10-year old Ronald Dalmacio of Rose Bowl Aquatics Swim Team broke the National Age Group Record in the boys’ 10-and-under 100 yard IM on Sunday at 2015 Far Westerns Championships in Morgan Hill, California. His 1:01.21 was exactly 10/100 faster than the previous mark, set by Michael Andrew in 2010.
Dalmacio lowered his own NAG record in the 100 back on Saturday, becoming the first 10-year-old in history to go under 59 seconds.http://swimswam.com/ronald-dalmacio-of-rose-bowl-breaks-59-in-100-back-lowers-own-10u-nag-record-at-far-westerns/
Without pads at each end of the pool we can only compare 50s. But taking a look at the two halves of the race for both Andrew and Dalmacio, we can surmise the backstroke made the difference in Dalmacio’s NAG. He and Andrew split the breast/free half nearly identically; it’s the front half where Dalmacio gets the edge.
|Michael Andrew, 2010||27.96/33.35 = 1:01.31|
|Ronald Dalmacio, April 2015||27.87/33.34 = 1:01.21|
