Profiled after All Star Joe Mauer's game-day model, this 2015 Rawlings Big Stick Birch Wood Baseball Bat (JM7BIR) provides players with a huge barrel that creates more momentum in a player's swing and extends the length of the sweet spot. For some players, an evenly balanced bat is a better fit, but the increased mass in the barrel of a Big Stick is the perfect tool for long-ball hitters to send the ball flying all over the yard. Each 2015 Rawlings Big Stick Birch Wood Baseball Bat (JM7BIR) is cut from Flame Treated Birch wood. The flame-treating process not only creates a distinct and classic finish on the bat, but it also burns off raised dead wood fibers leaving only the hardest, most responsive wood behind. The finishing touch to this bat is the new Ultra Thin Tac-Grip that surrounds the 31/32 inch handle for enhanced feel and ideal comfort.
