"We played better than we have been," Matewan Coach Danny "B.B." Perkins said. "But, we didn't finish them off and let them hang around. They got some runs late. Anytime anyone can hit the ball like Carter does, your team will stay in the game."
Gilbert's Josh Carter blasted two homeruns.
Ryan Altizer hit a triple and a single.
Travis Hatfield and Tommy Grimmett each hit a double, while Roger Ellis and Austin Trent hit a single apiece.
Grimmett was tagged with the loss on the mound.

The Tigers were playing without Max Whitt, who was out for unspecified reasons.
Copley, who suffered a sprained ankle during the Tigers' tournament play at Myrtle Beach, is still not 100 percent, Perkins said.
