PASCO, Wash. — Five days removed from being one-hit in its Cascade Conference opener, the No. 3 Southern Oregon softball team unloaded on Providence (Mont.) with back-to-back 18-4 wins Friday on a record-setting afternoon at the Pasco Sporting Complex.

The Raiders (17-7, 3-2 CCC) hadn't scored 18 in one game, much less two, since 1978. Their previous runs record in a CCC contest was 17, established in 2007 against Corban.

They did it with 34 hits in the doubleheader, including 10 for extra bases. Six different players recorded at least four hits. Five scored at least four times.

The litany of offense started with senior catcher Harlee Donovan, who went 5-for-5 with five walks, six runs and four RBIs. She stroked four hits in Game 1 with a two-run home run — her third of the season — that put the Raiders up 5-0 in the second, a triple, and an RBI single. The floodgates opened when SOU scored 10 times in the sixth to trigger the mercy rule, coupling seven hits with three Argos errors.

Rebecca Velasquez added to the middle-of-the-lineup pop by going 5-for-10 with six runs and four RBIs, hitting two doubles in Game 1. Kelsey Randall also went 5-for-10 with two runs, three RBIs and a triple. Karlee Coughlin (7 RBIs, 1 run, double), Davalin Ontiveros (4 runs, 4 RBIs, double) andHannah Shimek (4 RBIs, 3 runs) had four hits apiece.

It didn't end there: Katrina Winterburn went 3-for-7 with a triple, three walks, five runs and two RBIs on the day, Hannah Wessel doubled and scored four times, and in Game 1 Taelor Mayben hit a run-scoring double and a run-scoring single and with one run scored.

The Argos, who will line up against the Raiders twice more today starting at 11 a.m., dropped to 2-4. They were originally scheduled to host the series in Great Falls, Mont., but snow forced the move to a neutral site.

The late innings were similarly unkind to them in Game 2, when they gave up three in the fifth, four in the sixth and seven in the seventh. SOU didn't untie it until the fifth, as Coughlin and Ontiveros hit back-to-back RBI singles and Mayben launched a sacrifice fly to open up what had been a 4-4 game. Winterburn's two-run triple and Coughlin's RBI double highlighted the lengthy seventh.

Relievers were credited with both of SOU's decisions: Morgan Jones (4-2) pitched 3 1/3 scoreless while allowing five hits in Game 1, and Allie Hancock (2-0) went the final 4 2/3 while allowing two hits and one run with four strikeouts in Game 2.

SOU committed one error on the day. The Argos had nine.
