Smith sizzles in 200m backstroke, Weinstein shocks Ledecky in 200 freestyle

LOS ANGELES: Regan Smith, shaping up for a World Championships showdown with Australian Kaylee McKeown, clocked a blistering 2min 03.80sec to win the 200m backstroke at the US swimming championships on Wednesday.

Smith, whose previous world record was broken by McKeown in March with a time of 2:03.14, showed again that her move to train with coach Bob Bowman — former mentor of Michael Phelps — — was paying off.

“I haven’t been 2:03 in four years, and I’m just so happy to be back where I was,” a beaming Smith said after posting the fifth-fastest time ever and beating Rhyan White by 1.97sec.

Smith, who also won the 200m butterfly on Tuesday, set up a tantalizing test with McKeown at next month’s World Championships in Fukuoka, Japan.

Since breaking’ Smith’s world mark in March, McKeown has gone on to clock an impressive 2:03.70 at the Australian trials this month.

Elsewhere, 16-year-old Claire Weinstein ran down freestyle great Katie Ledecky to win the 200m free.

Weinstein was second at the 150m mark and overhauled Ledecky over the final 50m to win in 1min 55.26 sec — two-hundredths of a second in front of the seven-time Olympic gold medallist.

“It feels amazing,” Weinstein beamed after securing her trip to Fukuoka, Japan, next month.

She had made the team for last year’s worlds in Budapest with a runner-up finish to Ledecky in the 200m free at trials. She earned a 4x200m free relay gold but was eliminated in the semifinals and she’s looking to improve on that this time.

Ledecky had already shown she remains a force to be reckoned with on Tuesday, winning the 800m freestyle in a 8:07.07 — her fastest time since she set the world record of 8:04.79 at the Rio Olympics in 2016.

Ledecky won 200m free gold in Rio but
