SEATTLE — In 2006, back in the days when the Red Sox were trying to win, they outbid other determined teams to sign Japanese ace Daisuke Matsuzaka.
Matsuzaka was said to throw a mysterious pitch called the gyroball, which proved to be more fantasy than fact. But he did win Game 7 of the ALCS and Game 3 of the World Series in 2007.
Now, 17 years later, the Red Sox may actually have a pitcher who throws a gyroball.
After working on it during spring training, Garrett Whitlock will use a new pitch against the Seattle Mariners when he makes his first start of the season on Sunday.
“What’s it called? You’ll have to ask Bailey,” Whitlock said, directing a curious reporter to pitching coach Andrew Bailey.
Bailey referred to the pitch as a gyro slider or a bullet slider. It’s a slider thrown with a downward break.
