Modeling And Predicting Momentum In Tennis Games, Patrick Baldwin-Mccurdy, Alexander Habib, Abey Joseph

SUURJ: Seattle University Undergraduate Research Journal

As if being the first Wimbledon winner in over 20 years whose name wasn’t Djokovic, Federer, Murray, or Nadal wasn’t enough, Carlos Alcaraz’s victory was even more astonishing considering he came back after being handily dealt with by Djokovic in the first set of the final 1-6. Alcaraz’s miraculous recovery might be explained by a shift of flow in the game in his favor. In this paper, we compare two models that both interpret a small amount of past data within a given tennis match to determine which player has the current advantage, or “flow,” in the next game.
