Okay, so I got really into this whole “predicting tennis matches” thing, and I decided to focus on Stefanos Tsitsipas. Here’s how my little experiment went down.

First, I needed, like, a ton of data. I started digging through the internet, to find anything and everything I could get my hands on about Tsitsipas’s past matches.
Gathering Data
It was a bit of a mess, I started, you know, just grabbing stuff:
- Match results: Wins, losses, the whole deal.
- Opponent info: Who he played against, their rankings, their playing styles…it got complicated fast.
- Court surface: Because, duh, grass is totally different from clay.
- Tournament details: Big slams versus smaller events, was there pressure?.
Cleaning things up
Then came the boring part – cleaning up the data. It was all over the place! Different formats, missing info, typos…you name it. I spent hours just making sure everything was consistent and usable. and, made it all neat and tidy.
Trying some Prediction ideas
After I massaged the data I had something I could work with. I’m no stats whiz, so I kept things pretty simple at first. I started by calculating basic win percentages, head-to-head records against different opponents, and performance on different court types.
Finding Patterns
And wouldn’t you know it, the numbers did show that he’s way stronger on clay than on, like, hard courts.I compared his performance in big tournaments versus smaller ones. You could see some patterns starting to emerge.

Still Working on it!
Now, I’m not claiming I can predict every Tsitsipas match with, like, 100% accuracy. It’s all very much a work in progress. But it’s been a super interesting deep dive into how you can use data to make, you know, slightly educated guesses.
I’m still tweaking my methods and exploring new data points. It’s kind of addictive, actually!
