Top MLB DFS building blocks for Monday.                                                      Monday's short slate offers plenty of great tournaments to choose from, and for those sorts of contests I'm building around a bargain pitcher. Tomlin's 6.86 ERA is the type of ugly statistic that will likely keep him low owned, but a 3.75 FIP and 3.34 xFIP mean that ERA rings hollow for me. Over the last two-plus seasons, Tomlin has been an elite option in terms of shutting down lefties (.220/.238/.395 against), and if he can continue that level of success, this Reds' lineup is going to put up little resistance. Even with the ugly ERA, Tomlin has been a 50/50 bet for a quality outing, showing me more than enough upside to roster him at this price point.
