Baltimore is the team I am most surprised with considering the teams they have beaten. now for teams I think will sustain their early season success are Florida and Seattle.
Have pretty big futures on both. IMO Florida has the best, and deepest staff in the league. 1-5 they are better then everyone. Plus Hanley is only hitting .235. One of the best players in baseball hasn't even began to play like he is capable and they are still 11-1. New York, and Philadelphia better not let this team get too far out or they will run and hide.
I also think Seattle is the team to beat out west. With Anahiem's injury problems to both their pitching staff, and best hitter (vlad) the Mariners need to pad their lead before they all get healthy around mid May, early June. With Felix, and Bedard heading their staff, and Morrow in the back of their pen this team can easily win the West if they get any resemblance of run support.
