Let the record show that the Red Sox posted a 7-3 record during their longest homestand of the season, which concluded yesterday with another no-sweat-required victory, 6-1 over the meek Houston Astros.

But the enduring image may have come in the fifth inning.

After banging an RBI double off The Wall, Mike Carp stood on second base, turned to face the dugout and flexed both biceps — a nod to outfielder Jonny Gomes, who struck the pose after his eighth-inning double April 20 in the first game played at Fenway Park following the Marathon bombings and the Watertown manhunt.

Gomes may have been first to invoke “The Flex,” symbolic of the “Boston Strong” rallying cry and captured on the cover of Sports Illustrated last week, but it has been copied by others. First baseman Mike Napoli was spotted doing it after hitting a double Friday night, and Carp took his turn yesterday.

“If it makes the cover of SI, I’m sure it’s going to friggin’ stick,” Gomes said after the Red Sox won their fifth consecutive game and tied a franchise record with 18 April victories. “It’s kind of international, Boston as a whole. Granted, she’s still just a flex, but I think it plays pretty heavy in this area.”

And as the wins pile up and the chemistry grows, the best-in-the-majors Red Sox suddenly have their answer — albeit one born out of an unspeakable tragedy — to the Texas Rangers’ claw-and-antlers ritual after every big hit en route to winning back-to-back AL pennants in 2010-11.
