OKLAHOMA CITY » Since their season was suddenly on the line, Kelsi Dunne and the Crimson Tide have made it impossible for their opponents to get them down.

Dunne pitched six spotless innings Friday night, Whitney Larsen and Kaila Hunt had RBI singles and second-seeded Alabama moved into the Women’s College World Series semifinals with a 3-0 victory over Baylor.

Top-seeded Arizona State also made it to the semis, beating Florida 6-5 on Annie Lockwood’s bases-loaded, infield single in the bottom of the seventh.

The Crimson Tide and Sun Devils each need just one win in two chances Sunday to reach the best-of-three championship series.

The tandem of Dunne and freshman Jackie Traina has put up zeroes for 30 1⁄3 innings since the third inning of a 5-2 loss to Stanford in their super regional opener.

Dunne said Larsen, a fellow senior, pulled the team together after that loss — which made it necessary for Alabama (53-9) to win back-to-back elimination games to reach the World Series — and told players to take a "fearless" mindset.

"Ever since then, we have come out and we’ve been fearless and we have fought together," said Dunne, who has 24 2⁄3 scoreless innings in a row. "We’ve just been playing. All cylinders of our game have been clicking together and coming together at the right time.

"Our defense has been phenomenal and we’ve been getting those timely hits that we have fallen short of before."

The Crimson Tide is trying to get to the championship round for the first time. It’s also the first time Alabama has been in such a favorable position. In its last two trips to the World Series, the Tide rallied back for two wins in the losers’ bracket but still needed two more to reach the finals.

Dunne (29-4) had given up 21 runs in 40 2⁄3 innings over six starts in those trips as a freshman and sophomore, then the top-seeded Tide got bounced by Hawaii in the super regionals last season when Dunne won her first SEC pitcher of the year honor.

She has allowed only five singles over 12 shutout innings at this year’s World Series.

"Kelsi is in a zone right now," coach Patrick Murphy said. "It just warms my heart to know that a senior is in that position when she comes to her final performance in her career."

Amanda Locke drove in the first run for Alabama with a sacrifice fly in the first inning off of Whitney Canion (30-11). Hunt singled and scored on Larsen’s two-out base hit in the fourth and then provided her own RBI single with two outs in the fifth.

Baylor (46-14) faces one of two Big 12 rivals, Oklahoma or Missouri, and Florida (53-11) will play either Oklahoma State or California in elimination games today.
