Marlon 'Chito' Vera has split from longtime trainer Jason Parillo and is now training with the team of Raul Rosas Jr. as he looks to end a losing streak. Vera described the decision as difficult but said there was no falling out with Parillo, framing the change as a personal desire to avoid career regrets.
Marlon "Chito" Vera has made a significant change to his corner, parting ways with longtime trainer Jason Parillo and linking up with the team behind rising bantamweight Raul Rosas Jr. as he attempts to reverse a recent run of losses.
Vera characterized the split as a difficult personal decision rather than the result of any conflict with Parillo, framing the move as a necessary step to avoid looking back on his career with regret. The Ecuadorian veteran has been one of the more recognizable names in the bantamweight division, but a losing streak has added urgency to his search for a fresh start.

Rosas Jr., the 21-year-old American prospect known as "El Nino Problema," currently trains out of 10th Planet Jiu Jitsu Las Vegas and holds a 12-1 record with a divisional ranking of 12th in the bantamweight division. At five-foot-nine with a 67-inch reach, Rosas Jr. has built his reputation on a relentless grappling game, averaging over four takedown attempts per 15 minutes and posting more than one submission attempt per 15 minutes throughout his young career. Vera's decision to embed himself within that environment signals a clear shift toward a grappling-heavy training philosophy.
Why it matters
- Vera arrives at a crossroads, and the training camp change suggests a deliberate tactical reset rather than a minor adjustment
- The 10th Planet system is known for its submission-oriented approach, which could reshape how Vera engages in future bouts
- At just 21, Rosas Jr. represents one of bantamweight's more promising prospects, and his team now gains a seasoned veteran presence in the gym
- The move raises questions about where Vera fits in the divisional rankings picture if the new setup reignites his form
