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.

Garcia is a 25-year-old left-hand relief pitcher the Diamondbacks just acquired from the Seattle Mariners as part of a trade that sent Josh Naylor to Seattle. Arizona also acquired right-hand starter Ashton Izzi in the deal, but he is in High-A Hillsboro to start his Diamondbacks career.

The Diamondbacks are reeling and look to be sellers at the trade deadline. The Mets could use another starting pitcher. This seems like a match between the two.

Diamondbacks starter Ryne Nelson fired six innings of one-run ball against St. Louis over the weekend in his first start out of the All-Star break.

Infielder Luis Guillorme began a minor-league rehab assignment Wednesday with Triple-A Sugar Land in his recovery from a right hamstring strain. Guillorme was placed on the 10-day injured list July 2, after playing in 12 games with the Astros as a utility infielder.
