12-year-old Ronald Dalmacio of Rose Bowl Aquatics had an outstanding weekend at the Southern California JO’s, the highlight being his performance in the 50 back final. After going 24-low leading off his team’s 200 medley relay and then doing so again in prelims, Dalmacio unleashed a 23.65, destroying his old best time which happens to be the 11-12 NAG record.
Dalmacio’s old record was a 24.11– he lowered that by nearly half a second. With that swim, he also becomes the youngest swimmer ever, at just 12 years old, to break the 24-second barrier in the 50 back.
He also swam the 50, 100, and 200 free along with the 100 and 200 back last weekend at JO’s. He holds the 11-12 NAG records in both the 100 and 200 backstrokes, and was just off his bests in both races, going 51.42 in the 100 and 1:52.94 in the 200.
In the freestyles, he went 21.86 in the 50, 48.28 in the 100, and 1:46.17 in the 200. That moves Dalmacio up to #3 in the 50 free (just .01 behind #2 Michael Andrew and .08 behind #1 Vinny Marciano), #4 in the 100 free, and #3 in the 200 free all-time for the 11-12 age group.
Dalmacio also anchored Rose Bowl’s 11-12 200 free relay with a 21.63 as well as their 400 free relay with a 48.09.
