The teams.

Two programs, one in the DMV's independent school league and one in Montgomery County's top travel pipeline.

Sidwell Friends Quakers
School · MAC

Sidwell Friends School — Quakers

Sidwell Friends is a Quaker PK–12 day school founded in 1883, with its main campus on Wisconsin Avenue in Northwest D.C. The Quakers compete in the Mid-Atlantic Athletic Conference (MAC) for boys' sports, with maroon and gray as school colors and a fox as the spirit mark.

The baseball program is led by Head Varsity Coach Jon Mormino, who has coached at Sidwell across the 7/8, JV, and Varsity levels since 2002. In 2025, the Quakers went 14–6, won the MAC regular-season banner for the first time since 2008, and recorded their most regular-season wins since 2011 — a step-change for a program that had logged just two winning seasons in the prior decade.

Moco Shockers
Travel · 13u

Shockers Baseball MoCo — 13u

Shockers Baseball MoCo is a 501(c)(3) nonprofit travel program based in Montgomery County, Maryland, founded in 2019 to give Montgomery County Little League players a path to compete at a higher level while keeping the culture and camaraderie of Little League intact.

The program fields teams from a 7u developmental squad up through 13u, and has quickly established itself as one of the top travel organizations in Montgomery County in the age groups it competes — with its 13u squad currently listed among the ranked 13u programs in Maryland by Travel Baseball Rankings.
