Before the season, it was reported that Mat Latos would probably be limited to around 150 innings. The idea is to limit a young pitcher’s workload and to gradually work the pitcher up to a 200+ innings/year level. Pushing a young pitcher who may not be prepared for the rigors of ~200 major league innings is a recipe for disaster.
Or so they say. This theory is largely based on the “Verducci Effect,” which says that pitchers under the age of 25 who experience an increase in workload of 30 or more innings see injury and/or a decrease in performance in the subsequent season. The Verducci Effect has been challenged and debunked, at least to some degree. There’s still a ton of work to be done in predicting injuries — we certainly don’t have any definitive answers, especially on any individual pitcher — thus we cannot just say that a dramatic increase in innings pitched for a young hurler will lead to injury and decreased performance. It might, it might not.
Anyhow, before the season, the San Diego Padres probably did not expect to be sitting atop the NL West in late June, with a 42-29 record. If the Padres play just .450 baseball from here on out, they will finish with 83 wins – in other words, at this point, a playoff run is very probable. Prior to the season, the Padres also probably did not expect Mat Latos to be the staff ace, carrying a 2.93 ERA in 86 innings (8.3 K/9, 2.3 BB/9, .94 HR/9).
With these new factors – the Padres playoff chances and Latos’ performance – added to the mix, it complicates the decision-making process regarding Latos’ workload. Sure, it’s a nice problem to have, but it’s also one that is extremely hard to make. Flags fly forever, as they say, and Latos is an important part of the Padres success. If he keeps pitching at this rate, I predict he’ll make about 31 starts, good for 190 innings. If the Padres cut him off at 150 innings, he’ll probably miss six or seven starts – or late August and all of September. Critical starts when the Padres will need him most.*
There’s the other side of the coin, too. Is it worth risking Latos’ future in an attempt to reach the playoffs right now? Latos is under control and cheap, and he has a chance to provide a lot of surplus value over the next few years, perhaps developing into a Jake Peavy-like ace, if things break right. Throwing him 190 innings in his first full season, many of them likely critical, high leverage innings down the stretch run, not to mention potential playoff innings, could do a lot to damage Latos’ future impact with the organization.
The good news is that the Padres don’t have to make a decision anytime soon, and they indicate as much in an article by Bill Center at the Union-Tribune. By the time we get to late August, maybe things will take care of themselves, and the decision will be made easier. Or, perhaps the Padres will be in the thick of a playoff race and Latos will still be performing well, making the decision that much tougher. We’ll have to wait and see.
*If there really is a set number, like 150, it might make sense for the Padres to rest Latos now and bring him back for the stretch-run. This would certainly be an out-on-a-limb strategy, with potential negative side-effects, but it might make sense, saving Latos – and having him well rested – for the late-season playoff chase.
