The obvious pick to me seems to be Madison Bumgarner ($11,900), who is facing the Phils, a team that is hitting just .235 with a .288 OBP against lefties. But my pick for the day is Hector Santiago ($7600). Santiago is having a solid enough year at 5-4, 2.40, but he is facing a Mariners team that is even worse (.227 average, .285 OBP) when facing lefties.
As for hitters, it is hard to not like the right-handed sticks of Toronto facing struggling lefty Danny Duffy, so I am going with Jose Reyes ($3400) and Jose Bautista ($5000), but I am also liking Luis Valbuena ($3100) against another erratic arm in Erasmo Ramirez.
Do note that rain is threatening in Kansas City and Colorado, and remember you can play for bragging rights against the Touts at the Tout Wars Challenge every Tuesday at Fan Duel.
