Spanish striker Garcia, filling in for the injured Kylian Mbappe, opened the scoring after 20 minutes and then volleyed home a superb second early in the second half to give Madrid a commanding lead.
Raul Asencio further extended Xabi Alonso’s side’s advantage before Cucho Hernandez pulled one back for Manuel Pellegrini’s visitors, sixth.
Madrid youth academy product Garcia completed his hat-trick after 82 minutes with a clever flicked finish to delight fans at the Santiago Bernabeu, with Fran Garcia notching a late fifth.
Madrid, second, cut Barca’s lead back down to four points after the champions edged Espanyol 2-0 in a Catalan derby on Saturday.
Atletico Madrid, fourth, were held 1-1 at Real Sociedad later on.
Madrid’s victory eased the pressure on Alonso, who scraped through to 2026 at the helm despite reports he was on the verge of being sacked after a run of inconsistent form.
With top goalscorer Mbappe sidelined with a knee sprain, Alonso turned to 21-year-old forward Garcia to replace him, as he did during the Club World Cup last summer.
Garcia’s opportunities have been limited this season despite acquitting himself well in the United States and he proved himself again.
“These were three very special goals, my first hat-trick here at the Bernabeu, my first goals this season as well,” he told reporters, before admitting he still faces a fight for minutes.
“In front of me I obviously have the best players in the world, like Mbappe, Rodrygo (Goes), (Jude) Bellingham, Vinicius,” he continued.
“I just focus on myself, which means working day by day and taking the opportunities the coach gives me, like today, and I hope I can deliver and help my teammates every minute I get.” (AFP)
