Not finding a digital version of the 2013 Kettleers’ schedule on the team’s website, I manually made a simple one in Google Calendar.
The XML version is here: https://www.google.com/calendar/feeds/iokp41b1c1s8djcsd999ic1t40%40group.calendar.google.com/public/basic
The iCal version: https://www.google.com/calendar/ical/iokp41b1c1s8djcsd999ic1t40%40group.calendar.google.com/public/basic.ics
and the HTML version for access through any browser: https://www.google.com/calendar/embed?src=iokp41b1c1s8djcsd999ic1t40%40group.calendar.google.com&ctz=America/New_York
The official version can be found on kettleers.org here.
Opening Day is Wednesday June 12 at Lowell Park.
