Editor's Note: This written pick is a transcription from today's episode of the Payoff Pitch Podcast.

By Derek Carty

I'm looking at Sandy Alcantara under 18.5 outs. I posted it on the Action Network app earlier and got it at -115, but you'll need to look for the best odds available. I like it all the way down to -200, though.

Props of 18.5 outs are always really tough because pitching into the seventh inning is not easy for anybody. The Marlins ace has been doing it a lot lately, but he's facing a good Mets offense today.

The BAT X is projecting only about 17 outs for Alcantara, so I'm comfortable taking the under here. Hopefully he's out after he hits the sixth-inning mark.

Also, this time of year we tend to see starters not going as deep into games just because the season is almost over and they're getting a little fatigued. So there are definitely multiple ways we can win this.

Pick: Sandy Alcantara Under 18.5 Outs (-150, BetMGM | Play to -200)
