MIDLOTHIAN — Cole Hearrean wore a big grin and a bag of ice on his left arm Thursday night after leading Mansfield Legacy to an 8-3 victory over Red Oak in Game 1 of a Class 4A Region II quarterfinal best-of-three baseball series at Midlothian High School.The senior left-hander piled up 12 strikeouts on the mound then pounded out two doubles and a three-run homer.“I got stronger as the game went longer,” Hearrean said. “When I hit good, I usually pitch well. I felt really good on the mound after I hit the two doubles.”Game 2 is at 7 p.m. Friday at Midlothian. If a third game is necessary, it will be at 1 p.m. Saturday. Hearrean’s effort wasn’t bad for a pitcher who thought he was about to get yanked from the game in the second inning.The Broncos (26-9) had beaten Red Oak (22-14) twice on their way to claiming the District 15-4A championship, but found themselves down 3-0 early.“We started a little shaky at first,” said Legacy coach David Walden. “Cole really settled down and pitched like he has all year.”Hearrean was 7-1 with a 1.47 ERA and 76 strikeouts this season.Walden said the key to his team’s success was going deep in the count against Red Oak starter Peyton Brock and reliever Tyler Welch.Perhaps no at-bat showed this better than Hearrean’s turn at the plate in the bottom of the sixth. With the game still close as Legacy led 5-3, the Broncos had two runners on base. Facing a full count, Hearrean fouled off four consecutive pitches. He then deposited one over the left-field fence to put the game away.“That was just a bomb,” Walden said.
