ATLANTA (AP) — The Atlanta Braves called up top prospect Ian Anderson to make his big league debut Tuesday night against Gerrit Cole and the New York Yankees. The Braves added the 22-year-old right-hander in hopes of bolstering a rotation that has struggled to find any consistency beyond top starter Max Fried.The third overall pick in the 2016 draft, the anticipation for Anderson's arrival in Atlanta grew as he made a rapid rise in the farm system. He started the 2019 season at Double-A Mississippi, where he went 7-5 with a 2.68 ERA in 21 starts. He had 147 strikeouts in 111 innings.Moving up to Triple-A Gwinnett late last season, Anderson struggled a bit in five starts. He went 1-2 with a 6.57 ERA, surrendering five homers in 24 2/3 innings.The plan was for Anderson to spend most of this season at Gwinnett, but the coronavirus pandemic shut down the minor leagues. So he's been working at the Braves' alternate training site, awaiting his chance.Even though the Braves are leading the NL East, their rotation has been a major issue. Felix Hernandez opted out before the shorted season even began, Mike Soroka went down with a season-ending Achilles injury, and Mike Foltynewicz and Sean Newcomb were both demoted because of their poor showings. Fried (4-0, 1.32 ERA) is the only starter to earn a win, putting a heavy load on the bullpen.In addition to activating Anderson, the Braves were bolstered Tuesday by the return of outfielder Ronald Acuña Jr. from the 10-day injured list.Acuña missed the past two weeks with an injured wrist.To make room for Anderson and Acuña, the Braves optioned right-hander Touki Toussaint and third-string catcher Alex Jackson to the alternate training site at Gwinnett.Toussaint failed to take advantage of his shot at earning a spot in the rotation, going 0-1 with a 7.89 ERA over six games including four starts.___Follow Paul Newberry on Twitter www.twitter.com/pnewberry1963 ___More AP MLB: https://apnews.com/MLB and https://twitter.com/AP_Sports
