Detroit acquired Baker from the Cubs on Aug. 5 as an extra right-handed bat in exchange for what was supposed to be two players to be named later. Baker batted .200 in 15 games for Detroit before the Tigers designated him for assignment on Aug. 31. Detroit worked out a trade to send him to Atlanta that day.
The players were scheduled to be decided upon by Oct. 31. In the end, the Cubs get one player in Carreno, who was ranked No. 11 among the Tigers' top prospects.
The 21-year-old right-hander went 9-8 with a 3.23 ERA in 27 starts for low Class A West Michigan, marking his second season with the Whitecaps. He allowed 129 hits over 139 1/3 innings with 28 walks and 119 strikeouts.
