The NPB announced their 2011 slogan today:
Be Prepared: Why are you here?
There's a pretty detailed explanation as to why this slogan was selected, but I don't really have the time to get into it right now. If you're interested, and can read Japanese, you can get the rundown at the official site.
102 rookies attended the 2011 Rookie Seminar that took place in Tokyo today -- 68 players from the 70-man rosters, 29 Ikusei players, and 5 NPB umps.
