Does retrosheet cover 2013-2014-2015

Appears it is 1950-2012..

Anyone that has the current year MLB subscription, we will activate the previous years on request as well to fill in the gap from 2013 and forward. Retrosheet data goes through 2012 as noted. Just send the request to support@iscoresports.com and indicate that you have the current year subscription, include your customer ID so we can confirm the current year purchase, and request that you would like the previous years added to your account as well.
