The Diamondbacks are dealing at the trade deadline, and their latest move sees them part ways with a starting pitcher.
Ahead of the 6 p.m. deadline, Arizona traded Merrill Kelly to the Rangers. Kelly made his professional debut in Korea but has not suited up for any other MLB team but the Diamondbacks after making his major league debut at the age of 30 in 2019.
Kelly is a very valuable pick-up for Texas, as he was one of the more coveted starting pitchers on the trade market.
