Former Kane County Cougars RHP Jon Duplantier is the recipient of MLB Pipeline’s Pitcher of the Year award this year, after he posted Minor League Baseball’s second-lowest earned-run average in the last 25 years.
Duplantier pitched for the Cougars in the first half of the season, going 6-1 with a 1.24 ERA, 78 strikeouts and 15 walks in 72.2 innings (13 games/12 starts). He was the starting pitcher for the Western Division team in the Midwest League All-Star Game. He also pitched for the U.S. team in the All-Star Futures Game.
The Arizona Diamondbacks prospect pitched in the hitter-friendly California League in the second half of the season, and still excelled. He went 6-2 with a 1.56 ERA, 87 strikeouts and 27 walks in 63.1 innings (12 starts) for the Visalia Rawhide.
Overall this season, he went 12-3 with a 1.39 ERA, 165 strikeouts and 42 walks in 136 innings (25 games/24 starts). Justin Verlander — you may have heard of him — was the only qualified MiLB starting pitcher to post a lower ERA in the past 25 years (1.29 ERA in 2005).
Duplantier also finished third in the minors with a .192 opponents’ batting average, and 12th with a 0.98 WHIP.
