Max Verstappen extended his recent momentum by securing pole position for Saturday's Sprint at the Singapore Grand Prix, yet his session was overshadowed by a formal investigation into an overtaking manoeuvre involving Lewis Hamilton under yellow-flag conditions.
The Red Bull driver needed only a single flying lap in the closing stages of SQ3 to edge out Mercedes' George Russell by just over a tenth of a second. This latest pole comes on the back of Verstappen's breakthrough maiden pole for Red Bull last week in Malaysia, where he also went on to secure the team's first race victory of the season.
However, the stewards have opened an inquiry into an incident during SQ1 when Verstappen overtook Hamilton as yellow flags were being waved following debris on the circuit caused by Cadillac's Sergio Perez striking the barriers. Although Verstappen indicated over the radio that he had allowed the Ferrari driver back through, passing under yellow-flag conditions remains prohibited under the regulations.
The FIA confirmed Verstappen was under investigation after the session, with a potential penalty that could affect his Sprint starting position, though no decision has yet been reported.
Championship leader Kimi Antonelli struggled in the other Mercedes, qualifying only seventh. The gap between the two Mercedes cars highlighted the ongoing difficulties with the new specification introduced last week in Malaysia. Russell, who will incur a grid penalty for Sunday's main Grand Prix, is running the older specification and qualified half a second clear of Antonelli's newer-specification machine.
Ferrari appeared well-positioned heading into the final qualifying segment, with Charles Leclerc holding provisional pole after his opening lap. However, the Monegasque was shuffled back to third place by the session's conclusion.
Hamilton, who had also looked capable of challenging for the top spot, ultimately finished sixth. The McLaren pairing of Oscar Piastri and Lando Norris occupied fourth and fifth respectively, continuing their team's strong form through the weekend.
A timing system malfunction delayed the start of SQ2, as some final lap times from SQ1 had not been initially registered. Once the definitive final order was confirmed, qualifying resumed without further interruption.
