Was there any update as to why Sheets was scratched? Because really, there is no remotely close comparison to starting Gavin Sheets vs Adam Haesley....
Seby is a 150 hitting catcher going nowhere. And he'd be the primary guy at that point. I don't think anyone wants to see Seby and Alberto as 8-9 in the order for 2-3 weeks etc.
Hopefully Yaz isn't hurt for an extended period of time.
