Tampa Bay Rays 
at New York Yankees 
Shane McClanahan has been almost unstoppable this year, posting a 1.76 ERA and 1.13 WHIP while recording the win in seven of his eight starts. He also logged a 1.50 ERA in 18.0 innings vs. the Yankees last year. Meanwhile, Nestor Cortes has seen his form drop off this year (though he's still been good at home), going past five innings just twice in seven starts while allowing multiple runs in all but one game. The Rays themselves are 6-1 vs. LHP, while the Yankees are 5-4 vs. LHP. Clear edge for Tampa today at the pick 'em price.
MLB Best Bets for Rays at Yankees
- Tampa Bay Rays F5 -0.5 (FanDuel -108)
Seattle Mariners 
at Detroit Tigers 
Rookie Bryce Miller has looked sensational since his callup a couple of weeks ago, pitching six innings in both starts while allowing just five combined baserunners and one earned run over the 12.0 innings. He now gets a nice spot vs. the Tigers and their starter Alex Faedo, who allowed two homers over 4.2 innings in his only start this year. The price is reasonable to back what looks like one of the game's best young pitchers vs. an inferior opponent.
Miller's stuff has looked tremendous (particularly his fastball), helping him record 10 strikeouts in his major league debut vs. Oakland and then log five (over six innings) vs. the low-strikeout Astros his last time out. He's in a good spot today vs. the Tigers, who rank in the upper third of the league in strikeouts on a per-game basis. It's even possible Miller goes a bit longer than six innings today, as he still hasn't topped 85 pitches yet.
MLB Best Bets for Mariners at Tigers
- Seattle Mariners F5 -0.5, (DraftKings -125)
- Bryce Miller over 5.5 strikeouts, (FanDuel +128)
San Diego Padres 
at Los Angeles Dodgers 
I'm always interested in taking Julio Urias at a coin-flip price at home, and it helps that the Dodgers are 17-9 vs. RHP in addition to being 13-6 at home. Also note that Urias has a 1.82 home ERA over 24.2 innings. It's a cheap price here on a likely result.
MLB Best Bets for Padres at Dodgers
- Los Angeles Dodgers F5 -0.5, (FanDuel -105)
