Conference titles races across the country are becoming clearer after this weekend, as most teams have just one or two series left to go in the regular season. Still, there is drama to be had before we reach the postseason. Here’s what went down in NCAA softball over the final weekend in April:

No. 2 Oregon sweeps No. 4 Washington in Seattle, tied with No. 1 UCLA atop Pac-12

A dramatic extra-innings grand slam by DJ Sanders in Game 1 against Washington on Friday set the table for an Oregon sweep of its conference rival in Seattle. Sanders slammed her crucial dinger off Huskies ace Taran Alvelo, who allowed just her sixth home run of the year. The 7-2 loss on Friday was Washington’s first Pac-12 defeat at home all season.

The Ducks went on to take the final two games of the series (4-2, 5-3), with Sanders adding another homer in the finale. The three wins moved Oregon into a tie for first place with UCLA in the Pac-12 at 15-3 with just two series left in the regular season. The Ducks will play last-place Utah at home this upcoming weekend.

Minnesota’s Amber Fiser tosses a perfect game against Purdue

Minnesota sophomore Amber Fiser pitched the program’s sixth-ever perfect game Saturday in a 4-0 road win over Purdue. In a game that lasted just 82 minutes, Fiser notched six strikeouts against just 15 batters as her defense picked up the slack from there.

PERFECT! Amber Fiser with her first collegiate perfect game after tossing a no-hitter exactly one month to the day. MERCY!

With a weekend sweep of the Boilermakers, the Gophers have now won 12 games in a row. They trail Michigan by a half-game in the Big Ten standings.

No. 3 Oklahoma walks off Texas to keep perfect conference season alive

The Sooners have won 35 of their last 36 games, and their latest victory required some extra-innings drama at home against Texas on Sunday. Trailing 4-3 entering the bottom of the eighth, Jocelyn Ato whacked her second dinger of the day to tie up the game.

Then Lea Wodach did this to complete the sweep over the Longhorns:

The two-time defending NCAA champions are now 44-3 and have won 27 consecutive home games. Texas has to be kicking itself for letting this one slip through its fingers.

Speaking of Oklahoma, well, how does this even happen?

During Saturday’s eventual 7-1 win over Texas, Lea Wodach worked some wicked sorcery to somehow score here. Um… what.

With this dance and her walk-off single on Sunday, Wodach had one hell of a weekend for OU.

No. 5 Florida takes series against No. 10 LSU, zeroes in on SEC title

Fifth-ranked Florida increased its lead in the SEC to two games with a 5-3 comeback victory at home against LSU on Sunday coupled with a Georgia loss. Junior Amanda Lorenz keyed the rally against the Tigers with a bases-clearing triple in the bottom of the fifth:
