LAFAYETTE – No. 16 Louisiana Ragin’ Cajuns Softball prevailed in an extra-innings battle with No. 2 Florida in the series finale of a Top 25 showcase at Lamson Park.

Pitcher Summer Ellyson tossed 11 strong innings in the circle and freshman Casidy Chaumont delivered the walk-off home run in a 4-3 win over the visiting Gators in 11 innings.

After Louisiana (7-2) evened the score at 2-all, Ellyson prevented the Gators (8-1) from placing a runner in scoring position from the fourth through ninth innings as she dueled against Aleshia Ocasio.

UF pulled ahead momentarily in the 11th inning off a two-out double. Kara Gremillion fouled off five straight pitches of a nine-pitch at bat to bring Chaumont to the plate with the go-ahead run in the bottom half. Five pitches later, on a 2-2 count, Chaumont cleared the fence in left center to bring the crowd of 2,040 into a frenzy.

Ellyson improved to 3-0 and collected her first career win over a ranked foe. She scattered eight hits over five times working through the Gators’ batting order.

The Ragin’ Cajuns, who defeated Oregon State on Thursday, closed the week with a 2-2 mark over a four-game span against teams listed in both national polls.

Alissa Dalton (2-for-5) and Gremillion (2-for-4) each had a two-hit game for Louisiana.

Dalton, who put the Cajuns on the board in the third inning with a two-run single off of Kelly Barnhill, joined Chaumont in multiple-RBI efforts.

Dalton and Chaumont led the defensive effort behind Ellyson each tallying five assists. Louisiana collected 18 assists in a clean effort in the field.
