| Team | Win Probability |
|---|---|
| PHI @ LAD | PHI 48.5% / LAD 51.5% |
| CHC @ STL | CHC 56.4% / STL 43.6% |
When analyzing where to allocate your shares in the CHC @ STL matchup, a quick statistical comparison gives Chicago a quantifiable edge, justifying their 56.4% implied probability. Offensively, both clubs are batting exactly .238 on the season, but we’ve seen time and time again that run creation matters more than empty average. The Cubs hold the advantage in team OPS (.725 to St. Louis’s .701) and have plated more total runs (265 to 235).
On the mound, the team ERAs are nearly a wash (Chicago at 4.225 vs. St. Louis at 4.216). However, the Cubs’ pitching staff has been much more efficient at limiting traffic, boasting a 1.24 team WHIP compared to the Cardinals’ 1.37. Given their better run production and superior control from the mound, it does stand to reason that the Cubs are the smart, analytical prediction today.
