HONOLULU — After throwing the 28th perfect game in the history of NCAA Division II baseball, Hawaii Pacific University right-hander Jack O’Brien was named the National Collegiate Baseball Writers Association NCAA D-II National Pitcher of the Week on Wednesday.

The 10-0 Sharks win in a seven-inning game against Providence Christian at Hans L’Orange Park last Friday was the first perfect game in the history of the Pacific West Conference, and the second in HPU history. O'Brien was also named PacWest Pitcher of the Week.

O’Brien, a 6-foot-4 sophomore from San Diego by way of Palomar Community College, retired all 21 batters he faced on 80 pitches in his first game as a Shark, striking out 10.

He struck out seven his first time through the Providence Christian lineup. O’Brien had to work the hardest against the last batter of the game, but got a nine-pitch strikeout.

HPU’s last perfect game came on March 8, 1999, by Ryan Evans against Christian Brothers in a seven-inning game that the then-Sea Warriors won 18-0.

HPU is the first Division II school to have two perfect games on the NCAA’s list that started in 1957.

O’Brien takes the mound first for HPU (4-0) its its next series at Hans L’Orange against Saint Martin’s beginning Friday.
