Mariners right-hander Hisashi Iwakuma was expected to begin a minor-league rehab assignment this week as he comes back from a spring training finger injury, but instead the team had him throw a 58-pitch simulated game yesterday.
Iwakuma told reporters afterward that he felt very good during Tuesday’s simulated game, saying “the ball jumped out of my hand pretty well” and “I feel pretty close now to the regular season.”
Greg Johns of MLB.com reports that Iwakuma will likely make a rehab start Sunday at Triple-A, at which point he could be cleared to come off the disabled list and rejoin the rotation next week.
Seattle is waiting for Iwakuma, Taijuan Walker, and James Paxton to get healthy and join Felix Hernandez in what has the potential to be an excellent, high-upside rotation.
“Work fast and throw strikes” has long been the top conventional wisdom for those preaching pitching success. The “work fast” part of that has increasingly gone by the wayside, however, as pitchers take more and more time to throw pitches in an effort to max out their effort and, thus, their velocity with each pitch.
Now, as Ben Lindbergh of The Ringer reports, the “throw strikes” part of it is going out of style too:
Pitchers are throwing fewer pitches inside the strike zone than ever previously recorded . . . A decade ago, more than half of all pitches ended up in the strike zone. Today, that rate has fallen below 47 percent.
There are a couple of reasons for this. Most notable among them, Lindbergh says, being pitchers’ increasing reliance on curves, sliders and splitters as primary pitches, with said pitches not being in the zone by design. Lindbergh doesn’t mention it, but I’d guess that an increased emphasis on catchers’ framing plays a role too, with teams increasingly selecting for catchers who can turn balls that are actually out of the zone into strikes. If you have one of those beasts, why bother throwing something directly over the plate?
There is an unintended downside to all of this: a lack of action. As Lindbergh notes — and as you’ve not doubt noticed while watching games — there are more walks and strikeouts, there is more weak contact from guys chasing bad pitches and, as a result, games and at bats are going longer.
As always, such insights are interesting. As is so often the case these days, however, such insights serve as an unpleasant reminder of why the on-field product is so unsatisfying in so many ways in recent years.
