Atlanta acquired Thomas and left-hander Bailey Falter from Kansas City on Saturday in exchange for left-hander Carter Holton and right-hander Lucas Braun, Jeff Passan of ESPN.com reports.
Thomas was removed ahead of the fourth inning of the Royals' game against the Rockies on Saturday, and Passan's report came out a short while later indicating that the veteran outfielder was dealt for the second time in the last three trade deadlines. Though he had been serving as the Royals' primary center fielder since Kyle Isbel (foot) landed on the 10-day injured list in early June, Thomas will likely serve as a fourth outfielder in Atlanta, with most of his opportunities likely to come against right-hander pitching. Thomas entered Saturday with a .230/.325/.392 slash line with 10 home runs and seven stolen bases across 326 plate appearances this season.
