MARINAS CALGARY (1) comes off a moderate effort last start, finishing fifth at this track over 450m behind Slippy Dottie (28.28). Has ability and looks hard to stop. DO NOT DISTURB (6) is mixing his form in handicaps. Nice win two runs back at this track then when starting off scratch finished fifth, beaten 2.25 lengths, at this track over 450m (28.23). Takes on another handicap here and breaks from the back. Better than the last run and is not to be underestimated. SWIFT ERASURE (5) well back settling but did wind up strongly to finish 5th and beaten only 4.5 lengths (28.32) at this track. Can do much better this time. GO ON LAINEY (2) is a last-start placegetter with solid claims again.
