Hamer is one of the largest players on Alberta's high school circuit, checking in at 6-foot-6, 230-pounds. While his frame alone is enough to dream on, he backed it up with loud numbers. He took the crown of top exit velocity (103.8), and top fastball velocity (90.6). Fresh out of local ball, he's green across the board, but he's worth paying attention to as he develops this season.
