I gambled sending the kid home from third, but I just usually do. I want to make a teenager make a perfect throw.Hill scored two batters later on an RBI single by Drew Brown. Connor Combs drove in three more Carroll runs on a single to the right-field wall. Two more RBI singles by Chris Turner and Hayden Zier and another run on a bases-loaded walk capped the scoring.Carroll starter Tyler Alexander tossed seven scoreless innings with seven strikeouts. Alexander and the defense stepped up all night in pressure situations to get out of jams as the Rebels (14-6, 2-1) loaded the bases in three separate innings without scoring.Hes such a smart pitcher and he spots his pitches so well, Hughes said. Tyler really didnt have his normal stuff tonight, but some nights are like that.Ben Leeper came in for Carroll in the eighth, struck out two and picked up the save.Richland starter Austin Pryor pitched a gem through seven innings. The senior lasted 7 2/3 innings, struck out seven and gave up four earned runs.
