Let’s take at the game winner probability of a couple of the best MLB games to dive into on the Saturday slate:
| Matchup | Probability |
|---|---|
| SEA @ DET | SEA 55.45% / DET 44.55% |
| SF @ CHC | SF 44.17% / CHC 55.83% |
| CHW @ PHI | CHW 45.32% / PHI 54.68% |
When looking at the numbers behind the Giants and Cubs matchup to pinpoint the smartest prediction, pitching tells a major part of the story. The Cubs boast a tighter pitching staff with a 4.175 team ERA, notably outperforming San Francisco’s 4.584 ERA. At the plate, the Giants hit for a better average overall (.256 compared to Chicago’s .240), but we put a lot of stock in the fact that the Cubs generate more overall production with a slight edge in OPS (.724 to .712). Chicago’s combination of run prevention and on-base plus slugging makes them a highly justifiable favorite at home.
