Remember, the Padres parted with some talented prospects in order to land several of the players they added this winter, though they were still able to retain their top prospects.
RHP Matt Wisler: Wisler, rated as the Padres' No. 2 prospect, could push for a starting job at the back end of the rotation with a strong performance this spring. He began last season in Double-A and advanced to the hitter-friendly Triple-A Pacific Coast League where he took some lumps as a 21-year-old. The Padres believe in his stuff and his makeup, but with the recent addition of James Shields, the team doesn't have a whole lot of openings.
OF Rymer Liriano: After hitting .291/.362/.473 at two Minor League stops, Liriano made his big league debut late last season and got a chance to play on an everyday basis for a spell. He looked overmatched at times, striking out 39 times in 109 at-bats. He also showed some raw power and a plus-arm in the outfield. But with the additions of Wil Myers, Justin Upton and Matt Kemp, he's likely headed back to Triple-A for more seasoning. He's rated as the team's fifth-best prospect by MLB.com.
RHP Casey Kelly: Kelly, the team's sixth-best prospect, was limited to 20 1/3 innings a year ago as he recovered from Tommy John surgery in 2013. His rehabilitation program was halted in May after he felt soreness in the elbow. The good news is that Kelly is only 25. But he needs innings at this point and those will likely come in the Minor Leagues in 2015.
C Austin Hedges: Hedges certainly had a tough year offensively in the Texas League, producing a .225/.268/.321 line, though his defense -- his calling card -- continued to shine. He's regarded as one of the top -- if not the top -- defensive catchers in the Minor Leagues and that he could catch right now in the Major Leagues. There's a sense his bat will catch up at some point and he's still young. He's rated as the team's top prospect.
OF Hunter Renfroe: Renfroe, the team's first-round pick in the 2013 First-Year Player Draft and the team's No. 3 prospect, tore through the Cal League but struggled after a promotion to the Texas League. He could begin back in Double-A again, but the thinking is he might not be there long. He's got raw power, can run, has a strong arm and a big upside. He'll be in big league camp this spring with Wisler and Hedges.
