The Red Sox waited fewer than 24 hours after their season finale to cut ties with embattled manager Bobby Valentine, and now another fiery skipper from an under-performing ballclub could be next in baseball’s the unemployment line.

The Miami Marlins are “aggressively seeking a replacement for Ozzie Guillen,” according to ESPN’s Buster Olney.

In their first season in Miami, Guillen led the new-look Marlins to their worst record since 1999 (69-93) and failed to capitalize on the excitement surrounding the team’s new stadium and big-name free agent acquisitions. But Guillen’s brash style may have done more damage to his relationship with the team’s front office than his team’s on-field performance.

According to a Palm Beach Post report, Marlins owner Jeffrey Loria is facing pressure to fire Guillen from who feel the manager “has brought an unprofessional culture to the Marlins.” Unnamed sources in the report noted Guillen’s notoriously foul mouth and the constant presence of his three adult sons in the clubhouse.

Late last month, deposed Marlins closer Heath Bell was critical of Guillen in a radio interview, saying “It’s hard to respect a guy that doesn’t tell you the truth or doesn’t tell you face-to-face.”

Guillen, who signed a four-year contract before the season, still has three years and $7.5 million left on his deal.

The 48-year-old Venezuelan-American has remained defiant amid rumors of his impending firing. Guillen laughed off questions about his job security in September.

“That’s the last thing going through my mind every day, if I’m going to have a job next year,” Guillen said (via the Associated Press). “I’m going to have a job. I don’t know if it’s managing the Marlins, but I will have a job. I don’t know if it’s managing in the big leagues, but I will have a job.”
