Boston right-hander Brayan Bello has been shut down until Monday due to right forearm soreness.

“After his last bullpen, he felt soreness,” Manager Alex Cora said. “He’s so important to the organization and what we’re trying to accomplish. He’ll be back on his throwing program Monday.”

The 23-year-old Bello is a candidate to make the club’s starting rotation this spring.

“It was last week, I was throwing. I didn’t feel any pain. I felt tight and I didn’t want to force it,” he said through a translator Saturday morning. “I feel much better right now. I’ve been working really hard to get ready.”

Last year, he was promoted from Triple-A and pitched in 13 games, making 11 starts and going 2-8 with a 4.71 ERA.

“I feel very anxious. I want Monday to come,” Bello said. “It’s the first time I’ve experienced something like this.”

In December, Bello worked out at the home of Hall of Famer Pedro Martinez in the Dominican Republic.

ARBITRATION: Seattle outfielder Teoscar Hernández was among five players who lost their salary arbitration cases and Los Angeles Angels outfielder Hunter Renfroe won as teams finished with a 13-6 advantage in decisions.

Angels infielder Gio Urshela, Tampa Bay pitchers Colin Poche and Ryan Thompson and St. Louis reliever Génesis Cabrera also lost their cases.

Hernández will receive $14 million instead of his request for $16 million, still the highest salary for a player in a case that went to a decision. It topped the $13.5 million for both Gerrit Cole and Max Fried.

Renfroe will get $11.9 million instead of the team’s offer of $11.25 million.

The 19 hearings this year were up from 13 last year and the most since 22 in 2018.

Among the 33 players who exchanged proposed salaries with their teams on Jan. 13, 14 reached agreements without hearings.

BREWERS: Milwaukee signed left-handed pitcher Justin Wilson to a $1 million, one-year contract and placed right-hander Jason Alexander on the 60-day injured list.

Wilson gets an $850,000 salary this season and the Brewers have a $2.5 million option for 2024 with a $150,000 buyout. He can earn additional performance bonuses.

Wilson, 35, went 0-1 with a 2.45 ERA in 3 2/3 innings over five April relief appearances for the Cincinnati Reds last season. He had Tommy John surgery last June 3.

BRAVES: Bad news for the rest of the National League: The reigning Rookie of the Year doesn’t sound all that satisfied with his debut season.

Atlanta’s Michael Harris II – whose callup last year propelled the Braves to 101 wins and a division title – said Saturday he “had an all right season, I guess,” and then responded with more modesty when asked if that’s really how he feels about 2022.

“Some things I had to work on, but it was decent. I’ll try to do better,” Harris said. “Kind of like to hold myself to a higher standard.”

There’s no telling how good the 21-year-old center fielder can become. Harris hit .297 with 19 home runs, 64 RBI and 20 stolen bases after jumping from Double-A to the majors. Atlanta was below .500 when Harris made his debut May 28. Shortly thereafter, the Braves went on a 14-game winning streak.

Harris and Atlanta teammate Spencer Strider finished 1-2 in the Rookie of the Year vote.

“It means a lot. I know you can only win it once,” Harris said. “I guess that made it mean so much more.”

Harris starts a $72 million, eight-year deal in 2023 that could be worth $102 million over 10 seasons. So the DeKalb, Georgia, native could be playing in Atlanta for a while.

WHITE SOX: When Michael Kopech started throwing again after right knee surgery, he felt a sense of relief.

It was a real issue that prevented him from being himself for much of last season with the Chicago White Sox.

“Absolutely. There’s a little bit of relief knowing that I wasn’t just trying hard and it not coming out last year,” Kopech said. “There was something that I had to fight through, which take it with a grain of salt. I’m going to battle through everything that I have to battle though. But ultimately, I want to be as healthy as I can and I’m on track to do that now.”

The 26-year-old Kopech went 5-9 with a 3.54 ERA in a career-high 25 starts in 2022. But he left a June 12 game against Texas with right knee discomfort, and it became a lingering issue for the rest of the year.

The right knee trouble quite possibly played a role in Kopech going on the 15-day injured list in August with left knee discomfort. He went back on the IL on Sept. 17 with right shoulder inflammation, ending his season.
