ÎçÒ¹¾ç³¡ baseball held walk-on tryouts for student players last week.

Nearly 120 years later, players couldn’t seem to help themselves, and MLB smashed all previous records. More homers might mean more exciting games, but some people question why the spike happened. A ÎçÒ¹¾ç³¡ chemist thinks he has some clues about this unusual surge in home runs.
