During his 11-game absence because of vertigo, pitching coach Don Cooper was forced to watch the White Sox’ games on television. Even with the separation, he saw things that impressed him. ‘‘You might accuse us of a lot of things, but it’s not for a lack of effort, fight, competing — I see that happening,’’ said Cooper, who returned Friday night. ‘‘You get a little different perspective on TV. So there’s a lot to be happy about with our team and players.’’ The Sox showed a lot of what Cooper was talking about in a 10-8 victory over the Minnesota Twins. ‘‘They’ve been fighting like this for a while — offensively, just grinding out at-bats and being able to put it together,’’ manager Robin Ventura said. ‘‘I think even if you get down, they’re still feeling like they have a shot, and I think as soon as a guy gets on, they feel like stuff’s going to happen.’’ They needed that attitude after their best pitcher had a rare off night. Ace Chris Sale gave up five runs and eight hits in six innings. His ERA rose from 1.88 to 2.09, and the four earned runs he allowed in a five-run third matched his highest total for any start this season. On a night like that, you’d think it would be tough for the Sox to continue the momentum from a 5-2 road trip that saw them take series from the Twins and the first-place Detroit Tigers. Sale’s outing was perhaps his worst of the season and could have deflated his teammates.
