Rawlings 2017 World Series baseball

The baseball used in the 2017 World Series is pictured in St. Louis on October 31, 2017. Pitchers with the Los Angeles Dodgers ad Houston Astros have complained that the baseballs used in this postseason are different and slicker than normal. Major League Baseball commissioner Rob Manfred has denied that the balls are different and claims the baseballs are the same as the regular-season version. Many pitchers say the ball has been flying excessively resulting in a record number of home runs in this World Series. Photo by Bill Greenblatt/UPI
