The Best Fit for Any Version of Carlos Rodón

As one of the few remaining free-agent pitchers, there will be a time (hopefully) soon enough when Carlos Rodón is a hot commodity. A pitcher coming off a 4.9 WAR season usually doesn’t have serious contract questions attached to them, but that’s the case for Rodón, who amassed that WAR total in only 132.2 innings and was given significant rest between starts, as his velocity dipped significantly over the course of the year. The end result is that he didn’t receive a qualifying offer from the White Sox and remained unsigned as the lockout began.
Rodón’s injury history combined with the in-season fatigue is alarming on its own, but a pitcher who can put together a 5-win season in under 200 innings deserves a fair assessment. How likely is it that those fatigue issues occur again, and if they do, what team is best suited to handle a mixed starter/reliever workload?
We’ll start with assessing the fatigue issues. As noted, Rodón threw 132.2 innings in 2021 — rather remarkable, considering he had only thrown 42.1 innings in ’19 and ’20 combined. Innings jumps that large are understandably scary, but every pitcher experienced that after the 2020 season; Rodon’s was the 24th largest year-to-year increase from that season to last year. That is something, but there was a significant lack of workload for Rodón in 2019 as well. Where does he rank in terms of innings jumps from 2019 and ’20 combined to 2021?
Name | 2021 IP | 2019-20 IP | Increase |
---|---|---|---|
Shohei Ohtani | 130.1 | 1.2 | 128.9 |
Alek Manoah | 129.2 | 17.0 | 112.2 |
Lance McCullers Jr. | 166.1 | 55.0 | 111.1 |
Jameson Taillon | 147.1 | 37.1 | 110.0 |
Triston McKenzie | 141.1 | 33.1 | 108.0 |
Jordan Montgomery | 157.1 | 51.2 | 105.9 |
Taijuan Walker | 159.0 | 54.1 | 104.9 |
Peter Solomon | 111.2 | 7.2 | 104.0 |
Carlos Rodón | 132.2 | 41.4 | 90.8 |
Chris Flexen | 179.2 | 91.4 | 87.8 |
Tyler Anderson | 167.0 | 79.4 | 87.6 |
Many of the pitchers here have suffered significant injuries before and once again ran into injury troubles this past season. Regardless, the jump for Rodón was not unprecedented; what’s maybe more concerning is the velocity drop in-season.
Rodón’s velo saw a more characteristic switch after his last start of seven-plus innings on July 18. Before then, there was a clearer build-up from innings 1–3 to innings 4–6; after, the relationship breaks. That start on the 18th was seemingly max effort the whole time, with the highest early-inning velocity he’d shown all year. There’s nothing that we can reasonably assume about the nature of his shoulder fatigue, whether it’s this one start that caused trouble or having hit a wall in general, but his season decline began there. He had built up to 89.2 innings before that July 18 start; everything after has the caveat of him either throwing through noticeable injury, receiving extended periods of rest, or spending time on the IL.
If we take those 89.2 innings as a benchmark of the healthy Rodón, we can look at other year-to-year workload increases to get a sense of what may be reasonable.
For those that do throw somewhere in the range of 90 innings, jumps in the range of 30–40 innings are within reason, although many of those who fall into that 80–90 range are midseason call-ups. In the 130-inning range, best-case jumps top out at 20 or so innings. Barring injury and without much else information to bake in, we would expect Rodón in 2022 to fall somewhere between 110 and 150 innings.
