"Of course you get conflicting reports," Yost said. "But we got one report that said it's just thunderstorms and then the next one we got was, 'OK, it's going to start raining about 4 and then stay 'til 10.' If that's the case, then we'll probably play a split doubleheader tomorrow."

As it turned out, the rain abated and the game began 55 minutes late at 8 p.m. ET.
