SOUTH WILLIAMSPORT — Only in Little League could a team score four runs, pitch a no hitter, and barely escape with a victory.

But that's just what the team from Beaverton, Ore., did in a wild 4-3 win over Lemont, Ill., in the U.S. semifinals at the Little League World Series on Wednesday.

Derek Keller and Devon DeJardin combined for the no-hitter and DeJardin also knocked in the go-ahead run with a squeeze bunt in the top of the sixth for Beaverton, which advances to Saturday's U.S. title game against the winner of Thursday's Portsmouth, N.H.-Columbus, Ga., matchup.

The Mexican champions from Matamoros belted three home runs in an 11-0, mercy rule rout of Barquisimeto, Venezuela, in the earlier International semifinal. Mexico will play the winner of Thursday's game between Kawaguchi City, Japan, and Dhahran, Saudi Arabia, in the International championship game.

Keller went four innings, giving up a pair of runs in the third on a wild pitch and a sacrifice fly. DeJardin pitched a perfect fifth before loading the bases with two outs in the sixth on a pair of walks and a hit batter. Dane Kempke scored on a wild pitch before DeJardin got Michael Hall to ground out to end the game.

"I felt good before the game and I really thought I would pitch well," Derek Keller said.
