Khawaja moves on from 'horrendous' drops

"Sometimes you just have horrendous games".

Usman Khawaja had a simple explanation for his two howlers in the field during Australia's ODI loss to the West Indies in St Kitts earlier this week.

Khawaja scored 98 but failed to hold chances provided by both openers Johnson Charles and Andre Fletcher, who shared a 74-run stand to take the game away from Australia.

"I don't think we fielded particularly well and obviously I put my hand up in that department," Khawaja said in Barbados.

"I'm not the first person to drop a catch. It happens. You try and move on as quickly as possible.

"Sometimes you just have horrendous games, you just can't do anything about it."

The left-hander wasn't alone in committing fielding errors during the contest, with skipper Steve Smith lamenting a "sloppy" performance from his side.

The issue cropped up during the recent summer, when skipper Ian Chappell described Smith's team as "the worst Australian fielding side since the mid 80s".

Fielding was the sole focus of the team's first training session at Kensington Oval today.

The squad didn't bat or bowl at all, with stand-in coach Justin Langer instead working them over in a series of intense drills.

"Obviously it's a big part of cricket. A big part of what we do well. If we're fielding well, we usually win games so it's quite important," Khawaja said.

"It was just a little blow out. We had two days off so we just had a fielding session this morning, so we could put all our energy into that.

"It was pretty tough work. It gets pretty hot out here, it's quite humid."

Smith did not train, resting a sore quad, but is not considered to be in any doubt for the clash with South Africa that starts at 3am AEST on Monday.

Team management described it as a precautionary move, with the gifted batsman expected to train later this week.

Australia's last-start loss, coupled with the Proteas' recent pounding of West Indies, leaves the ongoing tri-series in the balance.

All three sides are in the mix for the June 26 final, having banked two wins from four matches.

"We've got two games then hopefully a final," Khawaja said.

"You just want to get into the final, it doesn't matter how you get there.

"We're still playing some really good cricket. We showed glimpses of it, but ... we want to be consistent."
