The Celtics lost to the Heat 103-84 in Game 7 of the Eastern Conference Finals on Sunday, falling short of the 3-0 series comeback at the final hurdle.

The Heat now move on to face the Nuggets in the NBA Finals.

The Red Sox also lost on Sunday, dropping the finale of a three-game series against the Diamondbacks, 4-2. Boston begins a new three-game set against the Reds at Fenway Park tonight at 7:10 p.m.

Marcelo Mayer’s promotion: In 2021, the Red Sox held the No. 4 overall selection in the MLB draft, the team’s highest pick since 1967.

Boston used it to draft shortstop Marcelo Mayer, an 18-year-old with immense potential.

Since being picked, Mayer has spent time in the lower part of the Red Sox minor league system as he acclimates to the rigors of the professional game.

In 2023, he hit .290 with an .890 OPS (and seven home runs) in High-A minor league baseball with Boston’s Greenville affiliate. This includes a recent stretch in which Mayer has been particularly prolific, batting .321 in May with six home runs and a .998 OPS.

The result is that the Red Sox are promoting Mayer to Double-A Portland on Tuesday, as first reported by Alex Speier of The Boston Globe.

At just 20, Mayer is the youngest Red Sox draftee to reach Double-A since Anthony Rizzo and Casey Kelly in 2009.

His coaches and Red Sox executives have had nothing but praise for the emerging prospect.

“The ceiling is high and his ability to make adjustments, his ability to learn, and to improve — he’s not slowing down,” Red Sox director of hitting development Jason Ochart said of Mayer, per Speier. “He’s already got above big-league average bat speed and he still has room to develop physically. He’s going to keep learning his approach and learning how to be a hitter. He’s really, really special.”

Standing at 6-foot-2-inches and capable of making plays both at the plate and in the field, the current No. 1 Red Sox prospect — who had not been projected to move to Double-A so quickly — seems to be progressing ahead of schedule.
