We know what we're likely to get with White Sox starter lefty Jose Quintana and that's a quality start. Quintana is one of the more respected pitchers in baseball. The White Sox have won four of Quintana's past five starts.

But what are the Diamondbacks going to get from their starter today, Randall Delgado? They're hoping for maybe five solid innings. Delgado hasn't started in two years. He has a 4.05 ERA and is part of a bad and untrustworthy Diamondbacks bullpen that figures to see a lot of innings as this shapes up as a bullpen-by-committee game. Delgado is filling-in for Taijuan Walker, who is on the DL due to blister issues.

I'd much rather have Quintana going for me then some Arizona combination of Delgado, Tom Wilhelmsen, Jorge De La Rosa and T.J. McFarland.

Yet, Arizona opened the favorite. The Diamondbacks have a losing record versus lefties. They are 2-5 the last seven times facing a southpaw starter.

Another key here is motivation. It's only fair to point out Arizona has the best home record in the majors at 20-8. The White Sox, though, will be looking to avoid a sweep. Quintana certainly should be motivated as he's prime trade bait and a heavy dose of scouts throughout both leagues will be watching him.
