Timeform US SmartPlays: Wednesday 28 February

• Three best bets in the US from Timeform

#4 Z's So Good - Parx Racing, R2 (17:32)

Z'S SO GOOD is taken to step up on recent run and should give it a good go in trying to gain a second success. Gamerun gets class relief and is a contender as well. Shadow Box is also an interesting runner and can see out the three.

#5 Awesome First - Gulfstream Park, R1 (18:10)

AWESOME FIRST has gone close twice already and can finally earn his diploma on first start for new barn. Last Shift should give it a good go, while Assertive Attitude can make his presence felt back on dirt.

#1 Sheer Delight - Tampa Bay Downs, R5 (19:30)

SHEER DELIGHT has leading claims for the hat-trick on first start for his new trainer and seems likely to take the beating. Crowned Jewel faces a much easier task here than in last race and should also go close, while Deep Strike also requires consideration.
