Philadelphia Phillies vs Colorado Rockies Best Bets and Predictions

The biggest pitching mismatch on the slate is Jesus Luzardo versus Antonio Senzatela, but it also comes with a very hefty price tag of a -270 moneyline on the road, but the total is reasonable at 10.5. A lot of that total though is the strength of Luzardo against this weak Rockies lineup. So that means we have to go shopping for something of value that makes sense preferably between the -120 to +120 price range.

The -1.5 run line is -190 Phillies, and the 2.5 run line is -132, which might be doable, but man this is getting out of hand and rightfully so with how bad Colorado is right now. 

My first go-to is usually the team total, and then I start looking at F5 team totals. 

Here are some potential F5 options - Rockies under 1.5 runs, Phillies over 3.5 runs, Phillies -1.5 

I am going to roll with the Phillies at -1.5 runs F5 and Phillies over 3.5 runs F5. I normally stay away from doing this as I have been burned in the past, but they are at good prices.  

MLB Best Bets: Phillies -1.5 runs F5 for 1 unit (DraftKings -105); Phillies OVER 3.5 runs for 1 unit (DraftKings +100)

Cincinnati Reds vs Pittsburgh Pirates Betting Insights

I have been taking under in Pirates games for a while now, and nothing changes here as we get Nick Martinez against Bailey Falter. The key is here we get two offenses in very bad situations. The Reds are a bottom 5 offense against left-handed pitching. 

  • The total has gone UNDER in 8 of Cincinnati's last 8 games.
  • The total has gone UNDER in 8 of Cincinnati's last 10 games on the road.
  • The total has gone UNDER in 5 of Pittsburgh's last 6 games.
  • The total has gone UNDER in 5 of Pittsburgh's last 6 games against Cincinnati.
  • The total has gone UNDER in 6 of Pittsburgh's last 6 games at home

The Pirates have averaged 2.4 runs per game in their last 10 and the Reds have averaged 4.2. The total is already moving towards 7.5 at some sportsbooks which is usually an indication of where things will be heading. 

MLB Best Bets: Reds/Pirates UNDER 8 runs for 1 unit (BetRivers +107)

Texas Rangers vs New York Yankees Best Bets and Predictions

The Yankees average the third most runs per game at home in baseball at 5.9 and get Patrick Corbin tonight who has pitched relatively well this season. But I can not trust Corbin in this spot against a Yankees lineup that is #1 at home against left-handed pitching with a 185 wRC+. 

MLB Best Bets: Yankees OVER 4.5 runs for 1 unit (DraftKings -130)
