25-Year-Old PitcherSP
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
RANKS
From Preseason
$Signed a six-year, $55 million contract extension with the Red Sox in March of 2024. Contract includes $21 million team option for 2030.
Inefficient in no-decision
PBoston Red Sox
September 25, 2024
Bello came away with a no-decision in Tuesday's 6-5 extra-inning win over the Blue Jays, giving up two runs on two hits and two walks over four innings. He struck out four.
ANALYSIS
While the right-hander didn't pitch poorly, Bello needed 75 pitches (42 strikes) to record his 12 outs, putting extra pressure on the Boston bullpen in a contest that eventually went to 10 innings. Bello wraps up his campaign with a career-high 14 wins, a 4.49 ERA, 1.36 WHIP and 153:64 K:BB through a career-high 162.1 innings, and the 25-year-old figures to be a key part of the team's 2025 rotation plans.

RotoWire Roundtable: 2025 Fantasy Baseball Top-300 Rankings
30 days ago
Shohei Ohtani takes the top spot in the first edition of the 2025 RotoWire roundtable rankings, but his lead is a very slim one.
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.
