Jayson Tatum’s season debut proved coexistence won’t be an issue for the Celtics Jayson Tatum’s debut was an encouraging step forward on Friday night.

Jayson Tatum made his Celtics season debut against the Mavericks, playing 27 minutes. In that time, he made an impact that immediately debunked any doubt about his ability to gel with Boston's offense.

Jayson Tatum: “It was a surreal feeling, but then it felt normal. So that was really promising for me, not even when the game started. Just driving to the game, starting my routine, doing my pregame shooting. I knew it was a big moment, but everything just started to feel really normal again.”

Seth Lugo set the tone for Team Puerto Rico, delivering four scoreless innings, allowing just three hits against Team Colombia. Lugo most notably escaped a second-inning jam with runners on 2nd and 3rd before PR got on the board.

Strong way to open up the WBC for Team Rubio.

Why the debate over Jayson Tatum’s role is meaningless This topic is getting old — really old.

It’s been over nine months since Jayson Tatum last played for the Celtics. Friday night against the Mavericks could finally be the moment Boston has been eagerly waiting for all season.

Before that moment arrives, let’s put one debate to rest. www.celticsblog.com/boston-celti...

Baseball Bluesky will (I hope) be busy, but I would like specifically to plug @giojrivera.bsky.social's coverage. Not only does he know his stuff, he's paying particular attention to the team starting with a strike against it that somehow fits the moment in all the depressing ways we grow used to.

Yes, Puerto Rico has a legit gripe with MLB before the 2026 World Baseball Classic Major League Baseball has applied uneven standards to Latin American teams in this year’s World Baseball Classic. Why?

I’ll be covering the 2026 World Baseball Classic independently on my Substack, focusing on Team Puerto Rico.

Jaylen Brown shoulders the blame after ‘uncharacteristic’ Celtics loss to Hornets “Being the leader, I take accountability.”

Jaylen Brown pointed the finger at himself after the Celtics suffered a brutal, lopsided loss to the Hornets on Wednesday night. Reflecting on Boston’s 89-point outing on 38 percent shooting, Brown admitted the obvious:

“That wasn’t Celtics basketball.”

Why Hugo González was unfazed guarding Giannis Antetokounmpo — even with the Celtics shorthanded “We got our standard, and we just want to maintain it.”

Hugo González went from playing 13 minutes to making his third NBA start against the Bucks the next night. He rewarded the Celtics with a career-best performance and even embraced the challenge of guarding Giannis Antetokounmpo.

‘It’s formulated’: Jaylen Brown on Celtics identity Boston improved to 40-20 with Sunday night’s DNA-defining victory over Philadelphia.

Boston may have missed the 40-before-20 benchmark, but Sunday night’s win over the Sixers (their 40th) showed just how far the inexperienced, underdog, Jayson Tatum-less Celtics have come.

“Everybody did their part.”
