Guardians (-110) vs. Royals on the money line

Cleveland is just 2.5 games out of the last Wild Card spot in the AL and locked in a battle with the Rangers and Mariners — two teams who are also on winning streaks. The Royals, meanwhile, are four games back and have dropped three straight. Cleveland won the first game of the series 10-2 and the second game 2-0, so they will try to jump on Royals right-hander Jonathan Bowlan right off the bat. The SportsLine model projects Cleveland will be the money-line winner in 64% of simulations.  

Mets vs. Phillies over 8 runs

This bet paid out on Tuesday night as homeruns from Kyle Schwarber, Harrison Bader and Otto Kemp propelled the Phillies to a 9-3 victory. The Mets have now lost four straight and are in danger of falling out of the final Wild Card spot, so they should be eager to find the long ball — although that won’t be easy against southpaw Cristopher Sanchez and his 2.60 ERA. The Over is hitting in a whopping 72% of simulations by the SportsLine projection model. 

Cardinals vs. Mariners over 7.5 runs

The Mariners are clinging to the final AL Wild Card spot by 1.5 games, and their best bet against an inconsistent Cardinals team is to keep scoring runs. The Over has hit in three of the four games on the current winning streak, including Tuesday night’s 5-3 victory. The Over is hitting in 63% of simulations by the SportsLine projection model.
