Orioles vs. Rays Prediction
Orioles pitcher Brandon Young is 9-3 with a 3.33 ERA, 1.32 WHIP and 93:41 K:BB over 113.2 innings. That looks like a good pitcher, but the underlying profile disagrees: a 15.8% strikeout rate, 10.7% walk rate, 40.9% hard-hit rate and a 5.31 xFIP. That's a soft-contact ERA waiting to correct.
Rays pitcher Freddy Peralta cuts the other way. He's at a 5.33 ERA and 1.50 WHIP with 121:50 K:BB across 123.1 innings in 24 starts. Additionally, Peralta has an 8.01 ERA over a nine-start stretch. Six of those contests came in under five inning performances.
Ultimately, I think the Rays are the better team by a wide margin. I feel comfortable in them winning the series finale at home, and I think the pitching matchup lends itself to a high number of runs on both sides.
- Pick: Rays, but only at a short price. Also lean over on the totals market today.
