Perkins and Temple medal as Walsh reigns at worlds

Alex Perkins and Matt Temple have grabbed bronze medals for Australia on a record-shattering day again dominated by US sensation Gretchen Walsh at the world short course swimming championships in Budapest.

Perkins took bronze in the women's 100m butterfly final on Saturday, while Temple also finished third in the equivalent men's event.

But even freakishly brilliant Canadian teen Summer McIntosh, who obliterated the 400m individual medley mark, had to swim in the shadow of 21-year-old Walsh, who took her tally of world individual records over the week to an unthinkable eight.

In the greatest week's work witnessed at a short course meet, the Nashville swimmer created two more individual landmarks on Saturday as she lifted her fifth gold of the week in the 100m fly.

While Walsh won in 52.71 seconds to take 0.16s off the mark she'd set the night before, Queenslander Perkins forged on way behind in what felt almost like another race even though her 55.10 was in itself an Oceania record, to finish third behind Dutchwoman Tessa Giele (54.66).

Not satisfied, Walsh returned 50 minutes later to the Duna Arena 25-metre pool in the semi-finals of the 50m freestyle, clocking 22.87s to take 0.06 off the world record set by Dutchwoman Ranomi Kromowidjojo seven years ago.

"I was definitely a little bit shocked, it was quite a short turnaround, but everything's going my way," beamed the American, who's broken nine world records over the week, including one in a relay, and could make it 10 in Sunday's last-day final of the freestyle dash.

"It's been harder and harder to get through these races, just because it's been a really long meet. To break the butterfly record, it's something amazing, it's crazy, and yeah, I'm really happy with it."

Perkins felt it a privilege to have been racing against Walsh.

"I been really proud of how I have gone about things … and to compete against the likes of Gretchen Walsh," the 24-year-old said.

"Gretchen's an incredible athlete. I don't think anyone's going to come close to her for a while to come, so it's really amazing to see her backing up for two world records like that."

Kromowidjojo was on hand to present Walsh with her eighth world-record bonus cheque of $US25,000 ($A39,000) for the week, giving her an individual total of $US200,000 ($A312,000).

The 25-year-old Victorian Temple also played his part in a record-breaking affair as he came home third in 48.71s behind Frenchman Maxime Grousset (48.57) and Swiss Noe Ponti, who broke Caeleb Dressel's 100m fly record in 47.71.

"A medal winner at the World Championships, you can't beat that," smiled Temple. "Coming off the Olympic Games, it's always a hard one trying to get back in the water, and to be 0.1 off my best I can't complain."

The 18-year-old McIntosh racked up the 24th world record of the meeting -- an all-time record for the championships -- as she clocked 4:15.48 to slice three-and-a-half seconds off the seven-year-old record of Spaniard Mireia Belmonte (4:18.94).

In the men's 50m free, Jordan Crooks, from the Cayman Islands, became the first man ever to break the 20-seconds mark in his semi-final, clocking 19.90s to eclipse the mark of 20.08 he had set in the heats earlier in the day.

The mixed 4x100m medley relay team of Iona Anderson, Josh Yong, Temple and Milla Jansen just missed out on Australia's 12th medal of the championships, as they finished fourth in 3:32.83 behind a victorious Russian quartet competing under a 'neutral team' flag.
