Tyler Anderson isn't having a great year and has been extremely homer prone, but the Mariners are one of the worst teams in the league against lefties, posting a .593 OPS against southpaws that only ranks ahead of the Padres. Mariners lefty Ariel Miranda has been solid over his last few starts, but Coors is a different beast, and the Rockies rank sixth in OPS against lefties. The Rockies have put together an excellent May, posing a plus-50 run differential in the month. This is a nice value with this team.

Got burned with the Rockies on Monday, but going back to the well behind Tyler Anderson, who's allowed two or fewer runs in three of his past four starts. Look for Colorado to improve to 12-5 in its last 17 games against left-handed starters.

I'm projecting 9.3 runs for Mariners-Rockies on Tuesday night, giving us a strong lean to the Under. The Under is cashing in 65 percent of my simulations.
