COLLEYVILLE — Keller is off to the start it wanted in beating Flower Mound Marcus 3-0 on Thursday at Colleyville Heritage.The Indians lead the Class 4A Region I semifinal softball series 1-0 with Game 2 set for 7:15 p.m. Friday at Colleyville.Keller (30-4-1) used a couple of Marcus errors to generate runs and received a pitching gem from freshman Kaylee Rogers.“I struggled in the last series with my pitches not moving,” she said. “Tonight, though, things were working and I felt comfortable out there.”Rogers pitched seven shutout innings and scattered five hits. She struck out out only two and let her defense do the work. Marcus (29-7-1) stranded six runners.Keller’s offense, though, squeezed out just enough runs by taking advantage of timely mistakes and building some cushion for Rogers.Marcus pitcher Hannah Null had worked out of a jam in the fourth inning with a strikeout, but a passed ball allowed Grace Srichantra to score from third, extending the inning.Shelby Henderson, who was also aboard, advanced to second on the passed ball, then scored on Tori Charter’s dribbler to second base.Keller also plated a run in the first, which Rogers said can also work against a pitcher in a pressure situation.“Sometimes you feel like you have to keep that lead but when we got a couple of more, that made it less nerve-wracking,” she said. “When need to keep this same intensity and try to get them rattled and hopefully we can come out with one more win.”Null pitched seven innings, as well, giving up three runs, only one earned and four hits.She struck out 12, which was a similar performance to a Game 1 loss to Mansfield Timberview in the area round.Keller managed to get only three balls out of the infield off Null.“That’s what we’re trying to do is put the bat on the ball and see what happens,” Keller coach Lindsey Strong said. “You have to do that against a pitcher like that.”Strong was non-committal on Rogers starting Game 2, but she did start all games in the regional quarterfinals.
