Jake Vieth slammed a walkoff home run in the bottom of the 12th inning Wednesday to lift the Anchorage Bucs to a 6-4 victory over the Anchorage Glacier Pilots.
The game was the first of a best-of-3 Alaska Baseball League semifinal series between the Bucs and Pilots at Mulcahy Stadium.
In the other semifinal series, the Mat-Su Miners stopped the Peninsula Oilers 3-1 at Hermon Brothers Field in Palmer.
Doubleheaders are scheduled at both parks Thursday, although a second game will only be necessary if a Wednesday loser is victorious in the first game.
Vieth's game-winner came after Todd Lott drew a leadoff walk. It was his second two-run homer of the night — Vieth also blasted a bomb in the third inning to put the Bucs up 3-1.
The Pilots scored three runs in the fourth to grab a 4-3 lead. Cameron Thompson and Sam Cohen both stroked RBI triples and Chandler Anderson hit an RBI double that inning.
The Bucs tied the game 4-4 when Lott scored on a passed ball.
Both teams squandered a significant number of base runners — 12 for the Pilots, nine for the Bucs.
In Palmer, the Miners got seven strong innings from pitcher Spencer Henson, who scattered three hits, walked four and struck out four.
Quin Cotton led Mat-Su's six-hit attack with a pair of singles, including one that drove in a run in the Miners' two-run seventh inning.
The winners of the two semifinal series will meet in the Top of the World Series, which begins Friday. The host of the series will be the semifinal winner with the highest seed — the Miners are the top seed, followed by the Bucs, the Pilots and the Oilers.
