And again, it was behind the same recipe as the other three victories this weekend, with the Sooners getting a quality start and timely hitting.
Freshman lefty Dillon Overton shined through six innings, allowing only a pair of earned runs, while striking out five and walking just two on the way to his eighth victory of the season.
In the meantime, senior right fielder Elliott Blair picked the perfect day to excel at the plate, going 2-for-3 with a triple, two RBI's and a run scored on Senior Day, and junior catcher Tyler Ogle, who had struggled some coming into Sunday, smashed a two-run bomb as part of his 2-for-4 performance with three RBI's.
Senior second baseman Cale Ellis was the third Sooner with a multi-hit outing, as he went 2-for-3 with a walk and run scored.
"We had four seniors in the lineup that all performed really well," said OU head coach Sunny Golloway. "I was really happy for Elliott Blair. He had a big day, and we needed it. He had some big hits early on. He's a guy who's trained hard. He's worked hard. He's one of our captains. We don't put guys out there just to put them out there. We feel like they can secure victory; that's why they're in the lineup."
And the bullpen, all seniors on this day, did its part as well.
Anthony Collazo, Tysen Seng and closer Ryan Duke combined for three innings of shutout ball with a pair of strikeouts and no walks.
But the Sooners bounced back in the bottom of the second when Blair singled and scored left fielder Casey Johnson.
OU added one more to make it 2-1 in the third off Ogle's first RBI of the game, a single up the middle that scored Ellis.
Then, the Sooners followed suit again in the third when Blair recorded his second RBI, this time on triple to deep right center that scored second baseman Caleb Bushyhead.
In the fifth, Ogle's homer plated Eisenberg and gave OU a comfortable 5-1 cushion.
New Mexico cut the deficit to 5-2 when left fielder Luke Campbell scored on a fielder's choice in the top of the sixth.
OU responded with one more of its own in the bottom half, when center fielder Erik Ross laid down a perfect squeeze bunt, scoring Blair.
And that capped off all the scoring.
The Sooners will take their nine-game winning streak to Waco, Texas for the final weekend of the regular season and a battle against the Baylor Bears.
Should the Sooners sweep, they will finish no worse than third in the Big 12 Conference Standings.
They are eliminated from regular season title contention but could still mathematically finish second if Texas A&M swept Texas.
