Answer:
The sentence is grammatically correct. It states that pitchers in the major leagues generally require four or five days of rest between games due to the physically demanding nature of pitching.
Step-by-step explanation:
Pitching in baseball involves throwing the ball at high velocity repeatedly, which puts a lot of strain on a pitcher's arm and shoulder. Pitchers also use a wide range of arm motions, such as throwing different types of pitches, which can further exacerbate this strain. In order to avoid injury and ensure that they are able to pitch effectively in the long term, pitchers generally require a few days of rest in between games. This allows their arm and shoulder to recover and reduces the risk of injury. Additionally, the rest period can also help the pitcher mentally prepare for their next game.
