Today's Playbook covers the all-day slate around the industry. Sundays can be very weird as non-regulars find their way into the lineup with much greater frequency during the day games on Sundays. That can make things very tricky on sites like FanDuel which don't allow for lineup swaps after the first game of the slate starts. It's probably best to invest left on those sites when playing an all-day slate. For cash lineups, try to focus on players already confirmed in early lineups or players that rarely sit in the later afternoon games. 

As far as weather concerns go, the biggest concerns are on the south side of Chicago and in Detroit. As of this writing (in the wee hours of the morning on Sunday), the Detroit game looks likely to be postponed. That could certainly change, but since that's the Sunday night game anyway, it should be avoided completely. The Angels-Rangers game looks like it could see a delayed start, and the game in Cincinnati could run into some issues later in the game, but those situations will have to be monitored closer to game time.

As for stacks, Vegas has Toronto with the highest projected run total of the day. Shocking. But against Steven Wright, it's hard to disagree. You can always fade them in tournaments if you like, but exposure to them in cash seems necessary. Vegas also like Pittsburgh and Boston. Pittsburgh will be facing a starter making his major league debut, and Boston will face Marco Estrada. Again, hard to argue with Vegas. Of the two, I'm more inclined to use Boston. Baltimore would be my under-the-radar stack of the day.
