SAN DIEGO, Calif. – The White Sox are going to try and convince Jeff Samardzija not to be a rental player.

Chicago acquired Samardzija from Oakland in a six-player trade. News on the trade surfaced Monday night at the winter meetings and GM Rick Hahn made it official Tuesday morning.

Samardzija, who grew up a White Sox fan, is a free agent after the 2015 season. Hahn said the White Sox are going to try and change his mind.

"We traded some real good ballplayers, but at the end of the day we felt that this is a premium starter who fit in well in our clubhouse and rotation," said Hahn. "We hope that he is a mainstay for our club over the coming years."

The White Sox sent infielders Marcus Semien and Rangel Ravelo, catcher Josh Phegley and right-hander Chris Bassitt to Oakland. The White Sox received Samardzija and pitching prospect Michael Ynoa.

Hahn said that with Samardzija, Chris Sale and Jose Quintana, the White Sox can match any team's top three starters.

"This is a guy who is a perfect complement to Sale and Quintana," he said. "We feel really good about one through three, like we can stack up against anybody."

Sale and Quintana are left-handed.

It has been a busy off-season for a White Sox team that finished a distant fourth in the AL Central behind Detroit, Kansas City and the Indians. They signed lefty Zach Duke to a three-year deal and first baseman Adam LaRoche to a two-year deal.

Chicago also has reportedly reached a four-year, $46 million deal with closer David Robertson. Hahn declined to discuss Robertson, saying he was still a free agent. Hahn added, "we hope to have some big news later this week."

Hahn said the White Sox have spent most of their available money, but added, "We're not done. We'll just have to try and be more creative."
