LAS VEGAS (UNLVRebels.com) — You really had to see it to believe it. 

Last-chance heroics secured a fifth straight win to open the season as UNLV (5-0) finished play in the Rebel Kickoff tournament Saturday night.

Janyssa Martin hit a three-run blast in the bottom of the seventh inning to complete a five-run rally as UNLV defeated Hawaii 12-11 in extra innings. All five runs scored with two outs series of at-bats 

"I think we were pressing a little bit in the middle of the game," UNLV head coach Kristie Fox said. "I was just trying to keep the team calm and composed in those final at-bats.

"Early on, we had a lot of opportunities and we had too many fly outs. So our big push late in the game was less fly outs, more line drives, and the home runs will come."

The Rebels cruised past Cal State Bakersfield 9-3 in their afternoon opener. UNLV scored four runs in the first as Alyssa Trejo knocked in two with a triple and then scored on the next at-bat when Denise Armendariz smacked a home run into the scoreboard in left field.

"Our pitching staff is doing a really good job. I was really impressed with their maturity and composure when I was putting them in some tough situations. We're trying to figure out the best matchups for each of them, when to pull them, and when to let them work through things.

"And then for the team to have their backs and get them the run support that we needed to get the 'Ws' today is a really promising sign for this bunch."

Game 1: UNLV 9, Cal State Bakersfield 3
Jenny Bressler allowed one run and struck out eight in 6 ⅓ innings against the Roadrunners.

After the first-inning thumping, UNLV added two runs in the third off Jasmine Martin's double. April Visser slugged a solo shot in the fourth, then Alyssa Trejo homered to plate older sister Mia. 

CSUB ended the shut out with two runs in the fifth and Samantha Pech's solo homer in the sixth. But Bressler retired three of four batters faced in the seventh to earn the win.

Game 2: UNLV 12, Hawaii 11 (8)
UNLV took a 4-0 lead into the fifth inning before Hawaii shortstop Nawai Kaupe hit a three-run home run to put the pressure on the Rebels' defense. First baseman Dallas Millwood drove in two with her home run in the sixth and the Rainbows' bats slugged in five runs in the seventh to give Hawaii a 10-5 advantage into the final regulation frame.

But it was UNLV that claimed the pot of gold as Alyssa Trejo and Armendariz batted two-out RBI singles before Janyssa Martin rocked the Vegas skyline off a 1-0 offering.

"All I was thinking when (Denise) got the hit in front of me was, 'Please don't get out!'" Janyssa Martin jokingly recalled. "I just thought, 'Look for your pitch.Just look for it.' And I saw it—and I swung."

Kaupe batted in Hawaii's placed runner in the top of the eighth. UNLV led off with Samantha Diaz's single and Lauryn Barker's sacrifice bunt to put runners at second and third. Maddie Schmidt drove in placed runner Julia Vollmer, then Visser knocked in Diaz for the walk-off victory.
