The Padres announced that they have designated right-hander Keyvius Sampson for assignment in order to clear space on the 40-man roster for the newly acquired Shawn Kelley.
The 23-year-old Sampson was San Diego’s fourth-round pick in 2009 and ranked among the club’s Top 30 prospects in each of the past five offseasons, per Baseball America. However, Sampson struggled mightily in 2014, working to a 6.68 ERA with 9.2 K/9 and 6.7 BB/9 in 91 2/3 innings between the rotation and bullpen at Triple-A El Paso.
As recently as last offseason, BA noted that Sampson sat 93 to 95 mph with his fastball and had scrapped a below-average curveball for a more effective slider. Those two pitches paired with a “quality changeup,” per BA, though their scouting report noted that his below-average command could be an obstacle, and that was clearly the case in 2014.
