Due to the success of its high school sports teams, (despite the small size of the village and school in relation to surrounding towns) East Rochester has been affectionately referred to as "The Home of Champions." Its high school men's basketball, football and wrestling teams each won numerous sectional championships from the 1960s until the early 1990s. The majority of these football and wrestling squads found their success under the direction of local legend Don Quinn. In recent years, the school's women's sports teams have carried on this tradition as field hockey and lacrosse have enjoyed dominance on both the regional and state-wide level. Interestingly enough, it is Quinn's daughter who coaches these teams.Also one of the most successful teams in East Rochester is the varsity cheerleading squad. With 6 national champion titles and 9 section five champion titles, as well as various titles from local competitions, this team has become a legend.
Baseball has always been an integral part of village life. In 1966, the East Rochester Little League's Senior Division Baseball allstar team became world champions, winning the World Series, which was held in Des Moines, Iowa.
The Bombers were the first High School in the Rochester area to play its outdoor sports upon a FieldTurf artificial playing surface, with one being installed in 2001. Until the early 1990s, the Bomber football team played an annual game with their rivals from Fairport; the Red Raiders. The winner of this game took home the coveted Little Brown Jug and was played until the enrollment of Fairport High grew much too large to make such a contest feasible. The rivalry, however, is still somewhat understood between the two neighbors as it is often referred to in other capacities outside of athletics.
The double-tracked CSX Transportation Rochester Subdivision rail line runs east-west through East Rochester, dividing the town in half. No grade crossings exist within the East Rochester limits. Two streets, NY 153 and South Lincoln Road, pass under the mainline by way of underpasses roughly 0.5 miles apart.
To better showcase the village's proximity to the city of Rochester, the village was incorporated as the Village of East Rochester in 1906.
On 16 January 2007, a 13-car CSX intermodal train traveling 60 miles per hour and carrying retail goods partially derailed at the South Lincoln underpass, spilling at least five containers and two intermodal wells onto the road below. The wreckage extended west from South Lincoln along East Maple Avenue to Madison Street as derailed cars crushed a number of vehicles parked alongside the tracks and dumped intermodal containers into the front yards of residents on Maple. Overall, eight wells and 15 to 20 containers came off the rails. As in 1969, no one was injured in the accident. The presence of mangled intermodal cars in the southbound lanes of Lincoln Road, as well as one teetering on the edge of the bridge, forced the closure of the road. It reopened January 18 following two days of cleanup. The 200 block of East Maple Avenue, however, remained closed for repair work for several days afterward.
