Guerrero, 37, hit 449 home runs over 16 years in the big leagues. Last season, Guerrero hit .290 with 13 homers and 63 RBIs for the Orioles.
Towers is headed to the Dominican to see some amateur players, and D-backs vice president of Latin operations, Junior Noboa, suggested Towers take a look at Guerrero.
"Junior knows him and likes him and says he looks good," Towers said. "Who knows what comes of it. He's out there. Junior knows him well and he's in the Dominican. He said he's in good shape. I'm going to be down there for a workout anyway."
Towers was asked if Guerrero would be a fit as a designated hitter for Arizona's Interleague Play games much like Wily Mo Pena was last year.
"I'll have a little better idea depending on what I see," Towers said.
