Preston Walker's two-run single in the third inning made it 4-0.
Hancock (12-4) will play Sidney for the MAC championship at 4:30 p.m. Thursday at Afton. Sidney beat Oxford, 6-3, in the other semifinal. The Warriors beat Hancock, 9-5, last week.
Downsville 5, Windham 3
Brad Dreher struck out 12 in a five-hitter and went 2-for-3 with an RBI as host Downsville clinched the Mountain Division title with a Delaware League victory over Upper Division winner Windham.
The same teams will play in the crossover final Thursday at Neahwa Park.
"He's one of the better pitchers in the league," Downsville coach Tom Rose said of Dreher, who also walked five. "He throws hard, he throws strikes, he has a good curveball and he's able to spot his pitches. He got ahead in the count and had a lot of swing and misses."
The Eagles (8-3) scored twice in the first inning and three more in the second inning off a losing pitcher Anthony Pettignano. Dreher had an RBI single and Austin Lamica contributed an RBI groundout in the first inning.
In the second inning, Dylan Murphy led off with a double and Nick was hit by a pitch. Justin Baxter then bunted and reached on an error that scored Murphy. Matt Rampe followed with a sacrifice fly and Baxter scored on a wild pitch to make it 5-0.
"It's a good feeling," Rose said of winning the division. "We won it last year and lost to Stamford in the final. We lost our first two games of the season to Margaretville and Davenport, and we had to win out to get in this situation. We've played well since losing to Davenport. It kind of lit of fire under them and they rose to the occasion."
Windham's Anthony Savasta hit an RBI single in the seventh inning to make it 5-3, but Dreher struck out the final batter.
