Dozier: 24 extra-base hits in August

Brian Dozier homersBrian Dozier‘s home run last night in Cleveland was his 24th extra-base hit since August 1. That is the highest total in a calendar month in Twins franchise history. He broke the mark set by Joe Cronin, who had 23 extra-base hits for the Washington Senators in July 1932 and again in June 1933. (The team relocated from Washington to Minnesota in 1961.)

The only other active player to produce at least 24 extra-base hits in a calendar month is Albert Pujols with 24 in June 2009.

Barry Bonds, Alex Rodriguez and Ken Griffey Jr. each rank in the top 10 all-time in extra-base hits but none of them ever had as many as 24 extra-base hits in a calendar month in their major-league careers.
