QUEEN MCKINZIE (7) was beaten for early speed and didn't come into contention when a disappointing eighth over 1207m at Churchill Downs (Dirt) most recently. Will enjoy a drop in class so she is a major player. RUMBAR (3) was out of the money when resuming from a spell last start over 2414m at Churchill Downs Turf, beaten 23 lengths. Tackling a more suitable race so she is a key runner. SILVERTOWN (4) finished 8 lengths away in fifth last time out over 1408m at Churchill Downs six weeks ago. Steps up in distance today. Has good early toe so she should be handy in the run. Should be involved in the finish. LEXICO (6) returns after ten weeks in the paddock. Closed the last campaign with a ninth over 1710m at Churchill Downs Turf (Turf). Solid top-three hope.
