SCOTTSDALE, Ariz. (AP) — If the Arizona Diamondbacks want to win a lot of games this season they probably need right-hander Zac Gallen to throw a lot of quality innings.
If the franchise wants to be good for the next several years, it’s also imperative that the 25-year-old — who finished ninth in the NL Cy Young voting last season — stays healthy.
The challenge of balancing the present and the future is nothing new for Major League Baseball teams, who are particularly careful with star young pitchers. But the calculus might be even tougher in 2021 because pitchers are coming off a much smaller workload during the pandemic-shortened 2020 season.
Gallen, who finished with a 3-2 record and a 2.75 ERA last season in 72 innings, is adamant he’s ready to ramp back up to nearly 200 innings if needed, even if it appears unlikely the D-backs would push him that hard.
“I’m going to pitch until they tell me to stop pitching,” Gallen said. “And then I’ll probably still say, ‘No, let me go back out there.’”
There’s little doubt teams will be very careful extending their pitchers to the usual 180 to 200 innings that a typical starter logs in a 162-game season. There’s even talk about using six-man rotations for some teams, including the Seattle Mariners, who used the strategy for much of 2020 during the 60-game schedule.
“Our primary thought behind it is to preserve the health and well-being of our pitchers,” Seattle GM Jerry Dipoto said. “In an era where teams are trying to find a competitive advantage by throwing their starters for shorter lengths of time and just running them harder, we feel like our advantage, our competitive advantage is by keeping our pitchers healthy and having our best pitchers pitch over the length of the season, rather than the potential dangers of running them into the injury.”
But the strategy might not be a great decision for every team. The five-man rotation has been a durable staple for MLB teams over the past 70 to 80 years, even as sabermetrics have changed many of the game’s strategies.
The math is fairly simple. In a five-man rotation, pitchers make about 32 starts per season. Assuming an average of about six innings per start, that’s 192 innings through a 162-game schedule.
In a six-man rotation, the number of starts goes down to 27. At six innings a start, that’s 162 innings in a season, or 30 less than a pitcher in a five-man rotation.
Certainly, that means pitchers get more rest. But it also means a staff ace isn’t on the mound as much.
Colorado manager Bud Black is one who plans to stick with a five-man rotation if possible.
“A lot of times it’s what we can condition our players to do and right now our starting pitchers across baseball are conditioned to throw every fifth day,” Black said. “We can go on and on about pitch counts and 200 innings and all the things that go in with that, but we as an industry have created some of these standards — good or bad.”
