MEXICO CITY, May 22 (Reuters) - Pachuca lifted Mexico's Clausura title on Sunday when Uruguayan Richard Nunez scored a penalty to clinch a 1-0 win over San Luis.
The win gave Pachuca their fourth national title in seven years, but the two-legged final between two of Mexico's less fashionable clubs yielded meagre entertainment value and just one goal.
Both teams seemed determined to avoid taking risks during the second leg, played at Pachuca's Hidalgo stadium.
San Luis were slightly more inclined to attack and striker Jesus Mendoza went close in the first half with a swivelling shot but Pachuca goalkeeper Miguel Calero palmed the ball to safety.
Pachuca's clearest opportunity from open play came on 71 minutes, when Luis Angel Landin broke free of his markers but crashed his shot onto a post.
The penalty incident followed on 79 minutes when Andres Chitiva was bundled over by San Luis substitute Angel Reyna and referee Armando Archundia pointed to the spot.
'I felt very calm and very sure that I would be able to put it away,' Nunez told reporters.
Pachuca put all their players behind the ball and concentrated on defending their lead. San Luis had little answer to their defensive tactics, and Calero was not troubled again.
The drab final was in sharp contrast to Pachuca's thrilling semi-final victory over Guadalajara, clinched with a last-minute goal by Colombian defender Aquivaldo Mosquera.
Pachuca's previous Mexican titles were the Invierno championships of 1999 and 2001, and the Apertura title of 2003.
