Winning pitcher Skye Robinette, in 5-1/3 innings, struck out 12 and allowed only two hits and an unearned run.
Chapman (5-1, 2-0 Region 3-3A) was already ahead, 5-1, when a rules error cost Clinton (3-4, 0-1) an out and led to further unraveling. It began in the fifth inning when Red Devil right fielder Griffin Fuller suffered an injury on the basepaths. Head coach Tom Fortman put designated hitter Konnor Richardson in the field, replacing Fuller. Later Fortman said he asked the plate umpire if he could keep Layne Cunningham in the game at catcher.
WIth a man on and one out in the bottom of the sixth, Cunningham singled, at which point Chapman head coach Steven Fusaro walked out and pointed out that Cunningham had batted out of order because Richardson originally batted in his place at DH.
Fortman, who freely admitted later that he knew the rule and was preoccupied with concern for his injured player, was ejected because he said the umpire had approved the illegal substitution.
"I made a mistake, bottom line," Fortman said. "We didn't play well, and that's on me as a coach. It's my job to get these boys up, ready to play, and I didn't do it tonight.
Chapman then scored four more runs in the top of the seventh inning.
First baseman Landon Beiler doubled in two runs in the first inning and another in the fifth, and Pearson Timmons also doubled twice for the Panthers.
Taylor Bailey scored Clinton's only run after leading off the fourth inning with a double. He stole third and scored on an error by pitcher Robinette. The only other official Clinton hit was by Chance Ewell in the fifth because Cunningham's hit was disallowed.
