Jankowski, 23, is batting .346/.443/.413 with seven RBI and 13 steals through 27 games for Double-A San Antonio. A wrist injury marred his 2014 campaign, but Jankowski swiped 71 bags in 2013 and appears to be rounding back into form. He has also been getting on base at a high clip, drawing more walks (18) than strikeouts (14). He has virtually no power, but any player who can hit for average and swipe 50-plus bases is worth monitoring.
