Japanese baseball officials admit to altering the baseball to increase offense

Home runs and batting average have increased sharply in the NPB this season, and after months of denying that the ball had been altered in any way, Japanese baseball officials are admitting that they tinkered with it in order to “make the game more exciting” and increase offense:

Players and fans had repeatedly quizzed Nippon Professional Baseball (NPB) bosses after seeing a 40 percent rise in the number of balls that were slugged out of the park so far this season.

In April NPB said the specifications of their ball — each of which bears the signature of its commissioner Ryozo Kato — “have not been changed”, a statement that was repeated several times since.

But on Tuesday NPB came clean, saying they had asked manufacturer Mizuno to “adjust” the ball to give it greater bounce off the bat and demanded the company keep quiet about the switch.

Altering baseballs is not unprecedented in baseball history, of course. In 1930 offense made the so-called Steroid Era look like 1982 or something. Half the teams scored 900 runs or more and the average hitter in the American League — just the AVERAGE ones — hit .303/.360/.448. That winter baseball deadened the balls a bit, with the AL altering the stitching and the NL doing both that and adding a cover to its balls. Offense went down significantly in 1931, more so for the NL.

1987 is widely suspected to be another year in which the ball was altered. Baseball has never admitted to doing anything, but the season was an offensive aberration and unlike other eras of changing offense it was an outlier, with the next and previous years looking pretty similar and no other explanation that makes a lick of sense.

I strongly suspect that the baseballs were altered again in the 1990s. There were multiple explanations for increased offense at that time, including double expansion, much smaller parks, smaller strike zones, different hitting approaches and, of course, performance enhancing drugs, but I’ve always thought that the baseball had something to do with it too. Not that anyone ever wants to blame anything other than steroids.

But I think this NPB story shows that it doesn’t take much for offense to increase significantly. Sometimes just a change in the ball. Which league officials are inclined to deny.

Mets trade Curtis Granderson to the Dodgers

The Mets traded centerfielder Curtis Granderson to the Dodgers for cash considerations or a player to be named later, the teams announced late Friday night. Granderson was rumored to be drawing interest from teams earlier in the week, and found a landing place after slashing .256/.360/.721 since the start of the month. In a corresponding move, the Dodgers designated right-hander Dylan Floro for assignment to clear roster space for the outfielder.

As a whole, the 36-year-old’s 2017 campaign has been a tad underwhelming. Granderson entered Saturday batting .228/.334/.481 with 19 home runs and an .815 OPS through 395 PA, and accrued 1.7 fWAR to the 5.1 fWAR he produced during his pennant-winning, MVP-contending season in 2015. Still, with under $4 million remaining on his contract, another 20+ homer season around the corner and the defensive chops to man center field, it looks like a prudent deal for the Dodgers as they continue to bulldoze their way to the playoffs this fall.

The club has yet to outline their plans for Granderson, but his addition to a crowded outfield could displace centerfielder Joc Pederson, who turned in a meager .214/.329/.415 batting line through 292 PA in 2017. It could also have ramifications for fellow veteran Andre Ethier, assuming he’s healthy enough to compete for a starting role when he comes off the 60-day disabled list in September. The Mets, meanwhile, are expected to lean more heavily on rookie outfielder Brandon Nimmo, who’s made just five starts this season after struggling to get consistent playing time on the field.

Corey Kluber exits game with right ankle sprain

Indians’ right-hander Corey Kluber was removed from the sixth inning of his start on Friday night, bringing a streak of 14 starts with 8+ strikeouts to an unfortunate end after he sprained his right ankle. Kluber stumbled off the mound while trying to field a base hit from Eric Hosmer and was seen visibly limping as he moved to cover first base. He was allowed to stay in the game for one more batter, but quickly yielded a three-pitch single to Melky Cabrera and left the mound with head athletic trainer James Quinlan.

It was a poor ending to another strong outing by the right-hander, who delivered 5 1/3 innings of one-run, four-strikeout ball and took his 12th win of the season after the Indians amassed a nine-run lead. Postgame comments by Cleveland skipper Terry Francona suggest that Kluber isn’t facing a serious setback after sustaining the sprain, however, and might even be good to go by the time his next start comes around on Wednesday.

While the Royals escaped Friday’s loss without injury, the 10-1 drubbing pushed them 6.5 games back of the division lead and half a game behind the Twins and Angels for the second AL wild card berth. They’ll host a rematch on Saturday at 7:15 ET, with left-hander Jason Vargas set to face off against Indians’ righty Trevor Bauer.
