Observation from a Sox fan.
Cubs will win the division if Soriano hits like a 18 milion dollar player, Soto hits like his rookie year, Lee and Ramirez stay healthy, and Marmol can settle into at least a decent closer.
Sounds like a lot, but well within the relm of possibility.
Side note
Marmol found the hole in Heywards swing, start a curve ball over the plate and let it run down and in. Three misses for Heyward, made him look like a bad rookie not ROY.
