The Arizona Diamondbacks were swept in a three game series by the Houston Astros this week, dropping their record to 50-53. That leaves them still 5.5 games out

The Arizona Diamondbacks are inching closer to selling at the trade deadline following Wednesday's loss to the Houston Astros.

The Arizona Diamondbacks are slipping out of the playoff race and will attempt to gain some traction when they hit the road to face the surging Pittsburgh Pirates in the opener of a three-game series Friday.

Outside of Gurriel, Eugenio Suarez is one player who has been receiving trade buzz over the past few weeks. He's let it be known as well that he wouldn't mind a trade, more specifically to the place where he started his career, the Detroit Tigers.

According to a league source, the Diamondbacks are scouting the minor-league systems of at least some of the teams interested in Suárez. Those teams, according to league sources and published reports, include the New York Yankees, Chicago Cubs, New York Mets, Cincinnati Reds and Seattle Mariners.

Christian Walker singled home the go-ahead run in the ninth inning and the Houston Astros beat the Arizona Diamondbacks 4-3 to complete a three-game sweep.

The Diamondbacks open a three-game series with the Houston Astros at Chase Field with Arizona's Zac Gallen facing Houston's Colton Gordon.

Similarly to Gallen, left-hander Eduardo Rodriguez showed flashes of a turnaround before falling back down to earth. After pitching to a 1.98 ERA in the month of June, Rodriguez has been knocked around for 13 runs in his last 8.1 innings.
