Boca draw 4-4 at Velez
Veteran Martin Palermo confirmed to Argentina coach Diego Maradona his form with one of Boca's goals and, despite also missing a penalty, tied his club's all time goals record of 218 held by Roberto Cherro since 1938.
Not to be left out, Chile defender Gary "Pitbull" Medel popped up on the right to equalize in the 89th minute after Velez had fought back from 3-1 down in the best match of the Argentine season so far.
Both teams served up a feast of attacking soccer as they recovered from poor weekend results, Boca having conceded a stoppage-time equaliser in a 1-1 home draw with Estudiantes and Velez having lost 3-2 at Huracan.
The result leaves Boca in mid table while Velez, with 12 points from seven matches, took a share of the lead in the standings with Godoy Cruz, who are at home to Lanus on Wednesday, and Colon, away to title holders Banfield on Thursday.
Midfielder Victor Zapata headed Velez in front from a free-kick after a quarter of an hour of the match at Velez's El Fortin ground in the capital.
Boca then scored three unanswered goals with left back Luciano Monzon equalising from a tight angle in the 36th minute.
Palermo, who had a 26th-minute penalty saved by German Montoya, struck in the 39th from Juan Roman Riquelme's square pass from the left and forward Nicolas Gaitan ended a fine move with a brilliant third just before the hour.
Silva pulled one back with a header in the 62nd minute and substitute Juan Martinez rifled in an equaliser in the 74th.
The 29-year-old Uruguayan striker got his second goal, and fifth this year, when he chased a long ball out of defence, shrugged off Boca's Brazilian centre back Luiz Alberto and shot under advancing keeper Javier Garcia to put Velez ahead again.
Medel, who would not have been playing had Chile's World Cup warm-ups on Wednesday not been cancelled because of Saturday's devastating earthquake in his home country, then pounced on the rebound from Montoya, who had dived to save Riquelme's low left-footed shot from outside the box.
