The Arizona Diamondbacks have been snakebit all season. Injuries plagued the club in spring training and have continued to wreak havoc as the season reaches the midpoint, leaving manager Torey Lovullo searching for answers as he tries to cobble together a daily lineup. Left-hander Corbin Burnes, signed to a $210 million, six-year deal in January, lasted 11 starts before going down with a season-ending elbow injury. Reliever A.J. Puk also needs elbow surgery, to repair his left ulnar collateral ligament, a procedure that could turn into Tommy John.
