Orioles vs Diamondbacks, Odds & Picks: Gallen Welcomes O’s to Desert cover


No time to read? See our free statistics and matchup

The Arizona Diamondbacks are hosting the Baltimore Orioles in the desert in the final game of this three game standalone series between these teams.

Both are in an intense battle for playoff seeding, so both teams will come to play tonight.

The Diamondbacks are tied with the Giants for 2nd place in the NL West, but both are 2 games behind the Chicago Cubs for the 2nd Wild Card spot.

In the American League, the Orioles lead the AL East by 2.5 games over the Tampa Bay Rays, but they will want to extend that league as the season comes to a close.

Let’s break this game down!

Orioles vs Diamondbacks Best Bets

Orioles Diamondbacks Odds Picks

Neither of these teams have seen these other pitchers too often, and nobody has outstanding numbers either.

With both teams needing this game for playoff implications, I can’t seem to get a read on how this one will pan out on the scoreboard.

But plain and simple, I think Gallen gets back to shoving tonight.

Even against this Orioles offense, Gallen is a different animal at Chase Field.

Let’s discuss.

Orioles Diamondbacks Odds Picks

Let’s start by talking about this guy’s splits.


  • 3.32 ERA
  • 1.10 WHIP
  • .234 Opp Avg
  • 1.05 K/Inning

Now let’s look at his stats at Chase Field.


  • 1.79 ERA
  • 1.07 WHIP
  • .187 Opp Avg
  • 1.15 K/Inning

The dude simply comes to play at home. Gallen clears 6+ Ks in 11/13 home starts this year, posting double digits four separate times.

He also had 11 in his last start at home, and he’s cleared in 3 straight home games.

Overall, Gallen has only hit this number once in his L3 starts, but he’s cleared in 61% of starts this season, and in 5 of his L7 overall.

At home tonight, I don’t see him having a problem against an Orioles team that has struck out more to RHP over the last month.
