HOUSTON — No. 21 Oregon’s hot start to the 2020 softball season continued with a perfect weekend at the Houston Tournament.

Samaria Diaz pitched a dominant shutout and Rachel Cid belted a walk-off three-run home run to lead the Ducks to a 9-0 start to coach Melyssa Lombardi’s second season with a 9-0 victory over Dayton in a six-inning game on Sunday.

Oregon got on the board in the bottom of the second, getting a couple of runs on three hits to take a 2-0 advantage. Vallery Wong accounted for both runs, driving in Mya Felder with an RBI single for the first, then coming across to score from third when Jasmine Sievers got caught in a rundown between first and second.

The Ducks extended the lead with a pair of runs each in the fourth and fifth innings. Sievers made it 3-0 with an RBI double in the fourth to score Wong, before she came around to score on an error by the Flyers’ catcher on a squeeze bunt attempt.

Former Marist High star Ariel Carlson stretched the lead to 6-0 with her second home run of the weekend – a two-run bomb down the left field line that scored Terra McGowan.

Cid came up with runners on first and second with two outs in the bottom of the sixth and ripped a three-run opposite field bomb to end it, scoring Maddie Hopper and Haley Cruse.

Diaz got off to a bit of a rocky start by giving up a leadoff single and only getting out of the first inning unscathed when Lexi Wagner, Sievers and McGowan combined to cut down a runner at the plate on a double.

From there, though, the senior dominated, allowing just two hits over the final five innings while picking up seven of her eight strikeouts over that span.

Diaz, threw six shutout innings with eight strikeouts and no walks while giving up just four hits. The New Mexico State transfer ended the weekend 3-0 and gave up no runs over 15 innings pitched with 18 strikeouts and just two walks.

Cid went 2-for-4 with three RBIs and a run scored with a home run on Sunday. The sophomore third baseman went 7-for-15 (.467) and drove in eight runs while hitting two home runs and scoring seven runs in the four games

Sievers finished 2-for-3 with a double, RBI and a run scored. McGowan turned in a 2-for-4 day with a run scored.

Wong went 1-for-2 with a run scored and made a great defensive play on a pop up in shallow right field to save a run in the third inning. Carlson was 1-for-3 with a home run and two RBIs.

The Ducks committed their first error of the season after going the first eight games without one.

Six different Oregon players combined to hit nine home runs during the weekend, with Cid, Carlson and Felder hitting two each. The Ducks outscored their opponents 40-9 (10.0-2.3 per game).

McGowan went 6-for-12 with a home run, double, three RBIs and five runs scored. On the season, the redshirt freshman catcher is hitting .452 with four doubles, two home runs and 13 RBIs.

Felder hit .500 over the four games with a pair of bombs and four RBIs.

Oregon will return to action on Thursday at the Mary Nutter College Classic in Cathedral, Calif.
