Derek Carty’s Diamondbacks vs Padres Preview, Prediction
I like Zac Gallen's pitching outs prop for tonight. The line opened at Under 18.5, but it flipped at 17.5 at plus money. So, if you're getting 17.5 at +130 or even +120, that will also do well.
The BAT X is projecting about 16 outs in this game for the Diamondbacks starter.
It will be Gallen's last start of the year. Guys tend to get less of a leash as we go deeper into the season, and in his final outing, he will not be throwing the same amount of pitches or the same amount of innings as he does in July. It just doesn't happen.
Gallen will be facing a good Padres lineup. There are several ways he can get under the line, whether it's his team deciding he will not go long into the seventh inning, or he gets hit around a little bit.
He's not efficient, so I like the Gallen under as a play for this game.
Pick: Zac Gallen Under 17.5 Outs (+132, bet365)
