Boston Red Sox
2025 Fantasy Outlook
Bello signed a six-year extension during spring training, picked up an Opening Day win and early on looked like a No. 1 starter. Then the walks started. He went from 76th percentile in BB% (6.7) in 2023 to 33rd (9.1) in 2024. The right-hander managed to win 14 games but needed good run support during the rough patches. Bello's 4.49 ERA was the worst among starters with at least that many wins. Walks don't always kill, but they hurt during the first half when he allowed 14 home runs over 89.2 innings (1.4 HR/9) and entered the break with a 5.32 ERA. The walks didn't stop in the second half, but Bello was able to prevent damage through better location which kept the ball in the park; he allowed just five homers in 72.2 innings (0.6 per nine) following the break. The pressure to lead the staff won't be on the 25-year-old in 2025, as Bello should slot behind Garrett Crochet and Tanner Houck -- and possibly Walker Buehler. Read Past Outlooks

Earns win in 2025 debut
PBoston Red Sox
April 22, 2025
Bello (1-0) collected the win against the Mariners on Tuesday. He allowed one run on four hits and three walks while striking out three over five innings.
ANALYSIS
Tuesday was Bello's first start of the season after missing most of the first month of the season with a shoulder strain. He gave up a solo homer to Jorge Polanco in the first inning, but Bello managed to get out of a bases-load jam in the same frame to limit the damage to one run. Bello appeared to be in jeopardy of being lifted in the fourth inning due to right calf cramps, but he managed to gut it out and was able to make it through five innings on 97 pitches (51 strikes). He generated just seven whiffs and eight first-pitch strikes, but it was an encouraging season debut for the 25-year-old after posting a 6.52 ERA during his rehab assignment. Bello is lined up to face the Guardians on the road this weekend.

Past Fantasy Outlooks
2024
2023
Bello exhibited some improvement in his first full season, but he still has work to do if he wants to be a front of the rotation starter. He improved his control, but it came at the expense of strikeouts. Bello has the raw stuff to be more dominant, but he's yet to establish a third pitch to complement his sinker and outstanding changeup. Not only was his swinging strike percentage below average, but his called strike percentage was well below average, resulting in one of the lowest CSW% among pitchers throwing at least 150 innings. Bello has the arsenal to improve both swinging and called strikes, he just needs to find the right sequencing. Bello should have a rotation spot locked up and won't have any innings restrictions. The cost to see if he can take the nest step shouldn't be prohibitive, but he's in the wrong division, with the wrong home park to use in a streaming capacity.
After dominating at Double-A Portland and Triple-A Worcester, Bello was promoted in early July and immediately inserted into the Red Sox rotation. The righty was overmatched and sent back to Triple-A in early August. Bello was recalled three weeks later and gathered much better results. He registered a 3.12 ERA down the stretch, albeit with an inflated 1.56 WHIP, stemming from a .336 BABIP over that 36.1 inning sample. Bello needs to work on his control, but he throws 97-mph and possesses a plus changeup. With some fine tuning and seasoning, Bello could be a rotation staple. It remains to be seen if Bello makes the necessary adjustments and breaks camp in Boston's rotation.

Latest Fantasy Rumors
Season turned around?
PBoston Red Sox
August 21, 2024
Bello has a 3.57 ERA, 1.24 WHIP and 38:15 K:BB in 40.1 innings across his past seven starts.
ANALYSIS
The right-hander had a 5.55 ERA and 1.47 WHIP at the end of June, but he's pitched better of late and has lowered those figures to 4.80 and 1.41, respectively. Bello hasn't lost a start since June 25, but walks and homers continue to be a concern, as he has a 3.3 BB/9 and seven homers allowed in those last seven outings.
