Among those 38, Teheran ranks third-worst in walks per nine innings; he’s 25th-best in strikeouts per nine. He’s 28th in WHIP (walks/hits per innings pitched). And yet: He’s 11th in opponents’ batting average. He has walked 62 men, second-most among NL pitchers, and has hit a league-high 11. Still, his left-on-base percentage is 12th-best in the league, and he has stopped giving up home runs. His HR-per-nine percentage is 10th-best.
Why has this been Teheran’s best year since 2016? At a time where everybody is hitting homers, he has stopped supplying them. He’d rather walk a guy, or several guys, than yield a homer. He doesn’t mind pitching with men aboard; heck, he has come to thrive on it. The downside is that’s not eating innings at the same rate. He has averaged 5-1/3 innings this season; in 2016, he averaged 6-1/3.
