Choi was selected by the Angels in the major league portion of the Rule 5 draft on Thursday, JJ Cooper of Baseball America reports.
Choi has spent six years in the Mariners' minor league system, and in 2015 he played 18 games with Triple-A Tacoma. He batted .298/.403/.421 with 17 hits and 16 RBI's in those 18 games. He hasn't shown a ton of power in his career but he's been an efficient bat a majority of the time. He'll start the 2016 season behind Albert Pujols, CJ Cron, and possibly Efren Navarro.
