The Cubs have added a couple of 25-year old "suspects" to Minor League Camp, acquiring 1B Matt Scioscia from the Los Angeles Angels in exchange for 1B-OF Trevor Gretzky, and signing RHP Reinier Roibal (ex-SF).
The 6'3 230 Roibal was a high-profile Cuban defector signed by the Giants in 2010, but he was unable to work his way out of Lo-A ball after three seasons in the Giants organization, and was released at the end of Minor League Camp this time a year ago. He then spent the 2013 season pitching for the Newark Bears in the independent Atlantic League.
The son of Angels manager Mike Scioscia, the right-handed hitting Matt Scioscia was selected by the Angels in the 45th round of the 2011 draft as a college senior out of the University of Notre Dame, where he had been a catcher, first-baseman, and DH. The Angels moved him to 1B full-time in 2013, but like Roibal, the younger Scioscia has been unable to progress, hitting a combined 194/248/224 in 46 games (146 PA) between AZL Angels, Burlington, and Inland Empire in 2013.
I strongly suspect the Cubs will immediately move Scioscia back to catcher, the one position in the Cubs system that lacks quality depth, perhaps hoping that his catching "bloodlines" might awaken. The Cubs are also probably hoping a change of scenery might help the younger Scioscia fulfill his promise, but at age 25 he won't have a lot of time to show what he can do.
21-year old Trevor Gretzky is (of course) the son of hockey legend Wayne Gretzky, and was the Cubs 7th round pick in the 2011 June draft. But through no fault of his own, he was seemingly buried in a Cubs system that is chock full of outfielders with promise. The younger Gretzky never fully recovered from right shoulder surgery (he suffered a torn labrum while playing QB in a football game his senior year in HS) and so he been has been relegated to playing only DH, LF, or 1B in pro ball. (He has what is sometimes called a "rag arm"). However, he doesn't have the HR power you would want out of DH, 1B, or LF, he has just average speed so he doesn't profile as a CF, and he is a below average defender at both 1B and LF. What the younger Gretzky does have is decent eye/hand coordination, a good eye for the strike zone, and a nice opposite-field line-drive stroke at the plate (albeit without any HR power).
