Okay, here’s my take on sharing my experience with building MLB Opening Day rosters, blog-style:

Alright folks, so I finally tackled something I’ve been meaning to get around to for ages: creating MLB Opening Day rosters. It was a bit of a grind, but totally worth it. Let me walk you through it.
First off, I knew I needed data. Obvious, right? I started by hitting up the official MLB site. Figured they’d have the most accurate info. I spent a good chunk of time just browsing, clicking around, trying to figure out where they stash those opening day rosters. It was a bit of a treasure hunt, not gonna lie.
Eventually, I found some team pages with current rosters, but nothing specifically labeled “Opening Day.” Bummer. So, I switched gears and started digging through news articles and sports websites. ESPN, Bleacher Report, all the usual suspects. It was a lot of copy-pasting into a spreadsheet at this point. Super manual, super tedious. My eyes were starting to cross.
After a few hours of that, I realized I needed a better strategy. Web scraping, anyone? I’d dabbled in it before, so I figured I could whip something up to automate the process. I used Python with Beautiful Soup and Requests. Man, those libraries are lifesavers. I targeted a few sports news sites that seemed to have reliable historical roster data. It took a while to get the selectors right, but once I did, it started pulling data like a champ.
The data I got was messy. Player names, positions, sometimes even batting orders, all jumbled together in different formats. Time for some cleaning! I used Pandas to massage the data into something usable. Lots of string manipulation, renaming columns, and dealing with missing values. It wasn’t pretty, but I got it done.

Next up was figuring out how to actually represent the rosters. I wanted something clean and easy to read. I decided to go with a simple table format, with columns for player name, position, and a few key stats (like batting average, ERA, etc.). I thought about adding more advanced stats, but I wanted to keep it relatively simple.
I built the tables using HTML and CSS. I played around with different layouts and color schemes until I found something I liked. It’s not the prettiest thing in the world, but it gets the job done. I then made it so each team has their own individual page.
Biggest Challenge? Definitely wrangling the data. Getting it from various sources and cleaning it up was a real pain. Also, dealing with injuries and last-minute roster changes. You know how baseball is. Guys get hurt, traded, sent down to the minors… it never ends!
What I Learned? Web scraping is powerful, but data cleaning is where the real work is. Also, patience is key. This project took way longer than I expected, but I’m glad I stuck with it.
Now, I’ve got a pretty solid set of MLB Opening Day rosters. I’m thinking about adding more features in the future, like historical data or player comparisons. But for now, I’m just happy to have it done.

- Gathered data from MLB site and sports news websites.
- Used Python, Beautiful Soup, and Requests for web scraping.
- Cleaned and transformed data using Pandas.
- Created rosters table using HTML and CSS.
Would I do it again? Absolutely. It was a fun and challenging project. And now I have a cool dataset to play around with. Plus, I learned a ton along the way.
That’s about it, folks. Hope you found this helpful! Let me know if you have any questions.
