Dubuque Hempstead put up 10 runs over six innings against Indianola and starting pitcher Andrew Redman threw six shutout innings as the Mustangs beat the Indians 10-0 in the first class 4A quarterfinal Wednesday afternoon at Principal Park.

The Mustangs got on the board early as they put up a run in the bottom of the first. Brad Duwe singled, stole second and scored on an RBI single from Redman.

The game remained 1-0 in favor of Dubuque until the bottom of the fourth when the Mustangs tallied another three runs.

With two outs in the fourth, Hempstead rattled off four straight singles and got help on an error from shortstop Alex Gross to plate three runs and chase Indianola starter Michael Chia from the mound. At the end of the fourth inning, the Mustangs held a 4-0 advantage.

Hempstead got back to work in the bottom of the sixth off of Indians’ reliever Mark Eubank. Eubank allowed three runs without recording an out as the first four batters reached on three singles and a walk.

After a sacrifice fly from Jon Reed to make the score 8-0, Eubank walked Toby Decker and was relieved by Brandon Abernathy. Abernathy walked the first batter he faced, Duwe, to load the bases. Redman then smacked a fly ball to center field which brought in Decker from third. Center fielder Marshall Mahr attempted a throw to third to cut down Duwe, trying to advance from second. The ball instead found the dugout and allowed Duwe to take home, giving Hempstead the victory.

Starter Chia (7-1) took the loss for Indianola, his first of the season. Chia gave up four runs (three earned) on six hits over three and two-thirds innings.
