YES

The Orioles (69-70, away) are significantly better than the Rockies (53-86, home). Sportsbook consensus gives the Rockies a 43.7% win probability, implying Orioles at ~56.3%. The Orioles have a much better record. Kyle Bradish (Orioles) vs Gabriel Hughes (Rockies). The Rockies' poor record supports the Orioles as favorites. Adjusting slightly from the sportsbook implied probability, I estimate ~56% for Baltimore winning.

Baltimore is the better team by record (69-70 vs Colorado 53-86) and appears to have the stronger starter in Kyle Bradish versus Gabriel Hughes, which points toward the Orioles despite being on the road. However, Colorado is at home, and the sportsbook consensus still gives the Rockies about a 43.7% home win chance, implying Baltimore around 56.3% before vig. I trim that down a bit for uncertainty around starting pitcher quality/availability and normal baseball variance, landing at 45% for a Baltimore win.
