Nick Livingston, Game Designer for MLB 13 The Show has posted another Developer Journal. This year the team has added more depth to Play Now online matches by incorporating some elements from other areas in the game.
We now have an intelligent way of measuring who is the best of the best on the Leaderboard. You don’t have to play tons of games to be at the top of the leaderboard, you just have to prove that you can hang with the better players. Even if that means a game or two a week, you will find your place on the leaderboard before long.

I don't play much online, but when I do, I mostly play with the Pirates and you know who my typical opponent would be (top team with the ace of the staff).
