Steve Smith stood unbeaten on 104 after crossing 10,000 Test runs and helped Australia pummel Sri Lanka alongside fellow centurion Usman Khawaja on Day One of the opening Test on Wednesday. 

Australia reached 330-2 in 81.1 overs when rain stopped play for the day after the tourists elected to bat first in Galle at the start of the two-match series. 
Left-handed opener Khawaja (147*) and skipper Smith put on an unbeaten stand of 195 to thwart the opposition attack in two wicketless afternoon sessions.
