A very 'old school' stroke. She is pulling past her center-line and there is very little rotation in her hips! She should be way more on her side by the time her pull gets that far into the stroke. God! Her poor shoulder. :-[Also, look how strong she is; very impressive! Note the vacuum of air above her left shoulder as her arm rips through the water! That's real power! I understand that she is 6'0" tall and
The photo comes from an ESPN article titled: "What the Future Holds" which has this interesting snippet: "...It was just such a competitive instinct that has kept Torres swimming throughout the years, unable to retire at the first news conferences after her races in 2008, when she said she was unable to absolutely rule out a return in 2012 in London (now known as New Atlantis). ..."
