ESPN's "Outside the Lines" has conducted a study to get a sense of how often umpires made the right call on close plays. Researchers used broadcast footage of all games from June 29 to July 11 -- 184 in total -- and reviewed every call aside from balls and strikes. The "Outside the Lines" analysis found that an average of 1.3 calls per game were close enough to require replay review to determine whether an umpire had made the right call. Of the close plays, 13.9 percent remained too close to call, with 65.7 percent confirmed as correct and 20.4 percent confirmed as incorrect. "That's high," said U.S. Sen. Jim Bunning, a Hall of Fame pitcher. "They shouldn't be allowed to miss [that many]. "I have seen some calls this year that just -- that curl your hair."
