I'm by no means a master of roto leagues, in fact I've only played in points leagues, but let's see what I can come up with.
Your outfield is already doing pretty good, and what with the way Heyward was playing before the injury it's not as though he'd DEFINITELY get slotted into your lineup. That said, Hamels (I own him too) has just been okay. Not great, but not terrible either. He's definitely striking guys out though. Pretty much 9K's/9inn right now. Judging by your rotation though, I'm guessing you're already pretty solid in the K's department.
How many SP can you play (again, as I mentioned I'm a little unfamiliar with roto leagues). Are you even going to be able to play Hamels with any regularity? I mean he'd really be no better than your 4th best pitcher, and likely more like 7th (Wainwright, Sabathia, Gallardo, & maybe Hanson, Nolasco, and Hughes are all better than him). If you can't play him, or he's barely ever going to see playing time, I'd say hang on to Heyward and hope he comes back healthy and studly. If you think he's definitely going to get regular playing time in your lineup maybe you do the deal, because like I said it's not like Heyward was lights out in June.
My final assessment is this... I say you don't bother. Your rotation seems pretty stacked already, and Hamels wouldn't make it that much better. But if you catch lightning in a bottle and Heyward comes back healthy and kicking butt, then I could see him making your team pretty dominant.
