SANTIAGO, Oct. 23 (Xinhua) -- Lucas Di Yorio and Charles Aranguiz scored late as Universidad de Chile salvaged a 2-2 home draw with Lanus in the first leg of their Copa Sudamericana semifinal on Thursday.

Rodrigo Castillo put the visitors ahead in the 25th minute by intercepting an errant pass and lifting a 40-yard shot over stranded goalkeeper Gabriel Castellon.

Twenty-six-year-old striker Castillo then doubled the lead with a close-range effort after Eduardo Salvio's cross.

But the hosts emerged from the halftime break with renewed purpose and Di Yorio pulled a goal back just after the hour when he bundled home after a scramble in the six-yard box.

Charles Aranguiz equalized with a stoppage time penalty after Agustin Cardozo handled in the area, prompting boisterous celebrations from the home fans.

The decisive second leg will be played in Buenos Aires next Thursday. ■
