FP1 Results Overview
The team's Spanish veteran was fastest in front of Ferrari's Charles Leclerc and Dutch ace in FP1 for the Marina Bay race.
McLaren's title rivals Australian rookie and Lando Norris finished the session in mid-table positions.
Piastri was over two tenths quicker than his teammate.
Alonso was a slim margin ahead of the Ferrari driver and a clear gap faster than the Red Bull star.
The Italian squad's seven-time champion was just outside the top three.
Car Performance
Unlikely that the Silverstone-based team will be contenders for the top spot.
However, the team are hopeful of a better weekend on a low-speed track that is ideally suited to their chassis, which excels when significant amounts of downforce are called for.
Veteran racer Fernando is also renowned as a Marina Bay expert, and often shines on the Marina Bay street track.
However he was likely using reduced weight or a increased power than his competitors, or each, to post the fastest lap.
Session Details
His team-mate Lance Stroll was 1.918secs slower in the lower order.
He had difficulties with his cockpit during the initial runs and was also testing new components.
FP1 in Marina Bay is not representative of race pace for qualifying and race as it is run in daylight in late afternoon, while qualifying and the main event are held under floodlights.
Championship Standings
The McLaren driver is ahead of his teammate by a solid margin with seven races left heading into the event in the Lion City.
The Woking-based team are poised to secure the constructors' championship on the weekend.
Sole scenario they can fail to secure it in this race is if the Silver Arrows beat them by 31 points or Ferrari manage it by 35.
Competitor Outlook
Red Bull are positive of a strong result after recent successes in Italy and Azerbaijan ahead of this weekend.
It was a relief when precipitation coming down before the session cleared by the point the machines went out on a circuit that had remained dry.
Team consultant the Austrian said ahead of practice that they required a uninterrupted running to begin properly on optimizing their set-up for the event.
