Davis, Calif. - UC Davis matched serve with Hawai'i for five innings on Sunday but fell 1-17 in the series rubber match.
Carson Seeman threw two scoreless innings as the opener and
Bryan Green pitched a shutout over the next three before Hawai'i struck for four runs in the sixth.
UC Davis (4-22, 3-15) got one back on
Nathan Peng's home run in the bottom of the seventh but the Rainbow Warriors added on with a four-run eighth and a nine-run ninth inning.
Peng capped a weekend in which he threw two hitless innings as the opener on Friday, went 3-3 as the designated hitter on Saturday and 2-4 with the home run as the catcher on Sunday.
Mark Wolbert extended his hitting streak to 13 games by legging out ball hit to the right side in the eighth.
The Aggies have a tight turnaround hosting San Jose State on Tuesday but will not play again afterwards until traveling to Stanford on May 3.
