The Arizona Diamondbacks have been an active team at the MLB trade deadline, and Merrill Kelly or Zac Gallen could be the next to leave.

PITTSBURGH — The Diamondbacks have traded outfielder Randal Grichuk to the Kansas City Royals, a source said, the second veteran position player the club has dealt ahead of next week’s trade deadline.

Major League Baseball's trade deadline is scheduled for next Thursday, which means teams have less than a week to get their midsummer shopping done. The moves have already started, as the Mariners recently acquired Josh Naylor from the Diamondbacks while the Yankees acquired Ryan McMahon in a trade with the Rockies.

Despite Merrill Kelly only conceding one earned run, the Diamondbacks couldn't muster anything offensively in a 2-0 loss at the Pittsburgh Pirates on Saturday.

As the Arizona Diamondbacks prepare to face the Pittsburgh Pirates this weekend, the club made a pair of key roster moves that further signal their shift toward selling at the upcoming trade deadline. Right-hander Trevor Richards has been designated for assignment, while left-hander Brandyn Garcia has been recalled from Triple-A Reno.

The Philadelphia Phillies have an intriguing MLB trade deadline coming up, and with many decisions to make, one of their biggest targets could cost a lot.
