ARLINGTON — Matthew Dickeys two-run double capped a decisive four-run fifth inning for Mansfield Legacy, which remained unscathed in District 15-4A after a 5-2 victory over host Mansfield Summit on Friday night.Corey Murray and Sam Muhofski also had RBIs in support of pitcher Branden Bohuslav, who labored at times but tossed a complete-game six-hitter.Gutsy, coach David Walden said of his senior pitcher. Lot of guts out there tonight. He didnt have his best stuff, and they are a really good hitting team.He just kept battling and battling.The Broncos improved to 13-0 in district and 18-9 overall. Summit, paced by run-scoring hits by Manny Chavez and Corey Pickens, fell to 10-3 and 19-10.Bohuslav battled out of jams in each of the first two innings.The Jaguars put two on with one out in the first and runners on second and third with two outs in the second, but failed to score in each instance.Brady Usherwood hit a long fly ball to the farthest reaches in left, but outfielder Karson Houston had room to move under it for the third out.Legacy broke open a 1-1 game in the fifth.Houston and Kale Ward each scored on walks with the bases loaded and two more on Dickeys drive to left-center field.The Jaguars answered with a single run in the fifth, but their one-out threat ended in a 6-4-3 double play.Bohuslav, who struck out nine Jaguars, seemed to get stronger at that point, even with more than 100 pitches thrown. He finished with 122.He retired the final six for his seventh victory against one loss on the season.Walden said the plan was to relieve Bohuslav for the bottom of the seventh.I asked them if I could go back out; I wanted this game, said Bohuslav, who walked two hitters. I was a little nervous at the beginning, wanting to do too much to the ball.I didnt have my best stuff, but I worked in the bullpen to find it. I just kept trying to throw strikes.Legacy loaded the bases in the third with two outs and cleanup hitter Murray at the plate. The first pitch slipped past to the backstop, a wild pitch that scored Chayce Steelman with the first run of the game.Pickens, who took his first loss of the season for Summit, got out of the inning without any further damage by inducing a fly ball from Murray.The Jaguars, who are now tied with Waxahachie for second in district, tied the game on Chavezs run-scoring single that found center field and scored Alex Lang.The Broncos have a nondistrict game Saturday against Prosper. On Friday, they face Lancaster, with a perfect district campaign on the line.It would be awesome for these kids, Walden said about the possibilities. They have really worked hard.
