Win loss record is irrelevant on a bad white sox team. ERA is perhaps concerning but his last 7 starts he's posted a 2.70 ERA, 3.40 FIP, 3.52 xFIP and a 27.1 K%. His ERA really comes down to 4 terrible starts. 2 in april(4th and 15th giving 6 and 5 ER) and 2 in may(24th and 30th giving up 8 and 7 ER). I know you can't entirely cherry pick data like that but if you remove those 4 starts he's given up 26 runs over 86.1 innings for a 2.71 ERA.
edit: brett or some of our other sox fans probably can provide more info than I can as to what was going on there but the first two in april seem like just normal early season adjustments. The 4th was his first start and the 15th was his third. They weren't that terrible really. The 2 starts in may were back to back @arizona which is never fun to pitch at and at home vs a pretty good boston team. Probably a case of him not having a good feel for his pitches for about a week. Two starts before and after were 8 innings of 1 hit ball vs seattle and 5.1 innings of 4 hit ball vs Tampa. Gave up 1 ER in each.
Q didn't get ST like others did and was rushed because of the WBC. That basically speaks of his slow start. I didn't hear anything about him having troubles in May, the truth is at times pitchers get rocked. It happens. However, you look at his numbers since Jun 1st and they are even better than his career norms. He's actually pitching better now. I was most impressed with his start in Colorado where he basically man handled a great hitting team in a great hitting park.
You all give him some offense and those that are hung up on wins will see that drastically increase.
As Hahn said yesterday, for a guy that has 65ish non decisions he never complained about the bullpen imploding or the fielders not making the plays. He was class all the way thru.
I am going to say this now at the risk of getting laughed at by the respectable people here on the Cubs board. He's Ryne Sandberg when it comes to leadership. Rizzo just got edged out. You'll here more about Rizzo, but Q is your leader. Quiet, behind the scenes, but the leader. It's not something the Cubs needed. Rizzo is a gem in my eyes. But he's going to be your guy. I hope he gets some Cy love for a couple of years he has left with you all. He's all around with age, durability, contract, stuff, and outside things a top 5 pitcher in the game.
