The top three sides in the overall table plus the top two teams in Group B were beaten over the weekend, a flurry upsets tightening the standings and rewarding Guadalajara for its first back-to-back victories since the full season began last summer.
Five of the top eight clubs were beaten:
First-place Pumas UNAM (7-1-4) was stunned by three goals in the first 33 minutes, two by Antonio Salazar, in a 3-1 loss at last-place Jaguares.
No. 2 Morelia (6-3-3) lost for the second time in three games -- a 3-1 decision at home against Group 2 cellar-dweller Pachuca -- to dip to third, still four points off the lead.
No. 3 Cruz Azul (6-3-3) gave up a first-minute goal (to Carlos Quintero) and never recovered, falling, 3-0, at Santos Laguna, which had lost its previous five.
No. 6 Atlante (5-6-1), the Group 2 leader, gave up both goals in a 2-0 loss to UANL Tigres after Alex Diego's red card and dropped to eighth overall and three points behind America in the group standings.
No. 7 San Luis (3-3-7) let an early two-goal lead disappear in a 3-2 loss to Gallos Blancos, which is seeking to avoid relegation to the second-tier Liga de Ascenso. The Gladiadores fell out of the playoff zone, to 11th place.
Tigres (6-1-5), again without Los Alamitos' Jonathan Bornstein, vaulted to second overall, two points behind Pumas, and America strengthened its hold on a postseason spot with a wild 5-4 triumph over Puebla. Angel Reyna netted a hat trick -- he leads the Primera Division with nine Clausura goals -- and Vicente Sanchez added a pair for the Aguilas, who had a 4-0 lead by the 33rd minute.
Marco Fabian de la Mora's 70th-minute free kick lifted Guadalajara (4-2-6) to a 2-1 triumph at Necaxa, pushing Chivas to seventh, just their second time in the top eight since summer.
MORE BIG GAMES: How often is the Super Clasico not the game of the week? There's plenty at stake when America visits Guadalajara on Saturday -- both teams are fighting for playoff berths -- but there's a bigger game Sunday: No. 1 Pumas vs. No. 2 Tigres. It's the second 1-vs.-2 showdown for Pumas, which beat Morelia, 1-0, in that situation March 13.
COPA CALL: Monterrey takes a 2-1 lead over Cruz Azul into Wednesday's second leg, in Mexico City, in a CONCACAF Champions League semifinal. The Rayados have been the best team in the competition, going 8-0-1 in group play and the knockout stage -- 3-0-0 against fellow Mexicans, twice beating Toluca, 1-0, in the quarterfinals.
The victor will take on Real Salt Lake, which Tuesday became the first Major League Soccer club to reach the regional club championship series since the change to a “league” format in 2008, finishing off a 3-2 aggregate victory over Costa Rica's Saprissa.
America and Jaguares have important Copa Libertadores group games Wednesday. The Aguilas (2-2-0), second in Group 3, are home against first-place Argentinos Juniors (2-1-1), and a victory would all but ensure the expected berth in the round of 16. Jaguares (2-2-0), also home, likely need to upset defending champion Internacional (3-0-1) in Group 6 to stay alive. San Luis (1-2-2) plays its Group 1 finale April 19.
AMERICANS ABROAD: Sacramento-born Miguel Angel Ponce returned after missing 10 weeks with a torn leg muscle, playing the final 19 minutes in Guadalajara's victory. … Jose Francisco Torres was in the lineup for Pachuca's big win, but Herculez Gomez did not feature. … San Diego's Joe Corona scored the first goal in Club Tijuana's Liga de Ascenso triumph over Atlante Neza. … Sonny Guadarrama started both of Merida's Liga clashes, and Marco Vidal was in Leon's lineup.
ETC.: Jaime Ayovi's 73rd-minute strike lifted Toluca (4-4-4) to a 1-1 draw with fifth-place Monterrey (6-4-2), which went ahead through Aldo de Nigris in the fourth minute. … Gallos Blancos (4-6-2) took another step toward survival, rallying from a quick two-goal deficit to beat San Luis, 3-2. Carlos Bueno had the tying and winning goals, the latter in the 87th minute. If the Queretaro-based club loses its last five games, Necaxa (3-7-2) would need three wins in its final five to catch up on the percentage table. … Atlas and Estudiantes Tecos shared the points in a Guadalajara derby, with Mauro Cejas scoring his sixth for the Owls and Honduran forward Carlo Costly getting his first for Atlas. … Santos' Quintero was assessed a six-game suspension Tuesday for striking Cruz Azul's Rogelio Chavez during Saturday's clash. Quintero, who is black, says he was racially provoked. Santos is appealing the sanction.
LIGA DE ASCENSO: Irapuato and Leon put some distance on the rest of Mexico's second league with victories, and Tijuana returned to the No. 3 spot in the standings with a victory over last week's No. 3.
Leon (8-1-4), which crushed Correcaminos, 4-0, behind a Blas Perez hat trick, can vault to the top spot with a win Sunday at eighth-place Cruz Azul Hidalgo. The Esmeraldas, who are 15-1-7 since an 0-6-1 start to the Apertura, are two points behind Irapuato (9-2-3). The top team won, 2-1, at Leones Negros on two Kevin Favela goals and has its bye this weekend. ...
Corona and Luis Enrique tallied for Tijuana (6-2-5) in its 2-0 win. Atlante Neza (6-3-5) is fourth, behind of goal difference. ...
Eder Pacheco scored his 22nd goal of the full season -- 21 in the Liga, one in the Primera -- but Veracruz's bid to beat visiting Alacranes de Durango (and vault to third) failed with Damian Macaluso's last-minute own goal in a 2-2 draw. Alacranes has won just once in its last six games, over Leon. … Edwin Borboa scored an early goal for the third straight game, starting Indios toward a 2-0 victory over La Piedad, ending the Ciudad Juarez club's five-game winless streak.
