Arismendy Alcantara was signed by the Cubs as a Free Agent in November, 2008 as a 17-year-old. He's been on a very slow climb through the chain...2009 Dominican League, 2010 Rookie League (Boise), 2011 Low A (Peoria), 2012 High A (Daytona), and 2013 AA (Tennessee). We'll have to see if he follows form and hits Wrigley in 2015. A middle infielder with limited power, I'm not sure where the Cubs would have room for him on the major league roster.
Gioskar Amaya came to the Cubs in July, 2009 as a non-drafted free agent. He, too is on the slow climb, spending 2010 in the Dominican League, 2011 in the Arizona Rookie league, and 2012 in A Boise. He did get one AB in AAA last year...not sure what the story there is. This season he's with the Kane County Cougars and is hitting .253 through Sunday.
Tayler Scott has the least professional experience of the four Cubs prospects, being drafted by the Cubs in the 5th round of the 2012 draft. He spent the 2012 season in Boise and led the team in wins with a 5-1 record. He's in Kane County this year and is 2-1 in seven starts.
Tomorrow I'll have the State and Hometown cards for all eleven Cubs in the Bowman set.
