PHOENIX -- Desmond Jennings was placed on the 15-day disabled list (retroactive to Sunday) with a small fracture of his left middle finger. In corresponding moves, outfielder Jason Bourgeois was selected from Triple-A Durham and right-hander Alex Cobb (concussion) was transferred from the 15-day to the 60-day DL.
"[Jennings'] knuckle got a little bit big and I guess it's some kind of small fracture," Rays manager Joe Maddon said. "I don't expect him to be gone too long, hopefully not too much longer than the regular 15-day DL. It's unfortunate. We're definitely going to miss him."
Bourgeois, 31, begins his sixth partial season in the Majors with his fifth team.
"Exciting, unexpected," said Bourgeois of his reaction to his promotion. "We've been playing down there well. It's been a fun year. It makes it even better now coming to a ballclub like this. ... Just want to try and do my part and have fun."
Bourgeois has had stints with the White Sox, Brewers, Astros and Royals. When asked why he signed with the Rays, he said he wanted to sign with a winning ballclub.
"I know that sometimes the more you win, those managers like guys with a little more experience," Bourgeois said. "So I tried to go for that. You just never know though. You just hope you find yourself in a good situation. I knew the atmosphere was great. Carl Crawford told me all good things about this place, he kind of pushed me toward here. So it was great."
Crawford and Bourgeois are childhood friends. Bourgeois was hitting .291 with two home runs, 57 RBIs and 21 stolen bases at Durham.
In Jennings' absence, Maddon said he would have a "revolving door" in the leadoff spot and center field will be "wide open" as well, with a lot of players filling in both spots.
