The 25-year-old German called for help on social media after winning the women’s long jump T20/37/38/42 with a leap of 4.65 metres - 14 centimetres shy of the world record mark she set on the way to winning gold at the 2015 IPC Athletics World Championships in Qatar’s capital Doha.

"My running legs got stolen today. Please help me find/replace them!," tweeted Low, who opened her season with three jumps over the 4.60m mark.

The United States’ Lacey Henderson came second with a jump of 3.48m, followed by compatriot Scout Bassett in third with 3.16m.

Elsewhere on the second and final day of competition, the US's David Blair smashed the discus F44 world record with his phenomenal throw of 63.61m adding 15cm on to the mark set by fellow American Jeremy Campbell on home soil four years ago. 

Campbell, the reigning Paralympic and world champion, had to settle for second place today with a throw of 57.53m.

Blair, 40, finished second behind Campbell at last year’s IPC Athletics World Championships with what was then a personal best of 60.46m.  

Another American showing promising form already this season is Parapan American champion Jarryd Wallace.

The 25-year-old sprinter took the win in the men’s 100m T44 in 10.78sec, as his compatriot Trenten Merrill finished in second place in 11.78.

World champion David Brown, also of America, continued his winning ways out on the track, clocking 11.04 in the men’s 100m T11 to add to his victory over 200m yesterday.

US sprinter Kym Crosby secured her hat-trick of wins in Arizona, clocking 12.52 in the women’s 100m T11/12/13 before following that up later in the day with 59.70 to win the 400m T11/12/13.

Ghana’s Maclean Dzidzienyo also completed a Grand Prix sprint treble thanks to wins today in the men’s 100m T53 and 400m T53 with times of 16.26 and 54.78 respectively.

Talented 15-year-old Alexa Halko of the US took the tape in the 100m and 400m, winning the 100m T33/34/51/52 in 18.63, and then clocking 1:04.03 to win over one lap.

Canada’s Virginia McLachlan added to her 200m win from yesterday with victory in the 100m T35/36, clocking 16.66.

Trinidad and Tobago’s Nyoshia Cain did likewise in the women’s T42/43/44 with a time of 13.15.

Out in the field, the US's Scott Winkler added to his discus win from yesterday with victory in the shot put F54/55, throwing 10.14m.

His compatriot Michael Wishnia won the T56/57 throw with a best of 13.61m.

Denmark’s Daniel Jorgensen, winner over 100m in 12.65 earlier in the day, secured victory in the men’s long jump T42 with a leap of 6.48m - just five centimetres less than his world record mark set in Italian city Grosseto last year.

Japan’s Hajimu Ashida topped the podium in the men’s long jump T43/44/45/46 with a jump of 6.48m.
