Antonio Guerao Mayoral (born 28 April 1979), known as Tonet, is a Spanish retired footballer. Mainly a left midfielder, he could also operate as a central defender or a left back.
Born in Barcelona, Catalonia, Tonet was an unsuccessful FC Barcelona youth graduate. He played professionally for Deportivo Alavés B, CF Gavà, Real Oviedo B, Real Ávila CF, SD Compostela, CF Reus Deportiu, CF Rayo Majadahonda, CF Fuenlabrada, AD Alcorcón and CE L'Hospitalet.
In a full decade, Tonet never appeared in higher than Segunda División B.
On 4 August 2008 Tonet moved to the Scottish Premier League, signing a one-year contract with St. Mirren after impressing on trial in pre-season, which included a goal against Football League Championship's Blackpool.
His league debut came against Celtic in a 0–1 away defeat, and he went on to play in the first four games, being sent off against Heart of Midlothian in another loss. However, after suffering a foot injury from which he never fully recovered, he was deemed surplus to requirements early in the following year, and released by manager Gus MacPherson at the season's end.
