Choi signed a minor league contract with the Orioles on Tuesday, MASN's Roch Kubatko reports.
The 24-year-old first base prospect washed out of the Mariners system, but the Orioles thought enough of him to extend an invite to spring training. He has always shown a good approach in the minor leagues, but he probably doesn't have quite enough bat to make it as a big league regular at first base.
