Jesse Hartong set the WPK single season winning percentage record when he went 20-2 while pitching for the San Antonio Keys just two seasons ago, but the 38-year old saw a quick erosion of his skills following that historic season, and having pitched exclusively in AAA this season he has announced that he has decided it is best that he steps away from the game at the conclusion of this season. Although Hartong is a borderline Hall of Fame candidate (HOF Monitor score of 86, JAWS of 58.6, HOF Standards of 44), he does leave the game as the career leader in wins with 230.
A few other significant players who announced their retirements recently are former Brewer team captain and starting pitcher Matt Helm, talented left-handed starting pitcher Jalen Cotton, who 3 times in his career led the league in losses, having the misfortune of nearly always pitching for very bad teams (he deserved better), and 4-time All-Star outfielder Eric Taylor, a talented player who never quite lived up to his potential.
