Five-time Olympic medalist Missy Franklin made it official Wednesday, signing a national letter of intent to swim for the Cal women’s team starting in September.

The 17-year-old Centennial, Colo., resident plans to swim collegiately for two years and then turn pro before the 2016 Rio Olympics.

Cal coach Teri McKeever said the plan is for Franklin to earn her college degree and continue training with the Bears as part of their post-graduate ranks, which have included Olympic champs Natalie Coughlin and Dana Vollmer.

Franklin joins a Cal team that is the two-time defending NCAA champion. She was part of a recruiting class that included five other swimmers and a diver.

Franklin’s signing capped a busy week for the teenager who won four gold medals and a bronze at the London Olympics under McKeever, who was the U.S. women’s coach. Franklin swept the backstroke events in London, with her other three medals coming on relays.
