Shagging (baseball)

In baseball, shagging is the act of catching fly balls in the outfield outside the context of an actual baseball game. This is most commonly done by pitchers during batting practice before a game, where they assist their hitting teammates by catching or picking up their batted baseballs and throwing them back to the pitching area in the infield. Batboys also help shagging baseballs, and it is reportedly considered a great honor among batboys to be asked to do this. This pre-game activity is widely disliked by pitchers, who argue that it does not benefit them at all, since it drains their energy and actually increases the risk of stiffness in the lower back and leg as a result of prolonged standing. In response to these claims, several teams have exempted pitchers from having to shag fly balls. In the Nippon Professional Baseball (NPB) league, teams pay groups specifically assembled to shag fly balls in place of pitchers, and the Los Angeles Angels of Anaheim recruit local firefighters in Arizona to do the job when the team plays in the Cactus League during spring training.

Although shagging baseballs is not considered to be dangerous, several freak injuries have occurred as a result of engaging in it. In 1943, just one season after collecting his 3,000 hit, Paul Waner accidentally gashed his foot while shagging a fly ball in a game against the Pittsburgh Pirates, his former team. This was probably due to Waner being nearsighted and his refusal to wear glasses; thus, he "played the outfield by ear." Nearly four decades later, Jerry Reuss was handed the honor of pitching on Opening Day in 1981, but suffered an injury to his calf while shagging baseballs for his teammates. He was replaced by unheralded rookie Fernando Valenzuela, who went on to win his next 8 consecutive decisions.
