The Argentine league continues to be an uncertainty because no one seems to assert their dominance. League leaders Lanús fell on Friday night against an inspired Argentinos Juniors side. That left the door wide open for Ricardo Gareca’s Vélez Sarsfield side to take the top spot in the Clausura tournament as it reaches the halfway point. El Fortín came to the Buenos Aires neighborhood of Boedo to face a San Lorenzo side that was eliminated from Copa LIbertadores play at midweek and saw coach Miguel Ángel Russo step down. It was a home game by default as the San Lorenzo fans jeered and insulted their team all throughout the match. They also were resentful at club brass starting with president Rafael Savino as well as the investment group that has been in place for the past year which was led by Argentine media mogul Marcelo Tinelli. Defending champ Boca Juniors seems to have lost their bid to repeat as domestic champs after losing to Estudiantes in La Plata. The loss puts Boca at an eight-point deficit, which leaves them in a position to play spoiler at home in The Superclásico against arch-rivals River Plate. Los Millonarios had the opportunity to go be two points from the top with a win against Gimnasia La Plata, but it would be a tough challenge as well as a game they could easily overlook. They also were being threatened by their fans with chants stating that if they did not win in La Bombonera, to not bother coming back. The news was somewhat put on the backburner as Angel Cabrera had become the Latin American golfer to win the Masters. No fear for River fans as Mauro Díaz equalized early in the second half and took the lead. Gimnasia would equalize close to the end and almost took the three points away from the Monumental; further incensing the the River Plate faithful Independiente in the meantime were able to bounce back from the 5-1 thrashing at the hands of the Granate last weekend. Tigre let three points slip away in injury time when Matías Giménez missed a penalty kick.
