MLB slogans time! There are hardly any new slogans as of today. I will update this list as teams add or change slogans. The ones with the asterisks are the new ones. Every year I look forward to the Mariners' slogan, but they've lost a little off their heater with "Believe Big." The Marlins are leading so far in 2010, creativity-wise. For last year's slogans, click here.
