LA JOLLA, Calif. -- Second-ranked UC San Diego split a pair of dual meets against NCAA Division I opponents on Saturday at the Canyonview Aquatic Center.

UCSD (4-3) downed Grand Canyon (2-8), in its first year reclassifying up into Division I, 181-111 but fell to Mountain West Conference power Boise State (4-4) 238-61. The Broncos also cruised past GCU 232.50-60.5.

With the Tritons already having faced San Diego State (7-0) on the road on Monday, the Aztecs were only scored against Grand Canyon (235-58) and Boise State (155-144), getting past both. The latter match-up, between the past two Mountain West champions, was the tightest affair of the afternoon. Coming out of the second and final break of the day with two events to go, the reigning champion Aztecs trailed the 2012 MW winner Broncos 137-126. SDSU went 1-2-3 in the 200 individual medley to go ahead 142-140 and hung on with a 1-3 finish in the 400 free relay.

For UCSD, senior captain Anji Shakya (1:51.54) narrowly out-touched SDSU standout Mikaela Macklin (1:51.94) for second place behind Boise State freshman Felicity Cann (1:49.54) in the 200 free. She was also fourth in the 500 free (5:04.52) and fifth (2:07.66) in the 200 back. Macklin would later win the 200 breast (2:20.01) and 200 individual medley (2:03.56).
