MERCKX (2) was fourth on debut then ran a better race to finish third last time, beaten 4 lengths over 1673m at Woodbine All Weather. Expected to be very competitive again with the introduction of Lasix. TRUE NORTH STAR (11) is on debut for the Mark E Casse stable. Two-year-old colt by Early Voting from She's Got Moves. Bold showing expected. Watch betting. GHOSTFACE (7) was well in the market on debut last start but could only manage fifth at this track over 1308m. Can sneak into the finish. JACK SPARROW (1) finished ninth two runs back then improved last start but found a couple better over 1308m at this track, beaten 5 lengths. Likely improver with strong prospects.
