BOSTON — When he takes the mound for the first time at Fenway Park on Wednesday for his major league debut, Red Sox rookie Brayan Bello will have the advice of one of the best to ever pitch there on his mind.

Pedro Martinez was one of Bello’s idols from growing up in Samana in the Dominican Republic to working in the Red Sox baseball academy in that country. The Boston Hall of Famer told Bello when he reached the big leagues, not to overthink it.

“He just told me it’s the same baseball I’ve been playing from High A to Double-A to Triple-A to the big leagues. Don’t change anything,” Bello said through a translator Tuesday. “It’s the same distance from the mound to home plate, same batter, same baseball. Don’t change anything.”

He hasn’t spoken to Martinez yet since getting the news.

“I haven’t talked to him last night or today, but I know I’m going to talk to him pretty soon,” he said.

Bello entered the year as the Red Sox No. 4 overall and top pitching prospect. His speedy rise through the minor has increased anticipation for his debut. Before being summoned to Boston, Bello was a combined 10-4 with a 2.33 ERA and 114 strikeouts in 85 innings in Portland and Worcester.

He said he felt ready.

“I’ve been working really hard every step of the way. Double-A, Triple-A, I feel ready right now to go out there and perform,” he said. “I don’t get too nervous, but I’m really happy to be able to make my MLB debut here at Fenway. I’ve been working really hard for this moment to be here. I’m excited. I’m just ready to go. … I just hope I have a good debut, a good outing and everything goes well.”

He won’t be activated until Wednesday but was getting the lay of the land Tuesday as he prepared to watch the game from the dugout.

“I’ll just watch the game from here and watch the hitters and how the pitchers are working the batters and try to translate that for tomorrow,” he said.

Alex Cora has been keeping track from afar. He watched Bello run hills and work out during the offseason on Instagram. The manager heard the glowing reports about his performances, his attitude and approach from both Double and Triple-A.

“This kid, he wants it. He wants it bad,” Cora said.

While Martinez’s advice was not to let the moment get too big, Cora wanted him to make sure he enjoyed it.

“We get excited about the players, especially in the region. Let’s chill tomorrow and let him enjoy it,” Cora said. “Whatever happens, happens. This kid is going to be an important part of this organization for a long, long time. But tomorrow is about going out and being a big leaguer.

“If being a big leaguer is going five with no runs, so be it. If it’s three and he gives up seven, be it too. It’s like I told Kutter (Crawford) last year and Winck (Josh Winckowski) early on, you work so hard to get here. You play here one day and you’re a big leaguer,” he added. “Let’s enjoy and see where it takes. Tomorrow is going to be a great day, not only for him but for the whole organization, player development and everyone who has been involved with this from the Dominican although the way to tomorrow.”
