Coach Ma works her magic down Mexico way

Mexican world champion diver Paola Espinosa leapt off the 10m platform during a practice session in Rio.

As she did so, a 40-something woman with black curly hair stood out from the Mexican's coaching crew, focusing hard on Espinosa's multi-twist routine.

She kept her eyes glued to the diver's descending curve, clapping hard and chanting "bravo" every time Espinosa knifed into the water with minimal splash.
