There is no need to pre-register your player for Bison tryouts. Simply attend the specific age level tryout, giving yourself enough time prior to the actual tryout to warm up and register at the field. Players need only attend one tryout.
Age Guidelines (player's age on April 30th, of playing season):
14U - 14 year old and 13 year old, 8th graders
13U - 13 year old, 7th & 8th graders
12U - 12 year old and 11 year old, 6th graders
11U - 11 year old and 10 year old, 5th graders
10U - 10 year old and 9 year old, 4th graders
9U - 8 and 9 year olds
Please Note: The above age guidelines are just that, simply recommendations but not hard rules. From past experience, DBOB strongly recommends that 12 year old and younger players participate with their age group and 13 year old and older players participate with their grade. However, we will assume a player's intention by the tryout they show up to. For example, an 11 year old (any grade) that only attends the 11U tryout will only be considered for the 11U team. Yet, an 11 year old that attends the 12U tryout, will be considered for the 12U team, but will also be considered for the 11U team if they don't make the top 12U team.
Note2: Please notice that the tournament baseball (USSSA, CABA, TCS) age cutoff date is different from Little League. NBLL/SBLL use October 31st to identify a player's age for that summer. Tournament baseball organizations use April 30th to determine a player's age for that season. The Boulder Bison use the tournament baseball rules for eligibility.
