Arizona is sending minor leaguer Wei-Chieh Huang and another player to be named later.
Huang was the team's No. 22 prospect, per MLB Pipeline.
In corresponding moves, the Diamondbacks designated lefty Jorge De La Rosa for assignment and moved right-hander Shelby Miller to the 60-day disabled list. Spending the past three seasons with the Rangers, Diekman took to Twitter to express his gratitude after he was informed of the trade.
The 24-year-old Huang was a combined 6-2 with a 2.31 ERA in 29 games with Class A Visalia and Double-A Jackson this season.
Getting traded in the middle of an Major League Baseball season can prove something of a logistical nightmare for players, since they're usually expected to get all their stuff together and join their new teams - sometimes on the other side of the continent - by the next day. He is 3-2 with a 1.11 ERA in 35 appearances this season between Class-A and Double-A levels. He is 4-4 with a 3.57 ERA in seven big league seasons with Philadelphia and Texas. Springs allowed a run on one hit, a walk and a wild pitch, but recorded his first three career strikeouts in two innings of work.
Choo struck out again in the sixth inning, but returned to his slugging ways in the eighth, taking reliever Matt Andriese over the left-center field for his second long ball of the game.
