Nobody envisioned Shane McClanahan as a contender for the American League’s Cy Young Award.
McClanahan had a nice rookie season for the Tampa Bay Rays last year — 10-6, 3.43 ERA — but that’s all it was. Nice. He certainly didn’t establish himself as one of the league’s outstanding pitchers.
This year has been a different matter. McClanahan went 9-3 with an AL-leading 1.74 ERA in 2022’s first half, which ended on July 6. He was named to the league’s pitching staff for the All-Star Game.
Sandy Alcantara’s story varies a bit, though not by much. He debuted in 2017, so he’s been around longer than McClanahan, yet he was no more dominant for the Miami Marlins than his cross-state counterpart was for the Rays. Alcantara’s win-loss record through last season was 20-34.
His improvement this year has been dramatic, putting him in the mix for the NL’s Cy Young Award. Alcantara’s first-half record was virtually identical to McClanahan’s — 9-3, 1.82 ERA — and he, too, made the squad for the All-Star Game.
The two Florida pitchers are alike in another regard, too. They amassed the best base values in their respective leagues during the first 13 weeks of the 26-week season, a true measure of their overall effectiveness.
McClanahan posted a base value of minus-74, which means he surrendered 74 fewer bases than the typical big-league pitcher would have allowed under the same circumstances. That was the best first-half BV in either league, eight better than the American League runner-up, Justin Verlander of the Houston Astros, at minus-66.
Alcantara’s BV of minus-67 was the best in the National League through July 6. It was one base ahead of Max Fried of the Atlanta Braves at minus-66.
The first step in determining a pitcher’s BV is calculating his ratio of bases allowed per out, abbreviated as BPO. This is the process: (1) Count the number of bases a pitcher surrendered through hits, walks, hit batsmen, stolen bases, sacrifice hits, and sacrifice flies. (2) Count the number of outs the pitcher accumulated. (3) Divide the total of bases by the number of outs.
The typical big-league pitcher gave up .663 bases per out in the first half of 2022. McClanahan allowed 123 bases and secured 297 outs, giving him a microscopic BPO of .414, the best for any starting pitcher in the majors as of July 6.
BV is calculated by multiplying a given pitcher’s outs by the BPO for all pitchers. A typical pitcher in McClanahan’s circumstances would have surrendered 197 bases (297 outs multiplied by a .663 BPO). His actual total of 123 bases is 74 below the norm, so that’s his BV.
You’ve undoubtedly noticed the key difference between base values for hitters, which I posted last Tuesday, and today’s figures for pitchers. Batters strive for a strongly positive BV, while pitchers aim for the biggest negative number they can get.
Scroll down for several pitching breakdowns, starting with the 10 first-half leaders in base value in each league, followed by the pitchers with the worst BVs. The final two lists contain the best and worst BVs for each of the 30 clubs as of July 6.
