BARCELONA (Reuters) - Lionel Messi marked his record 506th appearance for Barcelona in La Liga by scoring a penalty but the Catalans could only draw 1-1 with Cadiz on Saturday after conceding a spot-kick late on.
The Argentine overtook former team mate Xavi Hernandez in the all-time list of Barca appearances in the league and opened the scoring in the 32nd minute by calmly passing the ball into the bottom corner from the spot after Pedri had been tripped by Cadiz's Iza.
Fielding the same starting 11 that had been out-classed 4-1 by Paris St Germain in Tuesday's Champions League last-16 first leg on Tuesday, a rusty looking Barca failed to build on their lead despite having 81% possession and taking 21 shots at goal.
They paid the price when Clement Lenglet gave away a penalty for striking Cadiz forward Ruben Sobrino as he tried to clear the ball.
Cadiz midfielder and former Real Madrid trainee Alex Fernandez made no mistake from the spot in the 89th minute to equalise for the visitors with their first shot on target.
The draw disrupted Barca's run of seven straight league wins as the Catalans failed to take advantage of La Liga leaders Atletico Madrid's surprise 2-0 defeat by Levante a day earlier.
Barca are third in the standings on 47 points, trailing leaders Atletico by eight points and second-placed Real Madrid by five points.
"This hurts a lot because after Atletico's defeat we had the chance to get right back in the race," said Barca defender Gerard Pique.
"We had loads of chances, they had hardly any so to concede a late goal like that is difficult to swallow. Given the state of mind we went into the game today, we really had to get the three points."
Cadiz are 14th on 25 points but have pulled off a remarkable feat in earning a win and a draw in their two games against Barca since returning to the top flight.
"Picking up points here is very difficult but we had a clear plan, we knew we couldn't come here and attack them and open ourselves up," said goalscorer Fernandez, whose brother Nacho still plays for Real Madrid.
"You know that Barca are always going to take a lot of shots at home so this is a great point for us. Anything I can do to help my brother out is great, although the most important thing for me is to help Cadiz."
