Jon Hamm may have found a role that fits him as well as Don Draper’s suits in “Mad Men.” He’ll star in “Million Dollar Arm,” based on the true story of J.B. Bernstein, a sports agent who signed two teen cricket players, Rinku Singh and Dinesh Patel, discovered in a 2008 reality TV show to find the fastest-throwing phenoms in India. Hamm teaches them baseball and gets them signed to the Pittsburgh Pirates. The feel-good film will probably leave out that Patel was cut in 2010 and Singh is still in the minors.
