Jones, 37, made five All-Star teams and won 10 Gold Glove Awards in center field over parts of 17 seasons with the Braves, New York Yankees, Texas Rangers, Los Angeles Dodgers and Chicago White Sox. He's a .254 career hitter with 434 home runs and 1,289 RBIs in the majors.
Jones hit .197 with 14 homers during his last big league stop with the Yankees in 2012.
He has hit .232 with a combined 50 homers over the past two seasons with the Tohoku Rakuten Golden Eagles in Japan.
Boras said Jones is looking for a job as a part-time outfielder/first baseman and a right-handed bat off the bench.
"He wants to play in the big leagues again," Boras said. "He's still got his power. If you can hit 25 home runs in Japan, you're doing something."
The Boston Globe first reported of Jones' pursuit of a big-league job Sunday.
