Positive: Justin Martinez now throws a sinker, and its an absolute hammer!
Justin Martinez has been a divisive player among Dbacks fans this past season. On 1 hand, you have a player who already holds the fastball velocity records for the Dbacks at just 21 Y/O last season at 102.7 MPH. On the other you have a player who has averaged over 20% BB the past 2 seasons and gives up way too much hard contact.
However something is different about Justin Martinez this season. Yes his 4.5% BB rate versus 22 spring training batters is really encouraging.
