12-year-old Ronald Dalmacio added a second 11-12 National Age Group (NAG) record for the weekend, going 1:53.33 to sneak under the 200 yard back NAG.
Competing for Rose Bowl Aquatics, Dalmacio shaved three hundredths of a second off the old record. That came just one day after he cut almost half a second off the 11-12 NAG in the 100 back. Dalmacio also holds the long course meter 50 back NAG in the age group along with both the 50 and 100 meter back NAGs in the 10&under class.
The 200 back record Dalmacio broke Sunday was previously held by Tyler Lu out of KING Aquatic Club. Lu swam to a 1:53.36 back in February of this year. The record has continued to shave down by small margins – Lu took .06 off the previous record held by Destin Lasco and Dalmacio just took .03 off of it this weekend.
A look at the splits between the previous records held by Lu and Lasco:
| Dalmacio ’16 | Lu ’16 | Lasco ’14 | |
| 1st 50 | 27.20 | 26.90 | 26.73 |
| 2nd 50 | 29.26 | 28.67 | 29.02 |
| 3rd 50 | 28.68 | 29.15 | 29.15 |
| 4th 50 | 28.19 | 28.64 | 28.52 |
| Final Time | 1:53.33 | 1:53.36 | 1:53.42 |
Dalmacio did his best work in the back half, coming up with the fastest 3rd and 4th splits of the three. Interestingly enough, the record has gotten progressively slower over the opening 50, with the record-breakers pacing themselves earlier to bring about a bigger back half.
Full results of the Kevin B. Perry Senior Invite (where Dalmacio broke the record) are available on Meet Mobile.
I would love to see a video of this guy!

56.46 – 56.87 splitting — for a 12 yr old! amazing
Agreed, but when your going a 50.99 for a 100 back, a 56.4 1st 100 split is very conservative
