Two Blood-Horse staffers covering Saturday's event at Arlington Park agreed to offer their selections in a head2head battle of their own.Dan Liebman and Evan Hammonds, who have been on the scene in Chicago this week, were each given a $1,000 mythical bankroll. The only rule is $100 must be wagered on each race. The remaining $200 may be bet on any race or races. These selections were made Friday morning.Check out the action here.
