After the 2007 season, the team decided to remove the "Devil" from its name and it became the Tampa Bay Rays, per MLB. The logo was redesigned to show a ray of light. The team didn't completely step away from their aquatic heritage though — there is still a tank full of stingrays that fans attending the game can touch. 

Their earlier futility was actually helpful. They drafted wisely, getting such important players as Evan Longoria, Carl Crawford, Ben Zobrist, James Shields, Matt Garza, and David Price (via Baseball Reference) that catapulted them from being one of baseball's worst teams to one of the best. 

The name change seems to have worked. They have made the World Series twice since becoming the Rays (per Brittanica), and have been able to contend despite not having the deep pockets that other teams do. Thanks to young superstars like Wander Franco, Randy Arozarena, and Austin Meadows, the Rays have a rather bright future with a potential World Series win in the not-too-distant future.
