Adri Arnaus and Guido Migliozzi fired the lowest rounds of their European Tour careers to share the lead heading into the final round of the Magical Kenya Open presented by Absa.
The playing partners put on a stunning show on day three at Karen Country Club, as Arnaus took the lead at the turn before Migliozzi surged past him on the back nine to lead by two.
A two shot swing on the last left then the duo tied at the top at 14 under, with the Italian carding a 64 and Spaniard Arnaus taking one more shot.
Overnight leader Louis de Jager was at 13 under after a 70, a shot clear of India's Gaganjeet Bhullar and Finn Kalle Samooja.
Qualifying School graduate Migliozzi arrived in Nairobi having made just seven cuts from 37 starts across the European Tour and European Challenge Tour since 2013 but looked like a seasoned veteran in the penultimate group.
“I played very solid out there today," he said. "My putting was really good, I have been working at that a lot on the greens over the past few days and I saw a lot of good results from that today.
“I am confident with my game and I am hoping that my best game, like I played today, will be enough tomorrow.”
Arnaus has enjoyed a more productive start to his European Tour career after graduating off the Challenge Tour last season, and arrives in good form after a top 15 at last week's Commercial Bank Qatar Masters.
“I have been in this position before and I think that everything in the past is going to help me," he said. "All I have to do is try and play good golf again tomorrow. It has been a lot of fun so far and hopefully it will continue to be."
De Jager entered the day with a four shot lead but bogeyed the first and while he bounced back on the fifth from just off the green, he had to play out of a bush with the back of his club on the next for a second bogey of the day.
That allowed Arnaus to join him in top spot as the 24-year-old put his tee shot to four feet on the par three fourth, holed a long putt on the fifth and took advantage of the par five sixth.
He then drove just through the back of the par four seventh and two putts handed him the lead on his own.
De Jager hit back with an approach to five feet at the eighth but a 12 footer at the ninth from Arnaus edged him back ahead at the turn.
Migliozzi turned in 31 as he put his tee shot to eight feet at the second and sandwiched a birdie at the sixth with excellent approaches to the fifth and seventh but he was still two shots off the lead.
De Jager made a birdie from five feet at the tenth and both the leaders took advantage of the 11th but so did Migliozzi and he then found another gear.
The 22-year-old holed from eight feet at the par five next and when he made a 15 foot putt on the 13th, there was a three way tie for the lead.
De Jager had to play out of a bush with the back of his club again on the 13th and while he picked the shot back up from 12 feet on the next, back to back bogeys from the 15th sent him backwards.
Arnaus also bogeyed the 15th and when Migliozzi got up and down from the front of the 17th, holing an 18 footer, the lead was two.
The leader then made his first error of the day on the last and Arnaus rolled a brilliant fast putt down the hill for a closing birdie and a share of the lead.
Coming up behind in the final group, De Jager hit a stunning approach into the 18th, spinning the ball to a standstill and rolling home a closing birdie.
Bhullar had shared the lead with birdies on the first, second, fifth and sixth but dropped a shot on the next before bouncing back with gains on the 11th and 13th - courtesy of a chip-in. He then took advantage of the short 17th but dropped a shot on the last.
Challenge Tour graduate Samooja looked out of it as he turned in 34 with three birdies and two bogeys but he came roaring home in 30, birdieing the tenth, 13th, 15th and 17th, and eagling the 12th in his lowest European Tour round.
South African Justin Harding, Scot Liam Johnston and England's Jack Singh Brar were at ten under, two shots clear of South Africa's George Coetzee and Northern Irishman Cormac Sharvin.
