Tryouts- 14U Vipers Summer Elite and Green Teams @ Curt Flood Field
Apr 27 @ 1:00 pm

Registration Form Tryouts for the Summer 2019 14U Elite and 14U Green teams will be held on Saturday April 27, 2019, at 1 p.m., at CURT FLOOD FIELD.  Players should be ready to go immediately at 1:00 p.m.; therefore, they should arrive suitably early to warm-up, stretch, and warm-up a bit to pitch if trying out as a pitcher.  (We will provide extra warm-up time for pitchers.)  Accordingly, we recommend arriving by no later than 12:30 — but warm-ups are ON YOUR OWN. In 2019 we expect to have two teams — the “Elite” team coached by Jonathan Klein, and the “14U Green” team coached by Maya Juergens-Ingle.  Neither head coach has a child in the program. Jonathan has been coaching Vipers for approximately 8 years, from 10U through 18U, and has coached 3 years of varsity softball at Piedmont High School. Maya was a varsity softball player at Skyline High School, and has herself been coaching Vipers for approximately the last 5 years.  Each team is expected to have a highly experienced coaching staff, with Jennifer Deering, former National Champion at the University of California, also offering pitching instruction to all interested pitchers and assistant coaching to the Elite team. The Vipers program has demonstrated great success in recent years, winning tournaments in all levels, and offers high level, competitive play in a fun environment. The Elite team will finish its summer with competition in the Western Regional Championships in Redding, CA July 21-28.  They begin play Memorial Day Weekend in Burlingame and expect to play 6-7 total tournaments in the summer; the 14U Green team will play 4-5 summer tournaments around the Bay Area. Please submit the an application form to Jonathan Klein, in advance of tryouts if at all possible, at jaklein@khiplaw.com. Feel free to email any questions to Jonathan or Maya as well.  Maya’s email is mayaji13@gmail.com
