"We have been working on this idea for several years and there's no more appropriate time to bring back the bullpen cart than this season, as we celebrate our 20th anniversary," Diamondbacks President Derrick Hall said.
"We lost an important member of our family and someone I personally love dearly," Diamondbacks President Derrick Hall said in a statement. "He was one of the biggest personalities the game has ever seen, with a heart of gold and an eye for talent. He could not get enough of baseball, and baseball could not get enough of our KT. It is no surprise he fought for extra innings. Our love goes out to Kelley, his family and everyone who knew him."
