sauget.
A crowd of 7,052, which was the Grizzlies' second largest of 2014 and the 10th largest in franchise history, watched Thompson (3-0) dazzle for seven innings in his second pro start.
The right-hander from Cuba, Mo., allowed just four hits with no walks and six strikeouts to move his ERA to 0.92.
TJ Bennett gave the Grizzlies (31-14) a 1-0 lead on a second-inning RBI single and Kale Kiser tacked on a run in the fifth inning with a sacrifice fly to make the score 2-0.
With help from the Rascals (26-17) defense, Gateway added two insurance runs in the eighth inning on a Niko Vasquez triple and three River City errors.
River City added a run in the ninth before Richard Barrett finished off the Grizzlies 10th win in their last 12 games.
The Grizzlies finish their homestand Saturday night against the Rascals at GCS Ballpark.
