I took a glance at some rosters in the Pioneer League. Carter Raffield was a 14th round pick back in 2021. He signed for $125,000 but never appeared in a minor league game, presumably due to injuries. He managed to pitch in a few games for the Glacier Range Riders. Things did not go well.
Also having pitched in the Pioneer League this season is Carson Lambert. The undrafted free agent from last year spent a little less than 3 weeks in the organization. This year he pitched for the Oakland Ballers and was 2nd on the team in innings pitched.
