What No. (number) did Tony wear with the Cardinals? I know in the baseball card ep he said his No. was 24. But another one at the Cardinals reunion he wore No. 35. In the softball ep his t-shirt didn't have a No. haha. Did we ever get an official answer? Kinda want to do a custom jersey or t-shirt.

The writers were inconsistent.

Sam says, "I got your number, 42". Tony replies, "My number was 24". Sam says she will wear the jersey inside out. I assumed this was maybe a high school basketball number not his MLB number.

It's not uncommon for a player to switch numbers. A famous example, Michael Jordan wore both 23 and 45 in career (even wore 12 in one game, but we won't go into that)
