Juan Sebastian Molano sprinted to the Stage 12 victory in the 2023 Vuelta a España on Thursday, while Sepp Kuss kept the red jersey.

Molano, a Colombian, lost to Kaden Groves in the burst to the line at the end of Stage 4, but this time, he was too fast for the Australian at the end of the flat 151 kilometers from Olvega to Zaragoza.

Led out by his UAE Team Emirates colleagues, Molano took the stage victory ahead of Alpecin-Deceuninck's Groves, who had earlier won the intermediate sprint to tighten his grip on the green jersey.

Jumbo-Visma rider Kuss stayed 26 seconds ahead of Spaniard Marc Soler and 1 minute, 9 seconds in front of reigning champion Remco Evenepoel in the general classification battle.

Three-time Vuelta winner Primoz Roglic, fourth, gained four seconds by finishing second in the intermediate sprint.

"Thanks to my team -- they were amazing today," Molano said. "I'm very happy to win a stage in the Vuelta last year, now this year."

The Colombian was hit by a car while training in Belgium in March, leaving him concussed and with a broken toe.

"After the incident, (it was) not easy to return, but now it's OK, and I'm very happy," he added.

Emirates rider Rui Oliveira launched Molano to victory in the finale, with Boy van Poppel third behind Groves.

"In the end, we got bumped by UAE, who came with momentum," Groves, who won Stage 4 and Stage 5, told Eurosport. "And my chain actually dropped, so... I managed to get it on, and I think I showed a really strong sprint, but unfortunately it was too far back, too late. I'm super disappointed because it could have been win No. 3."

Stage 13 on Friday is a key one for general classification contenders, featuring over 4,000 meters of climbing in the Pyrenees on a 135-kilometer run from Formigal to the Col du Tourmalet in France.

This is the 78th edition of the Vuelta, which ends in Madrid on Sept. 17 after 21 stages and 3,153.8 kilometers.
