Jaime Edmondson, girlfriend of Rays third baseman Evan Longoria, announced the birth of their daughter early Friday evening via her Twitter account.
"@Evan3Longoria & I are so proud to welcome Elle Leona Longoria to the world ... born 2/20/13 7:21 p.m. 4.1 lbs 18 inches."
Edmondson also tweeted that the baby, born more than a month premature, is "strong & we look forward to the day she gets to go home."
In her tweet, Edmondson said Longoria left to return to the Rays. He missed his third day of workouts Friday.
Earlier in the day, Rays manager Joe Maddon said he expected Longoria to return at some point over the weekend but would not be concerned if he needed a few more days with his new family.
The Rays are set to open their Grapefruit League schedule Saturday with split-squad games at Charlotte Sports Park against the Pittsburgh Pirates and in Fort Myers against the Boston Red Sox.
Longoria was not on the roster for either game and could need a few days of workouts before playing in a game.
C Chris Gimenez is playing third base against the Pirates, while Sean Rodriguez is starting at third base against the Red Sox.
"It's an opportunity to see somebody else (at third base) this early on," Maddon said. "With (Longoria) I just want to make sure he's ready for the beginning of the season."
