The Red Sox and Brayan Bello are in agreement on a contract extension that will keep the homegrown starting pitcher in Boston for the remainder of his club control as well as his first two years of free agency.

A source confirms that Bello’s deal is for six years and $55 million with a $21 million club option for the 2030 season. As the Herald previously reported, the right-hander will receive a signing bonus ($1 million) and the contract includes escalators.

While the average annual value (AAV) of Bello’s contract adds $9.16 million to Boston’s luxury tax payroll for each of the next six seasons, a source tells the Herald that the bulk of the total salary will be paid out in the latter half of the decade.

Bello, who will celebrate his 25th birthday in May, is entering his second full season in the Majors. He was dominant for most of ’23; after a rough season debut, he posted a 2.56 ERA and held opposing batters to a .223 average and .635 OPS over his remaining 13 starts before the All-Star break. As was the case with most of the Sox, the righty struggled down the stretch, particularly in September, when 22 earned runs over his remaining five starts (26 innings) brought his season totals to a 4.24 ERA over 28 starts.
