The New York Times reports on Yu Darvish’s comments to the Japanese media last week about arm injuries and stuff. Upshot: he’s all for a six-man rotation:
. . . Darvish said he believed that a shift to a six-man rotation by major league teams could significantly reduce the stress on all those elbow ligaments by giving pitchers a critical extra day to rest and limiting their starts . . . Speaking to Japanese reporters in Minneapolis last week, he said, “If you really want to protect players, we should add one more spot to the starting rotation.”
He got some backup from teammate Colby Lewis who spent two years in Japan and was used to the once-a-week pitching schedule (Japanese teams play six days a week and have six-man rotations).
Eh. Could it reduce pitcher injuries? It’s possible. There is some, albeit no definitive evidence that elbow injuries are less frequent in Japan. But there are also tradeoffs in terms of (a) giving less effective pitchers more innings; and (b) requiring teams to devote yet another roster spot to a pitcher. This in an age when teams are already frequently playing games with only two position players on the bench plus a backup catcher they won’t use unless they’re forced to. Sure, ideally you’d think teams would get rid of a reliever for an extra starter, but when was the last time a manager gave up a reliever even when it made sense? Heck, they’d sooner play infielders in the outfield than get rid of that 13 or 14-man pitching staff/security blanket.
There would have to be major roster rules changes to accompany such a thing, as they have in Japan. There rosters are 28-men deep instead of 25 and a couple of players are activated/deactivated on a game-by-game basis. If you do that here maybe it helps, but it still doesn’t solve the problem of using a guy who, today, couldn’t crack your rotation as a once-a-week starter.
If the injury/start frequency evidence got more definitive, sure, you do what you do in order to save your resources. But until then it’s a pretty tall cost to go with a six-man rotation on the regs.
MLB.com’s Jenifer Langosch reports that Cardinals’ shortstop Aledmys Diaz has been sporting a new look around Busch Stadium with a pair of “strobe glasses,” technology-enhanced specs designed to help athletes focus on the ball. Like a strobe light, the lenses of these glasses affect a player’s vision by rapidly changing opacity, giving its wearers the illusion that the objects they see are moving more slowly than normal. Once a player adjusts to the new speed of play, they gain a greater sense of control and are able to time their actions with more precision.
Diaz isn’t the first MLB player to utilize the technology, just the first Cardinals’ player to do so. It’s been tested by Bryce Harper, Corey Brown, Tommy Joseph, Austin Hedges and Joe Mauer, among others around the league, and has been used for everything from refining a catcher’s reflexes behind the plate to tweaking a hitter’s ability to track a pitch. Per Langosch, Diaz has been using the glasses to hone in on the ball during pregame drills, increasing both his confidence and response time on the field and improving his defense at short.
The shortstop has been the focus of some concern this season after seeing a sizable dip in his production at the plate, and his five fielding errors, 0.6 UZR and 0.6 fWAR haven’t helped matters, either. He sustained a minor thumb injury during an at-bat on Friday night, and was left off of the Cardinals’ starting lineup on Saturday, though manager Mike Matheny didn’t rule out his ability to pinch-hit during the series. While the strobe glasses are a good start, Diaz will need more than a pair of specs to match the spotlight-worthy performance he turned out during his rookie season in 2016.
Red Sox’ left-hander Eduardo Rodriguez may finally get a chance at cracking the rotation again, assuming all goes well in Double-A Portland first. Rodriguez took the field prior to the club’s afternoon session with the Angels, firing 68 pitches in a simulated game as he prepared for an upcoming rehab assignment in Portland on Thursday.
The 24-year-old southpaw suffered a right knee subluxation during pregame warmups on June 1, and it’s been a slow path to recovery ever since. It’s not the first time Rodriguez has had issues with his right knee — he sustained a similar injury during spring training last year — and this time around, the Red Sox weren’t about to gamble with their starter’s health. Ian Browne of MLB.com reports that Rodriguez was put in a knee brace and underwent exercises designed to help him regain some mobility and stability while he worked back up to full strength on the mound.
He’ll still need to prove he can throw a 75- to 80-pitch outing in Double-A, and barring any significant setbacks, will likely rejoin the Red Sox’ pitching staff when they visit the Rangers next month. In the meantime, the club will continue to cycle starters through the No. 5 spot, which has seen no fewer than three different pitchers since Rodriguez hit the disabled list. The lefty is 4-2 in 10 starts this season after logging a 3.54 ERA, 3.1 BB/9 and career-high 9.6 SO/9 through his first 61 innings.
