Australia's baseball team looks set to have to negotiate a tricky two-stage qualification process to make the Tokyo Olympics after successive losses at the Premier12 baseball tournament.
After host nation Japan came from behind on Monday to beat them 3-2, the Australians suffered a 3-0 shutout on Tuesday against unbeaten Mexico.
Australia are now bottom in the super round standings, with games against the United States and Taiwan to come ahead of the weekend's medal clashes.
They effectively need to finish higher than South Korea and Taiwan to qualify directly for Tokyo.
Otherwise, they will have to win an Oceania qualifier early next year to qualify for a six-team international tournament in Taiwan, where the winner will earn the last Olympic berth.
Mexican centre fielder Jonathan Jones homered off the first pitch in their opening inning.
Mexico then score two more runs in the fourth as Australia stranded four runners on base.
On Monday, Australia had led through six innings before Japan came back to win.
Australia had banked just one win in their opening-round series of matches but that had proved enough to progress to the super-round stage as they finished above Canada and Cuba for second spot in Group C.
