League-leading Velez Sarsfield failed to stretch its lead at the top of the Argentine Clausura championship on Sunday after losing 2-1 at mid-table Tigre.
Denis Stracqualursi gave Tigre a 1-0 lead in the 26th, converting a penalty for his 11th goal of the season. Velez equalized with Ricardo Alvarez's 25-yard strike in the 63rd, but Gaston Diaz restored Tigre's lead two minutes later with a sensational 20-yard rising shot from the right wing.
Velez has 30 points from 16 matches, three more than Godoy Cruz, which has a game in hand and could move into a share of the lead with a victory Monday against Gimnasia. Also on Monday, Lanus plays Huracan. Three rounds remain.
