Ryan Braun and Corey Hart each had doubles in last night’s 4-1 Brewers win over the Cubs. The Brewers have three of the top four leaders in the National League in extra-base hits with Aramis Ramirez (65), Braun (63) and Hart (59).

The trio of Braun, Hart and Ramirez are looking to become the first trio of Brewer players to each have 70 or more extra-base hits in a season. Five times in club history two players had 70 or more extra-base hits in a season, but never three teammates. Those five previous times:

1982: Cecil Cooper and Robin Yount

2001: Jeromy Burnitz and Richie Sexson

2008: Ryan Braun and Corey Hart

2009: Braun and Prince Fielder

2011: Braun and Fielder

With Hart’s next extra-base hit, the trio will become the eighth threesome (or more) in team history to have 60 or more extra-base hits in a season. In 2010, the Brewers had four players who ended the year with 60-plus extra-base hits: Braun, Hart, Rickie Weeks and Casey McGehee. The others Brewers teammates who had seasons with 60 or more extra-base hits:

1979 (four players): Cooper, Sixto Lezcano, Ben Oglivie and Gorman Thomas

1980 (four players): Cooper, Oglivie, Thomas and Yount

1982 (three players): Cooper, Thomas and Yount

1996 (three players): Jeff Cirillo, John Jaha and Jose Valentin

2005 (three players): Bill Hall, Geoff Jenkins and Carlos Lee

2007 (three players): Braun, Fielder and Hart

2008 (three players): Braun, Fielder and Hart

There have been 24 sets of teammates that had 70-plus extra-base hits in a season. The last time it happened was last year when Boston Red Sox players Jacoby Ellsbury, Adrian Gonzalez and David Ortiz each accomplished this feat.

In baseball history, there has been only six times when four teammates had 70-plus extra-base hits in a season. They were:

Year, Team, Players with 70+ extra-base hits

1996, Seattle: Buhner, Griffey, Martinez and Rodriguez

1996, Colorado: Bichette, Burks, Castilla and Galarraga

1999, Arizona: Bell, Finley, Gonzalez and Williams

2000, Anaheim: Anderson, Erstad, Glaus and Salmon

2007, Philadelphia: Howard, Rollins, Rowand and Utley

2008, N.Y. Mets: Beltran, Delgado, Reyes and Wright

Could Braun, Hart and Ramirez each reach 75 or more extra-base hits this season? Braun and Ramirez have a good shot, but Hart would have to collect 16 extra-base hits in the final 34 games. If the three should each reach 75 extra-base hits, they would become only the seventh such teammates to accomplish this in MLB history. The last trio to do so? The 2006 Phillies with Ryan Howard, Jimmy Rollins and Chase Utley.
