Carlton was called up by the Tigers for the first time Saturday.
Carlton doesn't come with much prospect pedigree, as he was selected 965th overall in the 2017 draft and has pitched almost exclusively in relief in the minors. He's looked good in 49 innings for Triple-A Toledo this season, riding a 25.0 percent strikeout rate and 5.2 percent walk rate to a 3.12 ERA.
