Manager Alex Cora said Saturday that Bello (shoulder) is still behind schedule but is progressing well, Rob Bradford of WEEI.com reports.

EDGE Analysis

Bello began experiencing shoulder soreness early on in camp, and with just over two weeks left in spring training, it's becoming increasingly likely that he'll require a stint on the injured list to open the season. Should that be the case, Quinn Priester and Richard Fitts would be the leading candidates to fill the open spot in Boston's rotation.

Bello (shoulder) will throw another bullpen session Monday, and manager Alex Cora said the organization is "still shooting for him to be on the Opening Day roster, but obviously it's March 2 now," Ian Browne of MLB.com reports.

EDGE Analysis

The right-hander was briefly shut down at the start of camp due to shoulder soreness, so he's a bit behind in his preparations for the start of the regular season. Bello still has more than four weeks to ramp up ahead of Opening Day and has a realistic chance to be available -- especially since he probably wouldn't be pitching in the first couple games of the season anyway -- but he may need a clean buildup the rest of the way to avoid an IL stint to begin the campaign.

Bello (shoulder) threw a bullpen session Friday, Ian Browne of MLB.com reports.

EDGE Analysis

Bello threw approximately 30 pitches at about 70-to-75 percent intensity. The 25-year-old right-hander has been slowed by shoulder inflammation and is at the edge of having enough time to be ready for start of the regular season, May 27 in Texas. Unlike 2024, when Bello was given the Opening Day start, that honor is expected to go to Garrett Crochet this season. As such, Bello could still be available at the back end of the rotation for the first week.

Bello (shoulder) will throw a bullpen session Friday, Christopher Smith of MassLive.com reports.

EDGE Analysis

Bello has been slowed in camp by right shoulder soreness but has been throwing on flat ground without issue and will take the next step in his throwing progression Friday. The Red Sox remain optimistic that the right-hander has enough time to be ready for Opening Day, but Bello will have to continue showing progress without having any setbacks.

Bello (shoulder) is expected to be ready for the start of the season, Peter Abraham of the Boston Globe reports.

EDGE Analysis

This is a fluid situation, as Bello has been throwing from 90 feet and will need to avoid any setbacks, but he's at least more likely to be ready than teammate Kutter Crawford (knee), per Abraham's report. Lucas Giolito (elbow) is also expected to be ready for the start of the season.

Bello (shoulder) has extended his throwing program to 90 feet and will undergo a strength test Sunday, Christopher Smith of MassLive.com reports.

EDGE Analysis

The right-hander was shut down briefly at the start of camp due to shoulder soreness, and he's still building up his arm strength before progressing to bullpen sessions. Bello's availability for the beginning of the regular season remains up in the air, and he may need to return to mound work soon to avoid a delayed start to the campaign.

Bello (shoulder) isn't yet throwing bullpens and isn't likely to be ready to pitch in games for at least a week, Chris Cotillo of MassLive.com reports.

EDGE Analysis

Bello was recently shut down due to shoulder soreness, and though he's since been able to resume throwing, he hasn't yet tossed a bullpen session. Manager Alex Cora hasn't ruled Bello out from being ready for Opening Day, instead saying, "We'll see how it goes next week" in reference to the hurler's outlook moving forward. The Red Sox are already experiencing rotation issues, as Kutter Crawford's Opening Day status is in doubt due to a knee injury and Lucas Giolito began camp a few days behind other pitchers as he builds up following the internal brace procedure he underwent last March.

Manager Alex Cora said Friday that Bello was shut down for a few days due to shoulder soreness but has resumed throwing, Christopher Smith of MassLive.com reports.

EDGE Analysis

It's encouraging that the right-hander is already back to throwing, but any arm issues early in camp are a concerning development. There's no indication that Bello's availability for the start of the regular season has been affected, but it's worth keeping an eye on his progress as spring games get underway.

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.

EDGE 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, a 1.36 WHIP and a 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.

Bello (14-8) took the loss against Tampa Bay on Thursday, allowing one run on five hits and two walks while striking out seven batters over 5.2 innings.

EDGE Analysis

Bello didn't allow any extra-base hits, and the only run he allowed came on a pair of singles and a sacrifice fly in the third inning. However, Boston's offense managed just one hit and zero runs, pinning the right-hander with a hard-luck loss. Bello nonetheless continued a strong stretch during which he's allowed a modest four runs over his past 16.1 frames across three starts.
