Boca Juniors claimed a share of first place in the Argentine league and extended their unbeaten run to 36 matches with a 2-0 victory over San Lorenzo in a Buenos Aires derby Sunday.
Tigre has also won 10 points from four matches following a 1-0 victory over Lanus on Sunday. Boca and Tigre are two ahead of Velez Sarsfield, Estudiantes and All Boys.
In other matches Sunday, Colon and Union drew 2-2, and Arsenal and Racing played a scoreless draw.
Boca had several chances early, but most of the opportunities in the scoreless first half belonged to San Lorenzo. The second half was also lackluster until Juan Sanchez Mino broke through in the 59th with a 15-meter (yard), ground-hugging shot. Pablo Mouche added the other goal in the 87th.
Uruguay forward Santiago Silva started up front in his first match for Boca in the league.
Silva was signed from Italian club Fiorentina, where he seldom played. The agreement announced in January said Silva could play only in Copa Libertadores games. The Argentine Football Association ruled last week he could also play the in the league due to the injury of Boca player Nicolas Colazo.
The move has angered Silva's former Argentine club, Velez, which is also a top contender for the league title.
Diego Morales scored in the third minute to seal Tigre's victory.
In Colon's draw, Ivan Moreno y Fabianesi scored two first-half goals, but Diego Jara and Nicolas Correa added second-half goals for Union.
On Saturday, All Boys and Velez drew 0-0, Estudiantes defeated San Martin 1-0 and Argentinos Juniors overwhelmed Independiente 3-1.
Estudiantes won thanks to an own-goal by Diego Sosa, and Nicolas Batista, Fabian Bordagaray and Pablo Barzola scored for Argentinos. Roberto Battion hit one back for Independiente.
Coach Ramon Diaz resigned after Independiente's fourth straight league loss.
On Friday, Belgrano defeated Newell's 2-0 and Banfield drew 1-1 against Godoy Cruz.
On Monday, Olimpo hosts Rafaela.
