Alright, let’s talk about my little adventure with predicting Ruud Cerundolo’s matches. It all started because I was bored one weekend and wanted to try my hand at something new – something beyond just passively watching tennis.

First, I grabbed a whole bunch of data. I’m talking about match results, player stats (like serve percentages, break points saved, etc.), court surfaces, weather conditions – you name it. I scraped it from various tennis websites, and let me tell you, data cleaning was a PAIN. So much inconsistent formatting! I almost gave up right there.
Then, I decided I needed some kind of system. Just looking at the data wasn’t going to cut it. I started simple, just trying to figure out which stats seemed to correlate with wins for Cerundolo. Forehand winners? First serve percentage? Opponent’s unforced errors? I threw it all into a spreadsheet and started crunching numbers.
Next up was trying to build a little “model”. I use that word loosely, because it was really just a bunch of weighted averages. I gave certain stats more “weight” based on how well they seemed to predict past results. This was a lot of trial and error. I kept tweaking the weights, running the model on old matches, and seeing how often it was right. It was way off at first, but I slowly got it dialed in to something that was… kinda okay.
Of course, the real test was trying to predict actual matches. I picked a few of Cerundolo’s upcoming matches and fed all the available data into my “model.” It spat out its predictions, and then I just had to wait and see what happened. Talk about nerve-wracking!
The results? Well, let’s just say I’m not quitting my day job. I got some right, I got some wrong. It was definitely a mixed bag. But it was also super interesting. I learned a lot about what goes into tennis analysis and how difficult it is to predict these things. There are so many factors that the data can’t capture – things like player momentum, mental game, even just plain luck.

Ultimately, it was a fun experiment. I definitely gained a new appreciation for the complexity of tennis prediction. And who knows, maybe I’ll keep tweaking my model and eventually become a world-renowned tennis oracle. Okay, probably not. But it was a good way to spend a weekend!
What I Learned
- Data cleaning is the worst part of any data project. Seriously.
- Building even a simple prediction model takes a lot of time and effort.
- Tennis prediction is HARD.
- Even a bad model can be surprisingly insightful.
So, that’s my Ruud Cerundolo prediction saga. It was a fun ride, and I might even try it again with another player sometime. Wish me luck!
