ATLANTA (AP) — They’ve known each other since they were kids, drawn together at the basketball court.

Now, LSU’s homegrown Tigers are heading to the Final Four together.

Glen Davis scored 26 points, including a decisive 3-pointer in overtime, and Tyrus Thomas added 21 points and 13 rebounds Saturday, leading LSU to its first Final Four since 1986 with a 70-60 victory over Texas in the Atlanta Regional final.

When the horn sounded, Davis marched to the front of the scorer’s table, faced the gold-and-purple-clad contingent and saluted. Then he let out a huge scream, pounded his massive chest and was mobbed by Thomas, who was named the region’s most outstanding player.

The portly Davis answers to the nickname ‘‘Big Baby’’ — which is only appropriate for this group. LSU’s lineup features three freshmen, including Thomas, and the sophomore Davis. Darrel Mitchell is the lone senior among the starters.

Three of those guys are from Baton Rouge, practically in the shadows of the LSU campus. Another grew up in nearby Denham Springs, and Mitchell is from right down the road in St. Martinsville.

‘‘We’re like brothers,’’ Mitchell said. ‘‘Brotherhood and togetherness.’’

They’ll get together again in Indianapolis, facing either Memphis or UCLA next Saturday in the national semifinals.
