WINNIPEG, MAN. – The Winnipeg Goldeyes have signed left-handed relief pitcher Quinn Waterhouse.

A native of Bondurant, Iowa, Waterhouse has spent the past several seasons pitching in the Pioneer League, most recently with the Rocky Mountain Vibes.

Splitting time with the Vibes and the Boise Hawks in 2025, he compiled a 1-4 record over 38 appearances (three starts) with a 6.83 earned run average.

In total over his three professional seasons, he has tallied a 5-11 record in 113 games with a 6.57 ERA.

Waterhouse made his professional debut in 2023 with the Ogden Raptors after playing at Southern Illinois University Edwardsville (Edwardsville, Ill.) for three seasons (2020-22) and one (2023) at Lamar University (Beaumont, Texas).

“We are really excited to get Quinn on board,” said Goldeyes skipper Logan Watkins. “He’s a younger guy with electric stuff. Mid 90s from the left side is impressive, and he’s worked hard to develop the rest of his arsenal. I’m excited to see him pitch this summer.

Winnipeg now has seven players under contract for the 2026 season. American Association clubs may carry up to 33 players during spring training, which begins May 3.
