Josh Walker was picked by the Mets in the 37th round—a round that no longer exists by 17 rounds—in the 2017 draft. Most players taken in rounds that late don’t end up making it to the big leagues, but Walker made his debut with the major league team last year.
The results across his 10.0 innings with the Mets weren’t exactly ideal. Walker had a decent strikeout rate for a reliever, a bad walk rate, and a fairly significant home run issue. And he ended up with an 8.10 ERA at the end of the season.
