Jason Smyth remains on course for double gold at the World Para Athletics Championships after he powered into the final of the men's 200m T13.
Smyth has already claimed gold in the 100m event after a hugely impressive run on Sunday night and he will be hoping to make it two from two in tomorrow evening's final.
The Derry man won his heat in a time of 21.89, which was good enough to set a new season's best time for him.
Smyth, who ran the fastest time of all the qualifiers for the final, will go in lane four in Tuesday's race which has a start time of 7:55pm.
"I got a good start and ran a strong bend to put my competitors under pressure. The plan worked well and I was in a postion then to just cruise home," he said.
Elsehwere, teenage sprinter Orla Comerford finished in sixth place in the women's 100m T13 final.
The Howth woman clocked a time of 12.58 second in an incredibly tight race in which .58 of a second was all that separated the top six runners.
Comerford's time was just .03 away from her personal best. Speaking afterwards the NCAD student said: "I was really delighted with my start. My plan is to continue to knock off fractions of a second yearly towards Tokyo. At 19-years-old I have years to hunt down these girls."
Ukraine's Leilia Adzhametova took the gold in a time of 12 seconds flat with silver going to South Africa's Ilsa Hayes and Kym Crosby of the USA grabbing bronze.
Earlier in the day Paul Keogan booked his place in the T37 200m final after finishing third in his heat.
Keogan clocked 25.27 seconds to progress and keep alive his mission to add to Ireland's haul of four medals at the Championships.
It would be a sweet redemption for the Meathman, who suffered the agony of a false start at the Rio Games last September.
Keogan's Paralympics ended before it had even started as he was disqualified from his T37 400m heat in heartbreaking fashion.
"I went before the gun," he told RTÉ Sport when reflecting on the disqualification.
"Technically that would be considered cheating. It’s quite sickening, but I don’t think unfair would be the right word to use."
He’s entered into the 200m and 400m events in London.
