Gretz came to Sioux Falls in 2017, following a productive 2016 season with the St. Paul Saints. The Ohio State University graduate hit .244/.346/.353 in 65 games for the Canaries last year, hitting 3 home runs and 11 doubles with 22 RBIs. Canaries manager Mike Meyer has praised Gretz for his ability to grind out at-bats, and to balance skill with the bat with defense behind the plate.
