Thinking of combining Halep and Vinci with Kohl and Verdasco. Not worried about the ladies-they are heavily favored for a reason, and should take out their respective opponents in straights-but what about the men? Kohl should win at home with the crowd behind him, no? And sizzling Verdasco certainly looks good against Mr. Sharapova? I've even considered the -2 at + odds for that one. I don't do parlays very often, especially in tennis, but this seems like a good one to me. Any thoughts or advice?
