If you can't beat ‘em, join ‘em.

That’s the move super middleweight contender Jaime Munguia has made, as he’s handing the coaching keys of his career to Canelo Alvarez’s lifelong confidant Eddy Reynoso nine months after losing to the Mexican superstar and six weeks after suffering the upset of the year in a shocking knockout loss to Bruno Surace.

Reynoso announced the development on Wednesday, which signals an end, for now, to Munguia’s much-desired rematch down the line against Alvarez.

“Yes, right now we’re working,” Reynoso told TV Azteca in Spanish. “We’ve been working with him for a week. We met with Mr. Fernando Beltran, with Munguia and his dad to see if we can work with him. And now we’re here getting to know each other and seeing what he likes to work on and seeing the different points of view. I think we can have a very good partnership.”

Reynoso also clarified if Alvarez and Munguia have already crossed paths since the union.

“No, not yet,” said Reynoso. “Saul is barely getting started on physical training. Jaime already started to loosen up in the gym and work on some technical things. They haven’t run into each other.”

The head coaching change marks yet another move in the corner for the 28-year-old Munguia (44-2, 35 KOs). Ahead of his ninth-round knockout win against John Ryder last January, Munguia moved on from fellow Tijuana, Mexico native and Hall of Fame fighter turned coach Erik Morales after a five-year run and instead bestowed training duties to Hall of Fame coach Freddie Roach.

Roach was Munguia’s trainer in the Alvarez fight in May, when Munguia was knocked down and fought admirably to a unanimous decision loss.

After the Alvarez loss – which Canelo claimed he carried his Mexican countryman out of respect – Munguia reunited with Morales, citing the need to train in the high-altitude terrain of Big Bear, California, where he’d previously trained after purchasing the gym once owned by Abel Sanchez, Gennadiy Golovkin’s former coach.

Munguia and Morales reunited in September to knock out Erik Bazinyan in 10 rounds but were on the wrong end of the knockout themselves in December. That’s when the little-known Frenchman Surace struck lightning in a bottle and landed a one-punch, sixth-round knockout in a fight that he was already knocked down in and losing by a landslide.

Earlier this month, Beltran, Munguia’s Mexico-based promoter, told The Ring that a rematch between Munguia and Surace was targeted for April 12 in Mexico.

As for Reynoso, Munguia is just the latest marquee addition to his stable. Late last year, The Ring and WBO junior welterweight champion Teofimo Lopez also added Reynoso to his team.

Over the last three fight camps, Reynoso and Alvarez have moved training from San Diego to an isolated area in Truckee, California, a town in Northern California near Lake Tahoe that sits at 5,817 feet above sea level.
