The Austin Greyhounds made up a six-run deficit and then watched a one-run lead slip away as they lost to Forest Lake 8-7 in the Spamtown Challenge opener for both teams Friday in Marcusen Park.

The Brewers (7-4 overall) won the game in the bottom of the eighth when two consecutive runners reached base on errors with one out and Mike Schultz blasted a walk-off two-run double to deep center field.

“This was a tough loss,” Austin manager John Frein said. “It was a fun game and we came back. I thought we had it, but they deserved it. It’s kind of a bummer.”

Frein gave the Hounds (8-9 overall) their first lead of the night when he perfectly executed a safety squeeze by laying down a bunt to score a run in the top of the eighth. The Hounds ended up with the bases loaded with no outs after going up 8-7 but Tyler Leopold lined out and Nate Johnson and Matt Cano struck out to end the threat.

Cano tied the game up at 6-6 with a two-run double down the right field line with one out in the top of the seventh.

Austin had trailed 6-0, but it was able to force extra innings.

“We played okay and we showed promise and patience at the plate,” Frein said.

The Hounds will play Appleton at 4 p.m. and Cold Spring at 6 p.m. Saturday. To advance to Sunday’s final round, the Hounds will have to win both of those games and win a tie-breaker, which comes down to run differential.
