Freddie Freeman OVER 1.5 total bases (-105 DraftKings SportsBook)

Freddie Freeman will square off tonight against rookie Kyle Harrison and the San Fransico Giants. Harrison has shown some tendencies of reverse splits in his limited time in the big leagues, and although it is a small sample size, we will run with it. So far this season, Harrison has a .637 wOBA, .458 ISO, and a 41.7% hard hit against left-handed bats. Freeman is a lefty masher and has been even in his time in Atlanta. On the season against the split, Freeman owns an 182 wRC+, a .439 wOBA, and a .634 SLG. Since August 1, he has improved with a 185 wRC+, a .444 wOBA, and a .587 SLG.
