WALLA WALLA, Wash.  The opening rounds of singles went off like clockwork in the chilly but sunny morning on Saturday, with Whitman's entrants enjoying much success. Second-round results and ensuing doubles results matched the sunny outlook for the Blues, too, as Day 1 of the ITA/Oracle Northwest Women's Tennis Regional enters the night.

Five of seven Blues captured first-round singles matches with four of those five rolling past second-round opponents.

Many of those Whitman wins were in dominating fashion.

Hanna Greenberg opened Saturday with a 6-0, 6-0 victory, then pushed her way into Sunday with a 6-2, 6-1 second-round win.

Andrea Gu -- the 2017 Northwest Conference freshman of the year -- won just as commandingly, taking her two matches by identical counts of 6-3 and 6-1.

First-year Anastasiya Redkina laid claim to even more resounding victories, opening with a 1 and 1 win, followed by a second-round victory without surrendering one game.

In one of the first matches Saturday, Whitman's Lori Sheng had to rally from a 7-6 opening-set tie-break loss, eventually capturing the second set, 6-3, and super-tiebreak third set, 1-0 (10-4). Apparently sufficiently warmed up, she rolled through a 3 and 1 win in the second to move into Sunday's morning rounds.

Another first-year, Kattie Pak, won her opening set but was pushed into the consolation bracket after dropping her second-round match.

The Blues' Jenna Gilbert and Lorin DeMuth  lost opening–round matches to a pair of seeded players.

All three of Whitman's doubles pairings moved into the second round with solid victories.

The No. 3 seeded duo of Gu and Greenberg downed a pair from Willamette by an 8-4 count, while Sheng and Gilbert won 8-2 over a Linfield pair. The all-first-year teaming of Pak and Redkina looked fantastic in their 8-0 rout of a George Fox pair, and then won out over a team from Willamette to advance into Sunday's third round.

Regional action continues Sunday with singles matches kicking off the morning at 9 a.m., followed by quarterfinal matches tentatively scheduled for noon. The quarterfinal round of the main doubles draw hits the courts after the conclusion of those last singles battles.

The semifinal singles match is scheduled for Monday at 9 a.m., with the championship match to follow one hour after the conclusion of the longest of those two semis.

The semifinals of the doubles main draw finishes off the Sunday matches, with the doubles championship playing after the singles championship match on Monday.
