PACHUCA, Mexico -- Edgar Benitez scored two minutes into injury time and Pachuca beat Cruz Azul 1-0 to win the CONCACAF Champions League title and its third continental crown in four years.
Benitez's goal ended 92 minutes of frustration for Pachuca, which dominated possession, but created only a handful of dangerous chances.
It finished tied 2-2 on aggregate but won the title on away goals after a 2-1 loss in the first leg in Mexico City last week.
"We knew that it was going to be very tough but we never gave up," Benitez said. "We kept fighting until the end and finally the goal came in the final minute."
The loss extended Cruz Azul's inability to claim a title, marking the fifth straight time it had reached the finals of a championship only to lose. It was the second straight year it had reached the Champions League title series, having lost last year to fellow Mexican side Atlante.
La Maquina, which is tied with Mexico's America for the most CONCACAF club titles with five, has not won a crown since the Mexican league Invierno championship in December 1997.
"Life isn't over. Cruz Azul is going to keep on fighting," manager Enrique Meza said. "It's true that we've been through some tough things but we are professionals and you have to keep your head high."
Pachuca pressed throughout and finally converted when Damian Alvarez's ball toward the top of the area was advanced with a flicked back heal by second-half subsitute Ulises Mendivil. Benitez settled the ball, spun right one step inside the area and beat Cruz Azul goalkeeper Jose Corona with a low, left-footed shot.
"When we saw the ball hit the net, it was madness," Pachuca manager Guillermo Rivarola said. "There was tons of emotion. We all wanted to hug each other as the goal gave us the championship and the ticket to the Club World Cup. I really can't describe it. "
Until then, Corona had thwarted Pachuca, including coming off his line to intercept Alvarez's attempted cross into Benitez at the left post in the 68th. Pachuca played nearly the entire second half in Cruz Azul's end, but produced few dangerous chances that tested Corona until injury time.
Juan Carlos Rojas appeared to have Pachuca's best chance late, creating space for himself seven meters from goal but sending his left-footed shot high in the 82nd.
The result confirmed Mexico its 26th CONCACAF club championship, four times more than the next closest nation (Costa Rica, six) and its fifth straight.
Cruz Azul entered the match having been eliminated from the Mexican Liguilla playoffs in the final round of the season on Saturday, with a 1-1 draw at home against Chivas de Guadalajara.
Pachuca, conversely, claimed last Liguilla berth with a 2-1 win at Tigres on Saturday, and will face Monterrey on Saturday.
Both sides produced little in the first half with Cruz Azul testing goalkeeper Miguel Calero in the second minute but not generating much after that. Javier Orozco dribbled past Javier Munoz and hit a shot that Calero blocked but couldn't hold, eventually covering the ball before Emmanuel Villa could pounce on the rebound.
Pachuca had more of the possession and chances, including its best opportunity when Damian Manso ran onto a cross at the back post in the 10th minute only to badly mis-hit the ball and send it wide back across the goal.
The closest either came was when Pachuca's American midfielder Jose Torres looped a cross off the topside of the crossbar in the 24th.
The victory also made Pachuca the first team to qualify for the Club World Cup in Abu Dhabi, United Arab Emirates in December.
