The Washington Nationals are integrating young pitcher Jackson Kent into their Major League roster. Initial reports indicated the team was set to promote the 23-year-old left-hander from Triple-A Rochester to fill a rotation spot following the release of veteran Zack Littell. Subsequent roster moves confirmed the team designated veteran right-hander Miles Mikolas for assignment due to a difficult season. Mikolas, 37, struggled during his first year with the team, posting a 3-9 record and a 5.82 ERA across 25 appearances. The veteran, who previously played for the San Diego Padres, Texas Rangers, and St. Louis Cardinals, as well as the Yomiuri Giants in Japan, has expressed interest in a potential return to Japanese baseball. The Nationals officially selected Kent’s contract, clearing the way for his debut against the Chicago Cubs. Kent, a former fourth-round draft ~~pick,~~ pick and prospect ranked No. 8 in the organization, enters the roster ~~as a highly-regarded prospect~~ after recording a 9-4 record and a 3.72 ERA in the minor leagues this season.
