There was a time years ago when baseball players did not feel the need to be in great physical shape so baseball workouts were not common. Those days are long past, and the bigger, stronger, and faster motto applies to baseball as well as other sports. Many players cringe with the thought of physical training because, well, it's physical, and involves work and sweat.
Some conditions are beyond player's control, such as hitting balls solidly but failing to get base hits. Players have a good excuse for a low batting average when that happens, as they did what they could do to have hitting success. Over time though, the law of averages usually catches up and a player's average ends up where it should be. Other times though, players, make baseball hitting excuses when they really should not get in the habit of, as the following instances attest.
