Nick Loftin made it to the pro level this year by getting on base. He was leading all of the majors and minors for a while and sported a 21.2% walk rate in Omaha this year. The offense at the pro level has struggled mightily, so they brought him up, and to be fair, he has been reasonably productive, but the walks disappeared. Through 15 games at the major league level, he has three walks for a 6.1% walk rate.
Vinnie Pasquantino made his way through the minors by being extremely selective, walking and doing damage with pitches in the zone.
