On the 17th (Korea Standard Time), training assistants before the practice game between the national baseball team and NC at the Tucson Kino Sports Complex in Arizona unfolded a Major League official ball produced by Roland.

A certain maker’s mud was placed next to the unfolded official ball, and after a while, a training assistant was rubbing the ball with a little mud on the new ball.

Regarding the reason for purposely attaching mud to a new ball that is intact, a KBO official said, “Major League official balls often fall out of the pitcher’s hands due to their slippery surface, so certain brands of mud are applied before the game. “I’m working on mud to increase the friction of the ball,” he said.

In fact, official Major League Baseball rules stipulate that baseballs should be covered with mud. That’s why Major League Baseball’s ball looks yellow. 온라인카지노

Major League Baseball’s official ball produced by Roland will also be used at the WBC (World Baseball Classic), which will open in March today.

Meanwhile, in a practice match between the WBC national team and NC on the 17th, the players played their first game as WBC official balls.

Kim Kwang-hyun, Ko Young-pyo, Jung Chul-won, Won Tae-in, Jung Woo-young, Lee Eui-ri, and Ko Woo-seok took the mound one inning at a time and threw about 20 balls to improve their sense of practice.

The WBC national team will play its second practice game against the KIA Tigers on the 20th today.
