Philadelphia enters with plenty of momentum after winning its last four games, including a solid victory against the Angels.

Phillies vs. Diamondbacks Pitching Matchup
Aaron Nola takes the mound for the Philadelphia Phillies carrying a 5-10 record this season.
Nola owns a 5.03 ERA and has accumulated 153 strikeouts. Despite that strong strikeout total, his overall performance has been inconsistent, something reflected in his win-loss record.
Brandon Pfaadt gets the ball for the Arizona Diamondbacks on the other side.
Pfaadt enters with a 7-1 record and a 3.51 ERA, showing much more stability throughout the season. His 72 strikeouts may not match Nola’s total, but his ability to limit runs has been an important part of his success.
Nola’s 1.40 WHIP further reflects some of his challenges with allowing baserunners. That has been a factor in his struggles throughout the season. He will need stronger control in this matchup if he wants to produce a better result.
Pfaadt carries a 1.14 WHIP, showing he has been more effective when it comes to limiting baserunners. That efficiency has contributed to his impressive win-loss record. He will look to maintain that same level of control when he takes the mound against Philadelphia.
Philadelphia Phillies vs. Arizona Diamondbacks bottom line: Philadelphia arrives at Chase Field carrying the better recent form, while Arizona has been strong at home and already holds the edge in a tightly contested season series.

Phillies Diamondbacks Free Pick: Under 8.5
Here is my Phillies Diamondbacks free pick: Philadelphia is playing winning baseball right now, and the recent scoring patterns in this matchup have me looking toward a quieter game. I’m taking the under.
The Phillies have won 4 of their last 5 games, with 3 of those contests staying below the total. That’s a useful combination when we’re looking for a team to control games without needing huge offensive production.
Arizona has gone over in 3 of its last 5, so the Diamondbacks’ recent totals tell a different story. However, the head-to-head trend between these clubs has leaned toward lower-scoring results. That carries weight.
Recent meetings between Philadelphia and Arizona have regularly stayed under, giving me confidence in another controlled scoring game.
The Phillies’ recent success also fits this handicap because they’ve been finding ways to win while keeping scoring manageable. No fireworks needed.
Can Arizona turn this into the kind of game that blows past 8.5?
Maybe, but I’m betting the matchup history wins out. Additionally, Philadelphia’s recent under trend gives us another reason to expect pitching and defense to have a bigger influence than the bats. Arizona doesn’t need to be completely shut down either; we just need both clubs to avoid the crooked innings that can wreck an under quickly.
My MLB betting system points to the Under 8.5, and I’m trusting the recent scoring trends in this matchup.
