KNOCK KNOCK JOKE (7) finished in the money last time out over 1m1f in stakes class at Sunland Park (Dirt), beaten 4 lengths. Rates strongly in this and can break through here. ZORRO D' ORO (2) is building towards a maiden win after minor placings at his last two runs, the latest when second over 6f at Sam Houston Park (Dirt), beaten 2 lengths. Should be poised just off the lead. Will play a major role. EIGHT SEVEN MAGIC (1) stuck on well last start to finish third over 6f at Sam Houston Park (Dirt) after showing good early speed. Placed to advantage and can take this out. C'MON CHAOS (5) ended up 7 lengths behind the winner in eighth on debut last start over 6f at Sam Houston Park (Dirt). Will take a lot from that experience. Don't underestimate.
