The club called up De La Rosa after his successful season for Triple-A Durham, where he recorded 20 saves and posted a 2.79 ERA.
"I'm just obviously blessed to be here," De La Rosa said. "I've had a lot of people pulling for me. It just worked out, and I couldn't be happier."
De La Rosa appeared in one Major League game this year for Tampa Bay, giving up five runs in one inning against Boston. Knowing that he wouldn't be staying up in the big leagues very long during his previous stint, De La Rosa had packed a small bag of clothes to get him through the trip, but he has a much bigger bag this time around.
"I'll be good for the rest of the time, I'm sure," De La Rosa said.
His single outing with the Rays was far from expected, but De La Rosa has appeared in clutch situations in the Majors before, including the memorable "Game 162" against the Yankees last season, when he tossed 1 1/3 scoreless innings to keep the Rays in the game.
"Just be ready," De La Rosa said. "That's kind of how I've been taking it these last three years. I'm just going to do what I do and hopefully I get put in those situations. If I don't, I'll help my team in any way I can."
Tampa Bay also called up Stephen Vogt, who becomes the team's fourth catcher. Vogt spent some time with the Rays this season, going 0-for-17 at the plate, but he fared much better for Durham, hitting .272.
