The Pirates vs. Royals Showdown: A Tale of Two Struggles
The Kansas City Royals (44-48) and Pittsburgh Pirates (38-54) meet in the rubber match of their series, with both teams serving as baseball’s version of a broken umbrella in a hurricane.

The Verdict
While the Royals’ “hot bats” and Bubic’s ERA might seduce you, the math tells a different story. The Pirates, despite their 38-54 record, offer a +6.5% edge as underdogs, and the under 8.5 runs has a +5% edge.
Best Bet: Pittsburgh Pirates (+260) ML
Secondary Play: Under 8.5 Runs (-110)
Why?
- The Pirates’ 39% underdog win rate (25/64) is just 2% shy of the MLB average (41%), giving them a slight edge.
- Bubic’s recent struggles (5.12 ERA in last 3 starts) and the Royals’ anemic offense (67 HRs) make them overrated favorites.
- The under is a no-brainer in a matchup of two teams that hit like they’re playing with wooden bats.
Final Thought:
The Royals might sweep this series, but the Pirates are the smarter bet. After all, as the old saying goes, “The best thing about a Pirates win is that it’s not a loss.”
Go with the Pirates (+260) and the Under 8.5 Runs (-110).
