White Sox pitcher Jose Quintana laid an egg tonight. The Diamondbacks battered Quintana and sent him packing after 4.1 innings, slapping eight hits and scoring eight runs off of 76 Quintana pitches. Seven Diamondbacks struck out, but tonight was easily Quintana’s worst night of the season. His ERA leapt almost a full point and his record fell to 2-6.

Quintana has been uneven this year, as his last start was a one-hit gem. The ace is not only important to the White Sox on the field, but he is one of their best trade chips if the club decides to embrace a full rebuild. His trade value might be dinged after tonight, but manager Rick Renteria isn’t sweating it:

Sox manager Rick Renteria said he could foresee Quintana going on a run of strong starts.

“That wouldn’t be surprising to anybody — he comes in and all of the sudden you see four or five really good outings,” Renteria said. “We’ve all seen it before.”

The White Sox finished 3-7 on their West Coast trip.
