Welcome to our best NRFI bets today for Friday, Aug. 15.
We swept the slate last night after what was mostly a .500 week - it's time to do it again with one play we are loving heading into this fine Friday night.
We now sit comfortably with a 65-50 record (+4.28u) on the year. Let's dive into my first-inning picks and predictions for today using odds from our best sports betting sites.
All of these plays are one-unit wagers unless specified otherwise.

⚾️ Mariners vs. Mets - 7:10 p.m. ET
Luis Castillo (3.19 ERA) vs. Sean Manaea (4.33 ERA)
NRFI record: Mariners (63-59) vs. Cubs (70-51)
This is a case of two pitchers who perform well in this specific matchup, and so you better believe we're riding them as part of our best NRFI bets today.
Castillo has given up just five earned runs across his last three starts, two of which he pitched seven strong innings. He's been a cash cow for us this season, and the Mets own just a .219 xBA against him, which includes paltry numbers from Juan Soto (2-for-10) and Pete Alonso (1-for-11).
Manaea takes the same approach while dominating the top end of the Mariners' lineup. Eugenio Suarez (1-for-9), Cal Raleigh (0-for-4), and Josh Naylor (0-for-3) have all been enduring a difficult time against the left-hander, which should lead to three simple outs.
I'd price this play closer to -130 betting odds than the -115 we're getting at DraftKings, giving us a ton of value. Let's ride this one with confidence heading into the weekend.
