The Pirates left the All-Star break as wild-card contenders, but they now appear headed toward a Mets-like collapse. Even so, there's no reason they should be this big of an underdog Friday against a New York club that doesn't have one of its aces on the mound. Zach Wheeler is the subject of trade rumors, which could be a distraction. He is 3-2 with a 4.71 ERA at home and yielded six earned runs in his last outing. Pirates rookie Dario Agrazal has allowed two or fewer earned runs in each of his five starts.
