It’s no secret that we’re in the midst of a lean period for starting pitchers getting elected to the Hall of Fame on the BBWAA ballot. Since the elections of 300-game winners Tom Glavine, Greg Maddux, and Randy Johnson in 2014 and ’15, just four starters have gained entry via the writers, two of them alongside the Big Unit in the latter year (Pedro Martinez and John Smoltz) and two more in ’19 (Roy Halladay and Mike Mussina). From a demographic standpoint, Halladay is the only starter born after 1971.
It’s quite possible the writers won’t elect another starter born in that shag-carpeted decade unless voters come around on Andy Pettitte (b. 1972) or Mark Buehrle (b. 1979), a pair of southpaws who cleared the 200-win mark during their exceptional careers, producing some big moments and playing significant roles on championship-winning teams. Yet neither of them ever won a Cy Young award, created much black ink, or dominated in the ways that we expect Hall-caliber hurlers to do. Neither makes much of a dent when it comes to JAWS, where they respectively rank 93rd and 91st via the traditional version, about 14 points below the standard, or tied for 80th and 78th in the workload-adjusted version (S-JAWS). Neither has gotten far in their time on the ballot, and both lost ground during the last cycle. Pettitte maxed out at 17% in 2023, his fifth year of eligibility, but slipped to 13.5% in his sixth, while Buehrle, who peaked at 11% in his ’21 debut, fell from 10.8% to 8.3%. Nobody with shares that low at either juncture has been elected by the writers, with Larry Walker (10.2% in year four, 15.5% in year six) accounting for the biggest comeback in both cases but still needing the full 10 years, capped by a 22-point jump in his final one.
