Pumas forward Nicolas Castillo is the talk of the Mexican league after scoring three goals in his team's 4-2 romp over Puebla.
The 25-year-old Chilean was one of three international players to score two or more goals in the 15th round of play in the 2018 Clausura tournament.
Castillo now has 10 goals this season, moving into second place on the scoring list behind Cape Verdian Djaniny Tavares, who has nailed 14 goals.
Lucas Cavallini, a Canadian who plays for Puebla, scored two goals and came close to nailing a third, firing a shot that came off the goal post.
The 25-year-old Cavallini moved into the No. 3 spot on the tournament scoring list, passing Frenchman Andre-Pierre Gignac and Peruvian Raul Ruidiaz, both former scoring champions in Mexico.
On Saturday, Cruz Azul forward Martin Cauteruccio celebrated his 31st birthday by scoring two goals to help his team tie the Tigres 2-2.
The Uruguayan scored his first goal in the 40th minute of the match on an assist from Ecuadorian Angel Mena.
Cauteruccio blew past two Tigres defenders to score his second goal in the 88th minute, beating goalkeeper Nahuel Guzman.
The Cruz Azul forward had not scored any goals heading into the match against the defending champion Tigres at Estadio Universitario.
Cauteruccio's contract with Cruz Azul is up at the end of the 2018 Apertura tournament.
Pachuca, for its part, seems to have found the scoring formula with Japan's Keisuke Honda and Argentina's Sebastian Palacios.
Honda and Palacios have scored seven goals each, accounting for seven of the nine goals scored by Pachuca in its past two tournaments.
Of the 23 goals scored in this round of play, international players accounted for 20.
