After losing their opening game in the American Legion Western Regional Tournament being played in Denver, the Petaluma Leghorns began battling back Thursday, beating Pleasant Grove, the Utah state champion, 5-2.

The Leghorns, the California state champions, dropped their opening game on Wednesday to Las Vegas, the Nevada state champion, 3-2. The early loss puts the Leghorns in the difficult position of having to play — and win — every day through the end of the tournament on Sunday as they strive to survive in the double-elimination tournament, the final step en route to the American Legion World Series in Shelby, N.C.

Petaluma plays today against Fort Collins, the Colorado state champion.
