Alex will have to change his recent running style to win the Belmont, that burst of speed he had worked at the Preakness, but going a mile and a half is a different story. I think a little early to have an opinion though, without seeing who else gets entered.
Alex used to lay closer to the pace, he does have some speed if they want to use it, but in the Derby and Preakness they were so many front runners, he could afford to lay back and let them knock each other out.
