Ben Rice has 6 home runs over his last 14 games on the road," SportsLine data analyst Jacob Fetner said. "Ben Rice has the platoon advantage against right-handed Davis Martin and has been absolutely dominant against right-handed pitchers this season, boasting a .282 average with a 1.010 OPS in 279 PA, with 22 of his 31 HRs coming off right-handed pitching this season."

Now they can clinch a series win on the road against their arch rivals and Matthew Boyd has been pitching well of late. He's gone at least six innings and allowed one earned run or fewer in three of his last four starts. Cardinals starter Dustin May, on the other hand, has a 4.59 ERA on the season. The model predicts that Chicago wins in 57% of simulations.

Heck, I'd probably play this line up to at least -200. Since coming over to Los Angeles, the Dodgers are 8-0 when Lauer pitches for them," SportsLine MLB expert Eric Cohen said. "Not to mention that current Mariners hitters are only 7 of 41 against him (.171 average). Until this fad loses, I'll keep playing it over and over again."
