MADRID, April 12 (Reuters) - Barcelona missed the chance to close the gap on Primera Liga leaders Real Madrid after struggling Recreativo twice pegged them back to draw 2-2.
Samuel Eto's gave the visitors the lead after just two minutes, nodding home from close range.
But the hosts hit back when the linesman adjudged Marco Rubén's header crossed the line, after Barca keeper Victor Valdes had fumbled - replays suggesting the goal should not have counted.
Eto'o regained the lead for the Catalan side with a fine solo effort - crashing a shot from outside the area in off the bar.
But again, Barca couldn't hold the lead and Rubén, on loan from Villarreal, claimed his second of the game with an angled header after Valdes found himself out of position.
Barcelona are six points behind leaders Real Madrid, who play Murcia on Sunday.
High-flying Racing Santander piled the pressure on struggling Valencia when a late Mohamed Tchite strike gave them a 2-1 win in the Primera Liga at the Mestalla on Saturday.
Racing took a deserved lead on the hour, midfielder Gonzalo Colsa steering in an angled shot after powering a header against the bar.
Valencia equalised three minutes later when substitute David Villa converted a penalty after fellow striker Fernando Morientes had been brought down in the area.
But Tchite snatched the win when he slotted home at the far post from an offside position after Pablo Alvarez charged down the right and swept a fine pass behind the Valencia back four.
Ronald Koeman's Valencia, who meet Getafe in the King's Cup final on Wednesday, have won just one of their last nine league games and are only six points above the relegation zone in 14th place with all their closest rivals yet to play.
They have won only once at the Mestalla in the last five months and have the joint worst home record in the league with basement side Levante.
Racing remain in fifth place but are now level on 53 points with Atletico Madrid who visit Valladolid on Sunday.
