Matias Vuoso and Angel Reyna scored second-half goals to give America a 2-0 win at league-leader Atlas in the fourth round of the Mexican Clausura championship on Saturday.
Vuoso opened the scoring in the 71st minute and Reyna made it 2-0 in the 84th as America gave new coach Carlos Reinoso a win in his first game in charge after replacing Manuel Lapuente this week.
America remains bottom of Group 2, but moved to four points to close the gap to Atlas atop the group.
In Pachuca, Droguett scored with a low shot to give Cruz Azul the lead in the 40th minute. Cruz Azul raced away after the break, with Julio Dominguez adding a second after Miguel Calero could only parry an Emanuel Villa free kick in the 62nd minute.
Substitute Castro curled in a shot from long range in the 75th and Villaluz completed the rout after stepping inside his marker in the box in the 87th.
The win put Cruz Azul atop Group 3, with Pachuca stuck on five points in Group 2.
In Saturday's other matches Carlos Esquivel scored the only goal of the game to give Toluca a 1-0 win at previously unbeaten Tigres, while Santos moved level with Tigres on points atop Group 1 after a 2-1 win at Chiapas thanks to first-half goals from Christian Benitez and Darwin Quintero. Omar Flores scored for Chiapas in the 72nd.
Elsewhere, Efrain Cortes scored the winning goal in the 59th minute in a 1-0 win for Queretaro at home against Necaxa, while an own goal from Yasser Corona in the 40th minute and a second from Christian Bermudez in the 88th gave Atlante a 2-0 home win against ten-man Puebla. Jose Gonzalez was sent off for Puebla in the 35th minute.
The 18 teams in the Mexican Primera Division are split into three groups, with the top two in each group making the end-of-season playoffs to decide the champion. The two clubs best-placed in the general table which have not qualified from their group also make the playoffs.
Atlas stays top of the general standings ahead of Sunday's fixtures when San Luis could take over if it wins at Morelia. UNAM Pumas hosts Monterrey in Sunday's other match.
