OKLAHOMA CITY, Oklahoma, December 22. DURING time trials yesterday at the Chesapeake Elite Pro-Am, 14-year-old professional swimmer Michael Andrew broke another 13-14 U.S. National Age Group record.

Andrew clocked a 44.73 in the 100-yard freestyle event. He split the swim 21.41, 23.32 en route to taking down Ryan Hoffer's record of 44.81 set for the Scottsdale Aquatic Club earlier this year.

With the effort, Andrew now holds all four of the 100-yard NAGS in the 13-14 age division. He has a 48.68 in the 100-yard back, a 55.43 in the 100-yard breast and a 47.47 in the 100-yard fly. There's no indication, however, that he's focusing on anything but sprints at this time, so a challenge to Curtis Ogren's 2010 400 IM mark of 3:54.23 may not be in the future this year.

Andrew dominated the 11-12 age division, with records in the 50 free (21.85), 100 free (47.95), 50 breast (27.46), 50 fly (23.65) and 100 IM (53.86) still in the books.

Andrew has posted a few other times in Oklahoma this weekend. He finished seventh in the 100 fly (48.16), and sixth in the 50 free (20.16). He also clocked a 45.71 in the 100-yard free prelims so far.
