USA edges Australia in softball thriller

TOKYO — In a scoreless extra-inning contest, Monica Abbott surrendered a bases- loaded walk in the top of the eighth, marking the first time an opponent scored against the U.S. in four games during these Olympics. The deficit to Australia didn’t last long, as Amanda Chidester plated two runs with a single in the bottom half of the inning for a 2-1 walk-off victory to move the U.S. to 4-0 in group play.

Extra-inning rules dictate an automatic runner on second, and Australia loaded the bases against Abbott, who allowed her sixth free pass of the game to put the U.S. in a 1-0 hole.

Leading off the bottom of the eighth, Haylie McCleney reached on an infield single, with auto runner Ally Carda remaining at second. Janie Reed moved both runners into scoring position with a sacrifice bunt before Chidester laced one up the middle to win it.

Abbott struck out 13 and delivered 126 pitches. She’d gone 15⅔ innings without allowing a run, with two saves in relief of Cat Osterman against Italy and Australia. Abbott led the way in a 1-0 victory over Canada on Thursday.

The U.S. will face rival Japan on Monday in the final game of the round-robin.

Murray said in a statement he suffered a quad strain and, on the advice of team doctors, has decided to focus on doubles with partner Joe Salisbury. The pairing won its first-round match on Saturday, upsetting the French team of Nicolas Mahut and Pierre-Hughes Herbert, which was seeded No. 2.

Golden swim for Kalisz

Iconic theme music is back on NBC

Pro hoops fans from the 1990s and early 2000s will feel a twinge of nostalgia during NBC's coverage of Olympic basketball in Tokyo. The "Roundball Rock" theme song the network used for the NBA on NBC from 1990-2002 will be featured on its men's and women's basketball telecasts.

Composed by John Tesh, "Roundball Rock" became synonymous with the Michael Jordan-era Chicago Bulls teams and its frequent national exposure extended into the Los Angeles Lakers' run of championships with Shaquille O'Neal and Kobe Bryant.

(The theme even spawned a 2013 Saturday Night Live skit featuring Jason Sudeikis as Tesh.)

The first (re)appearance of the Olympics will come when Team USA meets France in its Olympic opener on Sunday (8 a.m. ET).
