The Arizona Diamondbacks have made an art of the comeback, rallying for victories 30 times in their first 112 games. No. 31 might have been the most impressive -- and improbable -- of the bunch. Martin Prado hit a two-run single in the eighth after Arizona blew a three-run lead the inning before, helping the Diamondbacks rally for a 9-8 victory over the Tampa Bay Rays on Wednesday night.
