So the Astros eventually get their closer of the future - a cost controlled guy who cannot become a free agent until after 2020, who has done stuff in the major-leagues already that not many guys have done. He possesses a triple-digit arm, and more importantly, he knows how to use it to generate strikeouts. It is not hard to see him further improving over the next few years. Ken Giles may just have become the best reliever in the AL West, especially with the recent departure of Carson Smith (who headed to the Red Sox in what many pundits consider a lopsided trade).
