DUTCHTOWN — It was a fitting way for senior LaShone Redditt to walk off her home floor one last time.

Redditt scored eight of her game-high 22 points in the final quarter and came up with a key block, enabling Dutchtown to secure a 52-49 District 5-5A win Monday over St. Joseph’s Academy.

“The seniors had to step it up a notch and give it all we had,” Redditt said. “That was a big win for us.”

Dutchtown (18-12, 7-2) kept its postseason hopes going after entering the game with an unofficial power rating of No. 36 — four below the cut-off.

The Lady Griffins have to close the regular season Thursday with a win over East Ascension and need SJA (15-11, 8-1) to falter at McKinley a day later to share the league championship.

“It is what it is,” Dutchtown coach Annette Lowery said of her team’s postseason prospects. “It would be great. I’m hoping we can get there, but we have one more game.”

Dutchtown began cutting into SJA’s 11-point, third-quarter lead with a 10-2 run over the first two minutes of the fourth quarter, pulling within 37-36 on Tyler Smith’s steal and layup.

The Lady Griffins, who trailed for all but 20 seconds, took their first lead with 2:50 remaining on a 3-pointer from Kelsie Baker following a turnover. That touched off a scintillating next minute, featuring four lead changes and a tie at 47 with 1:48 left on Redditt’s basket.

Olivia Abadie made both of SJA’s field goals in the last 2 minutes, the latter coming on a pull-up jumper against full-court pressure for a 49-47 lead with 49 seconds left.

Baker, who has been hobbled by an ankle injury and didn’t start, took on a bigger scoring role with 17 points after starting point guard Kyra Harleaux exited in the third quarter with an apparent broken nose.

Dutchtown took the lead for good at 50-49 with 21 seconds left on Baker’s second 3-pointer of the quarter and relied on Redditt’s heroics to make it stand up.

After a missed layup, SJA retained possession under its goal and, following timeouts by both teams, Abadie, who scored 15, had her 10-footer blocked by Redditt from the baseline with 2 seconds to go.

Caroline Olivier led the Redstickers with 17 points but was held scoreless over the final 9 minutes.

“I think it came down to them making more shots than we did,” SJA coach deLynn Stelly said. “(Baker) hit a couple of huge 3s, and (Redditt) stepped up her game.”
