Providence Grays centerfielder Paul Hines catches a fly by Jack Burdock and starts a triple play, racing in to touch third base before Jack Manning can return, then throwing to second to nab Ezra Sutton. Some eyewitnesses contend that Sutton had passed third and was out when Hines touched the base, making it the only unassisted triple play by an outfielder. This contradicts the version by Manning, Jim O’Rourke and others present, which has been accepted generally as the correct account.
