Cristiano Ronaldo struck again in Real Madrid's 5-0 rout at Almeria before going off injured, while Barcelona didn't miss sidelined star Lionel Messi as it eased past 10-man Granada 4-0 to retain the Spanish league lead on Saturday.
Fresh from scoring four goals to lead Portugal past Sweden in their World Cup qualifying playoffs, Ronaldo extended his scoring run to eight straight games for club and country by grabbing Madrid's third-minute opener.
Ronaldo walked off the pitch in the 52nd with a suspected hamstring injury before Karim Benzema, Gareth Bale, Isco Alarcon and Alvaro Morata added goals.
"It was for precaution," Ronaldo said. "It's nothing special. I was kicked in the first half and had the muscle a little stiff."
Madrid coach Carlo Ancelotti said Ronaldo had "a problem with his hamstring" and he would undergo more tests on Sunday.
Messi-less Barca cruises
Andres Iniesta and Cesc Fabregas earned and converted penalties to help injury-battered Barcelona overcome the absence of Messi and four more first-choice players.
"Those of us who are left have to take care of ourselves," Iniesta said. "When we reach April or May it will be a question of having everyone doing their part."
Elsewhere, Mexico forward Carlos Vela found the net four times to rally Real Sociedad back from a two-goal deficit for a 4-3 victory against 10-man Celta Vigo.
Ronaldo and Messi are their teams' undisputed leaders and the two top scorers in the sport, but their teammates showed they have more than enough attacking talent to get by without them, especially against the lesser league sides, by combining for eight goals without the scoring aces.
Ronaldo is vying to end Messi's unprecedented run of four straight Ballon d'Or awards. While Messi won't be back from a left hamstring tear until January, Ronaldo, if fit, will have one more chance to impress voters on Wednesday when Madrid hosts Galatasaray in the Champions League before voting for the 2013 award closes on Friday.
Ronaldo had already directed two shots on target when he ran forward to toe Isco's bouncing cross inside the far post with his outstretched left boot for his league-leading 17th goal in 14 rounds.
The goal tied Ronaldo with former striker Hugo Sanchez as the Madrid's fourth all-time leading scorer in league play with 164 goals. Ronaldo did it in 149 games, while Sanchez needed 207. Raul Gonzalez holds the record with 228 goals.
With Almeria showing some fight, Ronaldo left the match and went straight to the changing room.
Benzema curled in a pass from Ronaldo's replacement, Jese Rodriguez, in the 61st, Bale pounced on a defensive gaffe to seal the result in the 72nd, and Isco placed a long-range strike inside the post in the 75th. Morata chipped the goalkeeper six minutes later.
Barcelona leads Madrid by six points. Atletico Madrid also trailed the defending champions by six points before it hosted Getafe late.
Messi paraded his record third Golden Boot for most goals in Europe's domestic leagues last season before taking his seat at Camp Nou.
Without Messi, Xavi Hernandez, Dani Alves, Jordi Alba, and goalkeeper Victor Valdes, Barcelona still dominated a Granada side that had lost only once away this season, to remain unbeaten with a league record of 13 wins and one draw.
"Barcelona was missing players? I didn't realize it," Granada coach Luis Alcaraz said.
Iniesta drove his spot kick low and inside the right post in the 20th, and Fabregas took his turn to blast the ball into the top right corner in the 40th.
Granada played a man down from the 66th after Manuel Iturra received his second booking.
Barcelona replacement goalkeeper Jose Pinto got his chance in the 71st when he beat Allan Nyom one-on-one, starting a counterattack that finished with Neymar passing for Alexis Sanchez to equal Messi as Barcelona's leading scorer in the league with eight goals.
Fabregas set up Pedro Rodriguez for his seventh league goal in the 90th.
Vela started Sociedad's comeback against Celta from 3-1 down by heading in a free kick in the 61st, and Celta defender Andreu Fontas was dismissed for his second yellow card four minutes later.
Vela levelled at 3-3 in the 78th and held off his marker to collect Antoine Griezmann's lobbed pass to roll in the dramatic winner in the 81st.
"You work hard each game to help as much as you can and today was a great day for me," Vela said. "And, fortunately, my goals got us the win, because if not it would have been bittersweet."
Barcelona visits Ajax in the Champions League on Tuesday, while Sociedad visits Shakhtar Donetsk on Wednesday.
