### The Pythagorean Theorem & Expected Win %

Based on early 2026 season data, we calculate the expected win percentage to see which team is over- or under-performing their actual record.

• Arizona Diamondbacks (16-13): With 134 Runs Scored (RS) and 150 Runs Allowed (RA) through 29 games, their Pythagorean win percentage is:

  $$Win\% = \frac{134^{1.83}}{134^{1.83} + 150^{1.83}} \approx 0.444$$

  • Insight: Arizona is currently over-performing their run differential by roughly 3 games.

• Milwaukee Brewers (15-14): Averaging 5.0 RS/G and 4.41 RA/G, their expected win percentage sits at:

  $$Win\% = \frac{145^{1.83}}{145^{1.83} + 128^{1.83}} \approx 0.556$$

  • Insight: Milwaukee is slightly under-performing their statistical profile, suggesting they are due for positive regression.

### Pitching Matchup: Soroka vs. Woodruff

• Michael Soroka (ARI): A dominant 4-0 start with a 2.60 ERA. He has been the Diamondbacks’ anchor, though his FIP suggests some regression may be coming as he relies heavily on ground balls.

• Brandon Woodruff (MIL): Carrying a 2-1 record with a 3.77 ERA. Woodruff is the superior strikeout pitcher (9.2 K/9) and historically performs significantly better at American Family Field.

### External Factors & Injuries

• Arizona Injuries: The D-backs are missing key offensive components. Gabriel Moreno (Oblique) and Carlos Santana (Adductor) are on the IL, which weakens their middle-order protection for Ketel Marte. Zac Gallen is day-to-day but not starting today.

• Milwaukee Injuries: The Brewers are without Jackson Chourio (Hand) and Andrew Vaughn (Rehab), but they have seen a surge from Tyler Black (.357 AVG) and Brice Turang, who has been a menace on the basepaths (7 SB).

## 3. News & Trends

• The Vargas Factor: Arizona’s Ildemaro Vargas is currently on a 25-game hitting streak. While impressive, the pressure of maintaining such a streak often leads to high-stress at-bats against elite power pitchers like Woodruff.

• Rest Advantage: Both bullpens are relatively fresh, but Milwaukee’s Trevor Megill has been more reliable in high-leverage situations (4 SV, 0.00 ERA in April) compared to Arizona’s middle relief.

• Venue: American Family Field is a “neutral” hitters’ park, but with the roof likely closed today, the air density favors Woodruff’s high-velocity fastball over Soroka’s sinker-heavy approach.

## 4. Final Pick & Prediction

While Michael Soroka is the “hotter” pitcher on paper, the Pythagorean analysis indicates that the Diamondbacks are playing above their weight class, while the Brewers are statistically stronger than their 15-14 record suggests. The loss of Moreno and Santana in the Arizona lineup makes it difficult to string together runs against a veteran like Woodruff.

• Over/Under Pick: Over 7.5 (-105) (Two elite starters in a rubber match)

• Projected Final Score: Milwaukee Brewers 4, Arizona Diamondbacks 3

Expert Note: Soroka’s 4-0 record is making the Diamondbacks an enticing underdog at +105, but Milwaukee’s home dominance and superior expected win percentage make them the safer analytical play.
