Alex Merrill won the 200 and 500 free.

LA JOLLA, Calif. -- The UC San Diego men's and women's teams swept nationally-ranked foes in dominating fashion at Canyonview Pool on Friday.

The fifth-ranked Triton men (3-2) defeated No. 2 Incarnate Word (0-2) 179-78 and topped eighth-ranked Missouri S&T (5-2) 153.5-102.5, while the third-ranked UCSD women (4-2) beat No. 4 Incarnate Word (0-1) by a score of 144-106. Missouri S&T got past Incarnate Word 151-110 in the other men's competition.

UCSD swimmers produced the top marks in 21 of the 28 combined events during the three-hour meet.

Junior teammates Nicholas Korth and Alex Merrill were the two Tritons on the men's side to touch first in multiple individual events. Korth swept the breaststroke distances in 56.71 and 2:03.22. Merrill was fastest in the 200 free (1:44.47) and the 500 free (4:42.01), just getting his hand to the wall before Incarnate Word's Mark Rubin (4:42.14) in the 500. Merrill also anchored the opening 400 medley relay (3:26.92), with Korth swimming the second leg, and led off the fastest group in the meet-ending 800 freestyle relay (7:01.40).

The Triton women were led by their two co-captains, senior Beth Dong and junior Anji Shakya. Each turned in the top times in a pair of individual events, while both also were part of the fastest 800 free relay and second-best 400 medley relay foursomes.

Dong, who has now won two events in three consecutive meets to begin 2013, outdistanced the field in the 200 back (2:07.58) and her specialty, the 400 IM (4:31.62). Shakya beat her counterparts in the 200 free (1:55.09) and 500 free (5:04.05). They were joined by Naomi Thomas and Dari Watkins in the 800 free relay (7:47.88).

Freshman Rosa Bebi swept the breaststroke events, racing 1:07.71 in the 100 and 2:25.91 in the 200. Bebi was second-fastest after Dong in the 400 IM (4:40.54).

Freshman Paul Li swam 16:06.23 in the 1,650 free to take down Rubin, a two-time All-American in the distance events at the 2012 DII championships, by more than five and a half seconds. He also touched second in the 400 IM in 4:13.57, just ahead of junior teammate John Chang in third (4:13.77).

Remaining individual winners for the UCSD men were senior co-captain Julius Espiritu (100 back, 53.59), Dane Stassi (200 fly, 1:53.40) and Alex Moshensky (200 back, 1:56.70).

The women got first-place swims from Erika Rodman in the mile (17:29.02), Sandy Hon (100 back, 1:00.84), Thomas (200 fly, 2:08.62) and Jaclyn Amog (100 fly, 58.88). Hon was also second in the 200 (2:09.98) behind Dong.

The Tritons swept the top-three spots in five events on the day. Merrill led in freshman Michael Leung (1:45.39) and John Chang (1:46.91) in the 200 free. AJ Zavala (58.94) and Jacob Lammott (1:00.02) followed Korth in the 100 breast. Moshensky, Luke Mitchell (1:58.70) and Paul Guzman (2:00.41) went 1-2-3 in the 200 back, with Shakya, Rodman (5:09.03) and Watkins (5:14.97) doing the same in the 500. Megan Lee (4:41.26) was behind Dong and Bebi in the 400 IM. UCSD swimmers went 1-2 in six other events.

Stassi and senior Adam Yen joined Korth and Merrill on the first-place 400 medley relay. Leung, Espiritu and Li were in the water after Merrill in the 800 free relay.

In the 200 fly, Stassi trailed Missouri S&T's Andy Schranck, the winner of the 100 fly (51.03), by .79 seconds after 50 yards, but used a blistering next 50 (28.38 to 29.39) to pull away and hit the pads first by over two full seconds.

Incarnate Word senior Tamiris Nascimento swept the women's sprint freestyle events in 24.05 and 52.98 after anchoring the first-place 400 medley relay (3:38.32).
