MIT physicist Aaron Leanhardt has been credited with creating the torpedo bats. Leanhardt previously served as a hitting analyst with the Yankees before he joined the Miami Marlins as a field coordinator in the offseason.

The New York Yankees have gotten off to a record-setting start to the campaign.  To begin the year, the Yankees were able to sweep the Milwaukee Brewers.

At that point, the Yankees were already four home runs into a historic nine-homer barrage that resulted in a 20-9 blowout. They concluded the three-game sweep with 15 homers to tie the MLB record for the most long balls through a team's first three games.
