Palka was the club's No. 22 overall prospect by MLBPipeline.com, while Rosario and Goodrum both made their Major League debuts in 2017.
Rosario, 23, is a hard-throwing lefty who struggled in his first taste of the Majors, allowing eight runs on seven hits over 2 1/3 innings. He posted a 4.08 ERA with 45 strikeouts and 23 walks in 57 1/3 innings at Double-A Chattanooga last season. It was his first full season pitching in relief. He has a career 3.37 ERA with 289 strikeouts in 352 1/3 innings in the Minors.
Palka, 26, is a left-handed-hitting slugger who batted .274/.329/.431 with 11 homers and 13 doubles at Triple-A Rochester last year. He hit a combined 34 homers between Double-A and Triple-A in 2016.
Goodrum, Minnesota's second-round pick in 2010, made his Major League debut in September after eight years in the Minors. He hit .265/.309/.425 with 13 homers and 66 RBIs while mostly splitting time between shortstop and right field at Triple-A in 2017. Goodrum went 1-for-17 in 11 games with the Twins.
