The Miami Marlins will keep right fielder Giancarlo Stanton and build around him as they try to improve on a National League-worst 2013, new general manager Dan Jennings says.

"Mr. Stanton is not available," Jennings said in an interview with SiriusXM Radio over the weekend. "He is going to be in right field at Marlins Park, and [we're] looking forward to having a big year with him. We're excited."

Stanton, 23, hit .249 with 24 home runs and 62 RBIs in his fourth season in 2013. He missed 36 games because of a hamstring injury a year after posting career highs in batting average at .290 and home runs with 37.

"We think it's going to be a lot of fun building around him and what he can mean to this ballclub and that city," Jennings said.
