The Braves announced on Monday night that the club acquired minor league outfielder Alex Jackson and a player to be named later from the Mariners in exchange for pitchers Rob Whalen and Max Povse. The Mariners designated pitcher Ryan Weber for assignment to open roster space.
Jackson, 20, was selected by the Mariners in the first round (sixth overall) in the 2014 draft. In his second season at Single-A Clinton, Jackson hit .243/.332/.408 with 11 home runs and 55 RBI in 381 plate appearances. MLB Pipeline rated Jackson as the sixth-best prospect in the Mariners’ system.
Whalen, 22, made his major league debut this past season, making five starts. He yielded 20 runs (18 earned) on 20 hits and 12 walks with 25 strikeouts in 24 2/3 innings. He will most likely open the season with Triple-A Tacoma.
Povse, 23, split the season between High-A Carolina and Double-A Mississippi, putting up a 3.36 ERA and a 139/29 K/BB ratio in 158 innings. The right-hander could potentially open the year at Triple-A Tacoma as well.
