Okay, so lemme tell you ’bout this lil’ project I tackled: “tie break us open.” Sounds fancy, right? It ain’t. It was all about figuring out the probability of a tiebreak happening in a US Open tennis match. I mean, who doesn’t love a good tiebreak?

First thing I did was grab a bunch of data. I’m talkin’ years and years of US Open match results. I needed to know how many matches went to tiebreaks, you know, the actual numbers. Spent a good chunk of time just scraping websites and cleaning up the data. Trust me, data cleaning is the most unglamorous part of any project, but gotta do it.
Then, I started crunching those numbers. I wanted to see how often a tiebreak occurred in a set. It was pretty straightforward – just divided the number of sets with tiebreaks by the total number of sets played. I did this separately for men’s and women’s matches, ’cause, you know, they play different formats.
Here’s where it got a little more interesting. I wanted to estimate the probability of a tiebreak occurring in a match. This isn’t as simple as just looking at individual sets. You gotta consider how many sets are played in a match. For men, it’s best-of-five, and for women, it’s best-of-three. So, I had to whip out some basic probability calculations.
Basically, I calculated the probability of not having a tiebreak in any of the sets in a match. Then, I subtracted that from 1 to get the probability of having at least one tiebreak. Think of it like this: the chance of not flipping heads three times in a row, vs. the chance of flipping at least one heads.
- Men’s Matches: Calculated the probability of no tiebreaks in five sets, then subtracted from 1.
- Women’s Matches: Did the same thing, but for three sets.
I messed around with the data, sliced and diced it by year to see if there were any trends. Did tiebreaks become more common over time? Were there certain players who were more likely to be involved in tiebreaks? It was all about exploring the data to see what I could find.
The final step was kinda just putting it all together and seeing if the numbers made any sense. I compared my results to some other stuff I found online, just to make sure I wasn’t totally off my rocker. Turns out, my estimates were pretty reasonable.
It was a fun little project. Nothing groundbreaking, but it was a good excuse to mess around with some data and brush up on my probability skills. Plus, next time I’m watching a US Open match, I can impress my friends with my tiebreak probability knowledge. You know, be that guy.
