Rockies, 8, Diamondbacks 5

Money line (ML)

Slight “LEAN” to the ROCKIES (-150) for a quarter unit because the major takeaway from Frankoff’s profile is the fact that he’s a 32-year-old making his second start in the Majors and the presumed “sharp” money is on Colorado.

It’s tough to project Frankoff’s outing Friday given the little Major League. data we have on him, and for what it’s worth, Márquez is one of Colorado’s “top of the rotation” guys.

Furthermore, more money has been wagered on the Rockies while more actual bets have been placed on the D-Backs, according to

Typically, it’s more profitable in sports gambling to follow the money, especially when it’s flowing in the opposite direction of the crowd.

Run line/Against the spread (ATS)

PASS because Colorado has an 8-15 run line record as a home favorite since the beginning of last season and the Rockies -1.5 (+115) is too measly of a payout in the face of that trend.

My “lean” towards Colorado has mostly to do with Márquez having decent stuff and not knowing what we’ll see from Frankoff.

But, both lineups and bullpens are equally as bad. Colorado’s run line should have at least a +130 payout, in my opinion.

Over/Under (O/U)

“LEAN” to the OVER 11 (-115) for a half unit since we are getting the worst of the number as the market has barreled into the Over, steaming it up from the 10.5-run opener.

However, this is still the launching pad of Coors Field, both bullpens get nuked on a regular occasion, the Rockies have a 6-3 O/U record in Márquez starts and the Over has cashed in seven of the past 10 Rockies-Diamondbacks meetings.
