"I'll keep doing it," Francona said with a laugh.
Francona is not sure what is behind Santana's improvement this season, but he has enjoyed watching Santana loosen up behind the scenes and excel on the field.
After home runs, Santana can often be spotted doing a dancing celebration with second baseman Jason Kipnis. Before a recent game, Santana donned boxing gloves in the clubhouse and playfully jabbed at Michael Brantley.
