Walker and Rogers, who are both playing in the Arizona Fall League, were considered locks to be added to the roster, while Dean, Chargois and Melotakis were all good bets to be added. The additions of Rosario and Landa were more surprising, as neither have pitched above Class A Cedar Rapids.
Landa, who had a 1.67 ERA with 31 strikeouts in 27 innings as a right-handed reliever for Cedar Rapids, is ranked as Minnesota's No. 30 prospect by MLBPipeline.com, while Rosario isn't ranked among the Top 30. Rosario, a left-handed starter, had a 3.52 ERA with 45 strikeouts in 53 2/3 innings at Cedar Rapids.
