Braves’ prized prospect takes a tumble at first

Prized rookie Ronald Acuna Jr. took a high-flying tumble while beating out an infield hit, exiting with knee and lower back pain Sunday as the Atlanta Braves beat the Boston Red Sox 7-1.

Acuna waved his arms “safe” as he crossed the first base bag before his left foot gave out in the seventh inning, and he went sprawling. He walked off the field slowly, passing on a wheel chair that was rolled out for him.

The 20-year-old outfielder also walked and scored a run before leaving.

Welcome home

Greg Allen had one thought as he saw his teammates waiting for him at home plate.

“Just don’t get too roughed up in there,” he said. “It’s something I’ll remember forever. It’s all still sinking in. It’s pretty special.”

Allen homered on Brad Peacock’s first pitch in the 14th inning, and the Cleveland Indians stunned the Houston Astros 10-9.

Allen’s first homer of the season landed in the seats in right and triggered a wild celebration for the Indians, who rallied twice to overcome another impressive performance for Jose Altuve.

Cleveland scored five runs in the ninth. Michael Brantley’s two-out RBI single off Hector Rondon tied it at 8.

Betts takes night off

Red Sox right fielder Mookie Betts was a late scratch with left side tightness for Sunday’s game against the Atlanta Braves at Fenway Park.

Betts entered the day leading the major leagues with a .359 average and was tied in homers with the Angels’ Mike Trout with 17. Betts also has 37 RBIs.

With Betts out, Boston manager Alex Cora moved Andrew Benintendi to the leadoff spot and shifted him from left to center. He moved Jackie Bradley Jr. from center to right.
