Marquez, 21, has a 2.63 ERA and 98:25 K:BB through 106 innings for Double-A Hartford.
Marquez has shown better command of his three-pitch arsenal this season, resulting in a slight bump in his strikeout rate as compared to 2015. In fact, he is second in the Eastern League in strikeouts. Marquez has given up nine home runs in 2016, though, which is certainly a red flag when considering where he will play his future home games.
