The second practice session saw Leclerc, Oscar Piastri and Yuki Tsunoda set the top three fastest times respectively.
Can Tsunoda emulate this pace in qualifying?
Following an impressive result in free practice, Tsunoda remained confident about RB's chances for the rest of the weekend.
"So far I'm confident that I'm able to be in Q3 and top 10, yeah top 10 will be likely, but at the same time anything can happen, so we just need to stay sharp and especially in midfield. still it's very very tight,” he said to F1 TV.
“But obviously I'm aiming for the highest position as much as possible and at the same time focus to extract the maximum from the car."
Despite his success, the Japanese driver was involved in a strange incident during the practice session, resulting in an investigation from the stewards.
Tsunoda was allegedly in breach of Article 12.2.1 i) of the International Sporting Code due to an incorrect practice start on the exit of the pit lane at Imola.
The investigation resulted in a reprimand for Tsunoda, his first of the season, and the stewards will take no further action following the incident.
