BOSTON — The ALS Ice Bucket Challenge is back in full swing.

The Red Sox joined Pete Frates and Pat Quinn, co-founders of the challenge, in relaunching the successful fundraising campaign Friday at Fenway Park. The entire team, including nine-time All-Star David Ortiz and manager John Farrell, participated in the relaunch, during which players yelled and laughed as they dumped buckets of ice water on each other.

The Ice Bucket Challenge, which aims to raise awareness about amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s Disease, became incredibly popular last year. The campaign went viral on social media and was so successful that Frates, Quinn, the Red Sox and others are doing it again this summer.

“To be associated with the Frates family, to help bring attention to a devastating disease, we’re honored and proud to be part of that,” Farrell said Friday. “And yet at the same time, we’ve been able to see firsthand the effects of (ALS), and it’s devastating.

“Pete has been incredibly brave and forthright in his involvement to bring attention to it. And to see how far that awareness has gone globally — because when we kicked it off, I think there were five other countries who were kicking theirs off at the same time around the globe — it’s pretty amazing what his initiative has done worldwide.”

Frates, a Massachusetts native and former captain of the Boston College baseball team, was diagnosed with ALS in 2012. He’s long been connected to the Red Sox, as each are striving to strike out ALS.

The Red Sox challenged the Los Angeles Dodgers, musician Zac Brown and all of Red Sox Nation to participate in the Ice Bucket Challenge.
