Andrus, who is coming off a down season where he hit a career-low .263, has been the subject of trade rumors since the end of the regular season.
Rangers officials privately confirmed their support for Andrus and Wednesday Boras affirmed it.
"I would doubt it," Boras said at the winter meetings of the possibility of Andrus being traded. "His standing with the Texas Rangers is good. I have no belief that he would be traded."
Andrus battled through arm problems and came in a little overweight in 2014. In 157 games, he scored only 72 runs after scoring at least 85 each of the previous four seasons. He also tied for the league lead with 15 caught stolen-base attempts.
Andrus' name was linked to several teams that needed shortstops, but the Rangers have issues trading him because they would need a team to pick up his huge contract extension (eight years, $118 million) and his potential replacements might not be ready to play.
Jurickson Profar missed last season with a severe shoulder injury and was shut down several times during rehab stints. Luis Sardinas is probably one year away from being ready for the big league roster, and the rest of the middle infielders in the farm system are too valuable to trade.
GM Jon Daniels has talked about finding fits to upgrade a club that is coming off a 95-loss season, but when it comes to the starting shortstop, the commitment remains strong.
