MADRID, Sept. 20 (Xinhua) -- Osasuna drew 0-0 with Real Betis at home on Friday to remain undefeated in its first season back in the Spanish La Liga.
Osasuna are on a run of 27 games without a home defeat and might have taken all three points.
The newly promoted side had the better chances and striker Chimy Avila hit the crossbar in the second half.
Avila couldn't beat goalkeeper Joel Robles one-on-one after Osasuna launched a 6-on-2 counterattack following a botched set piece by Betis just before halftime.
Osasuna beat Leganes in its opener and has strung together four draws, including 2-2 against defending champion Barcelona.
The hosts were left in seventh place before the rest of this weekend's matches.
Betis are 13th after keeping its first clean sheet of the season. Betis next host Levante on Tuesday, while Osasuna visit Real Madrid on Wednesday.
Matchday five of La Liga continues Saturday with Barcelona away to Granada and Atletico Madrid home to Celta Vigo.
