Miller, 28, was the odd man out when the team promoted first base prospect Jake Bauers to the majors. The veteran hit 30 home runs in 2016, but he has been unable to duplicate that performance since. He’s gone on the disabled list three times in the past two seasons. In 174 plate appearances this year, he was batting .256 with a .322 on-base percentage and .429 slugging percentage.
The 27-year-old Choi was just optioned to Triple A Sunday, a day after hitting a grand slam for the Brewers. In 32 plate appearances for Milwaukee this year, he owned a .233/.281/.500 line with two home runs.
The Rays optioned him to Triple-A Durham where he’ll add depth to the division-leading Bulls and provide insurance if a major leaguer like Bauers or C.J. Cron gets injured.
