The curveball is a figment of your imagination

Whenever you hear someone’s curveball described as “dropping off the table” take it with a grain of salt.

According to one professor anyway, the curveball’s action is part-physics, part-illusion, the movement aided by a trick of the eye.

Criss Angel would be proud.

“There’s something physical about it and something illusory about
it,” said Bucknell University professor Arthur Shapiro. … “They look
like they jump or break or do all these funky things, but they don’t.
The idea that the bottom falls out isn’t so. I’m not saying curveballs
don’t curve. I emphasize that, yes, they curve. They just do so at a
more gradual rate. Instead of making a sudden hook, they would form a
really big circle.”

Shapiro explains that the eye exaggerates the break because peripheral
vision is processed differently than straight on vision by the brain.
So as the ball approaches and the viewpoint changes, the eye makes the
ball’s break look stronger than it is.

Shapiro made a very cool graphic to explain his idea, which he insists is only a hypothesis.

So what do players think? Hall of Famer Mike Schmidt offered his
opinion for the story, and he had a thoughtful take, saying he agreed
that the curveball presents an illusion to the hitter, but not due to
peripheral vision.

“Hitters are seeing the ball with both eyes, not out of the side of
front eye as suggested,” said Schmidt. “I believe the illusion is a
result of the speed with which the action takes place, not a peripheral
view. Then again, I’m not a scientist, just a hitter.”

Well, not just a hitter. Thanks to SPORTSbyBROOKS for this story.

Former Tigers infielder Casey McGehee has reportedly signed a one-year deal with the Yomiuri Giants of Nippon Professional Baseball, according to FOX Sports’ Ken Rosenthal.

It’s the fourth move the corner infielder has made in the last two seasons after seeing short-term stints with the Marlins, Giants and Tigers. He signed a minor league deal with the Tigers prior to the 2016 season, providing the club with some infield depth behind 24-year-old Nick Castellanos. When Castellanos hit the disabled list in August with a broken hand, McGehee was recalled from Triple-A Toledo for a 30-game stint and slashed .228/.260/.239 with one extra-base hit in 96 PA. His career batting line (.258/.317/.384 over eight seasons) isn’t too shabby, but his age and a long history of knee injuries puts a damper on his potential.

McGehee last appeared in the NPB circuit in 2013, when he signed a one-year, $1.5 million deal with the Tohoku Rakuten Golden Eagles. He spent the bulk of his season at the hot corner, batting an impressive .292/.396/.515 with 28 homers in 590 PA and appearing in the Eagles’ first and only championship run to date.

The deal comes with a club option for 2018, Rosenthal reports, though no figure has been specified.

Free agent left-hander Rich Hill is rumored to be entertaining a three-year, $40+ million offer from the Dodgers, reports Peter Gammons. The Boston Globe’s Nick Cafardo corroborated the report, adding that Hill could receive somewhere between $46 and $48 million from his former team.

Hill, 36, pitched to a 2.12 ERA and 3.91 FIP in back-to-back stints with the Athletics and Dodgers in 2016. While a chronic case of blisters on his pitching hand limited the frequency of his starts, he still figures to be one of the most productive and noteworthy starting pitchers on the market this winter.

The Orioles, Yankees, Red Sox, Rangers and Astros have all been mentioned as potential suitors for the left-hander’s services, though Orioles’ GM Dan Duquette said the club has yet to make a play for Hill and ESPN’s Jim Bowden pointed out that the Red Sox are less involved in trade talks than other interested parties.
