Starting pitcher matchup
Full Pitcher Matchup Tool →| Metric | Nationals | Phillies |
|---|---|---|
| Pitching plan | Opener / bullpen game | Traditional starter |
| Expected innings | 2.1 | 5.8 |
| Throws | L | L |
| LyDia pitcher score (higher is better) | 43 | 72 |
| BB/9 (lower is better) | 3.9 | 2.9 |
| HR/9 (lower is better) | 0.6 | 0.8 |
| Ground-ball rate | 36.7% | 59.6% |
| IP per start (higher is better) | 2.1 | 5.8 |
Pitching plan edge: LyDia gives Jesús Luzardo the edge over the Washington Nationals pitching plan (7 points on LyDia's pitcher score). Carson Palmquist is projected for only 2.1 innings, with the Washington Nationals bullpen covering the rest -- this compares Jesús Luzardo's own line against the Washington Nationals blended starting-pitcher-and-bullpen quality, not two starters directly.
Blended read: For the Washington Nationals, the bullpen is projected to throw more of the game than Carson Palmquist (about 2.1 innings for the starter), so LyDia grades that side on a whole-game effective ERA of 4.19 rather than Carson Palmquist's own 7.31. Whole-game, that is 3.32 for the Philadelphia Phillies against 4.19 on the other side, so the blended read leans Philadelphia Phillies.
How to read this: the scorecards show ERA, WHIP, K/9, and K-BB%. The table adds complementary traits without repeating them. Highlighted cells mark a gap big enough to matter. HR/9 is home runs allowed per nine innings. Ground-ball rate is neither good nor bad on its own: high ground-ball pitchers trade strikeouts for double plays and fewer home runs.
Strikeout Projections Full strikeout projections →
Projections are self-calibrated against graded results (150 graded starts). Official K picks are taken from LyDia's locked published card, which requires a 0.7+ strikeout edge, a posted price from at least two books, a confirmed non-opener workload of at least four expected innings, and a posted starting lineup. Plays shown here that are not on the card are qualifying projections only.

Bullpen matchup
Full Bullpen Fatigue Index →Risk is what the model actually uses: fatigue blended with how well the pen has pitched. High fatigue with high efficiency is a tired pen that is still getting outs.
| Metric | Nationals | Phillies |
|---|---|---|
| Fatigue | 4.0/10, Normal | 6.8/10, Tired |
| Efficiency | 4.2/10, Below average | 5.8/10, Effective |
| Combined risk | 4.4/10, Normal | 6.4/10, Tired |
| Relief innings, last 7 days | 18.7 | 17.0 |
| Back-to-back arms | 4 | 6 |
| 7-day ERA | 5.30 | 3.18 |
| 7-day WHIP | 1.39 | 1.18 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
Run total projection
Full Totals Projections →The model projects 2.5 runs below the market total. A research lean still requires a setup rating of at least 7.0/10. Team totals remain research-only until their graded sample is established.
