Superman can just grab his opponent & fly to the sun, end of battle.

With the recently announced news of Superman/Batman, the whole idea of them clashing has again become a popular topic. Thing is, there's no Kryptonite in this universe so it got me thinking, just how could Batman hurt Superman? I'm not really sure how there would be much of a fight anyway, seeing as how if Superman landed one punch Batman would be eating through a straw if he survived. So, how else could he hurt him without physically engaging him in a brawl or otherwise silly mechanism or robot? I'm not hating, I love both characters to death I'm just curious.
