FRIENDS PROVIDENT t20, New Road:
Worcestershire 208-7 (20 ovs) beat Yorkshire 187-7 (20 ovs) by 21 runs
Smith broke into Australia's limited-overs team this winter
Yorkshire went down to their second FP t20 defeat in two nights with a 21-run defeat by Worcestershire at New Road.
James Cameron (51) top-scored in the hosts' 208-7, with debutant Steve Smith making 34 and openers Vikram Solanki and Phil Jaques contributing 30 each.
Gareth Andrew then picked up two wickets as the visitors slumped to 75-5 in reply.
Anthony McGrath (39) and Adil Rashid (34) tried to repair the damage, but Yorkshire fell short on 187-7.
Worcestershire got off to an impressive start, with Solanki and Jaques taking 18 off the first over, bowled by spinner Azeem Rafiq.
Solanki was the first to fall, caught at mid-on by McGrath off Steven Patterson before Jaques was bowled going for a big hit in Rich Pyrah's first over.
McGrath then held a one-handed catch on the boundary to dismiss Alexei Kervezee off Rashid, while Moeen Ali had his middle stump knocked back by Rafiq to leave Worcestershire 101-4 at the halfway stage.
Daryl Mitchell then fell cheaply to Rashid before Cameron, who hit four fours and three sixes, and Smith, with three maximums of his own, combined for a sixth-wicket stand of 58 that propelled Worcestershire to what proved to be a winning score.
The Yorkshire top order then crumbled at the hands of seamers Andrew, Imran Arif and Jack Shantry.
Smith picked up his first Worcestershire wicket when Gerard Brophy was caught by Kervezee and, despite the efforts of McGrath and Rashid, the Tykes never recovered.
