The Milwaukee Brewers promoted outfield prospect Chris Roller to the major league club on Wednesday. In a corresponding move, the Brewers optioned Oliver Dunn to the minors. The 27-year-old made his major league debut Wednesday night when he entered the game in the sixth inning as a pinch-hitter, ultimately striking out in a six-pitch at-bat. The right-handed hitter did a lot of that in his 56 Triple-A at-bats this season, striking out at a 36.2% clip (21 times compared to two walks), while batting .250 with zero home runs and one stolen base. Roller was drafted in 2017, so it's nice when you see a player's perseverance pay off, but as far as fantasy is concerned, he is off the radar for now.
