Tosti had a successful amateur career and was low amateur at the 2012 Open de Argentina with a score of 69-73-69-70. He was runner-up at the 2013 South American Junior Championship, and the 2015 Latin America Amateur Championship with a score of 69-70-68-71.[2]
Tosti turned professional after graduating in 2018 and joined the PGA Tour Latinoamérica. In 2019, he won his first title, and in 2022 he won a second title and finished 5th in the Order of Merit, to earn graduation to the Korn Ferry Tour.[5]
He gained media attention after accepting a shuttle ride, believing it was an official courtesy car, from the 18th green to the first tee mid-round at the LECOM Suncoast Classic, receiving a two-shot penalty for breaking an obscure model local rule that says players may not use transportation during a round.[6]
In August 2023, Tosti claimed his first win on the Korn Ferry Tour at the Pinnacle Bank Championship, also claiming a card for the 2024 PGA Tour season.[7] Two weeks later, he was forced to withdraw from the Albertsons Boise Open following an undisclosed disciplinary matter.[8]
