Alfonsin Rosario is wasting no time trying to put a rough finish behind him.
The Cleveland Guardians outfield prospect is spending the winter in Venezuela with Bravos de Margarita, and the early returns have been loud. Rosario, 22, is one of the youngest players in the league by a wide margin - more than six years younger than the average player - and he’s already flashing the kind of pop that has made him one of the more interesting bats in the system.
In his latest game, Rosario went 2-4 with two runs scored, two RBIs and a stolen base. One of those hits was his first home run in the Venezuelan Winter League, a blast that drew attention from Guardians Prospective, which wrote:
“Cleveland #Guardians 22yr old OF prospect Alfonsin Rosario collected a pair of hits today (2-4 2R HR 2RBI SB) driving in two runs including an absolute rocket for his 1st HR in the Venezuelan Winter League for his club Bravos de Magarita! First 4 games of LVBP: 4-15 3R 1HR 3RBI 3BB 3SO 1SB AVG .267 OBP .389 OPS .856,” Guardians Prospective wrote.
Over his first four games with Margarita, Rosario is 4-15 with three runs, one homer, three RBIs, three walks, three strikeouts and one stolen base. That line leaves him at a .267 batting average, a .389 on-base percentage and an .856 OPS.
None of that is especially surprising when you look at the profile. Rosario is a 6-foot, 222-pound right-handed hitter with real strength, and he showed it in a big way at Double-A Akron earlier this year.
In 66 games with the RubberDucks, he hit .270 with a .350 on-base percentage, a .569 slugging percentage, 16 home runs, 52 RBIs and 12 stolen bases. That production pushed his OPS to .918 and earned him a promotion to Triple-A Columbus on July 13.
Triple-A was a different story. Rosario struggled in his first run there, batting .163 with two home runs and 65 strikeouts in 164 plate appearances across 42 games.
He was more than four years younger than the average International League player, and the step up clearly exposed the swing-and-miss in his game. He finished 2026 with 18 home runs, 62 RBIs, 17 stolen bases and a .774 OPS across both levels, but the strikeout total climbed to 155.
That has been the recurring issue. Rosario struck out 147 times in 2024 and 137 times in 2025, even while continuing to bring power and speed to the table. He has now topped 15 home runs in each of the last three seasons, and in 2025 he hit 21 homers with an .806 OPS.
His route to the Guardians wasn’t a straight line, either. The Chicago Cubs drafted Rosario in the sixth round in 2023 out of P27 Academy in Lexington, South Carolina, and he reached Cleveland’s organization before the 2025 season. The Guardians liked enough of what they saw to invite him to big league camp this past spring.
For Rosario, this winter is a chance to reset and sharpen his approach against quality pitching. If he can trim the strikeouts without losing the power and speed that make him dangerous, he could be in line for another shot at Triple-A next spring. And for a Guardians organization that could use more right-handed pop in the outfield, a strong winter from Rosario would count as a welcome development.

Guardians Face A Tough Call On A Top Prospect Soon
Jaison Chourio has climbed steadily through the Guardians minor league system and is now at Triple-A, putting him on the doorstep of a decision Cleveland has been preparing for. The organization is expected to add him to the 40-man roster soon, a move aimed at keeping him out of the Rule 5 Draft and preserving one of the more intriguing young players in the system.
For the Guardians, it is the kind of roster call that comes with both urgency and patience. Chourio is viewed as a top prospect, but he still appears to be about a year away from making a regular impact in the majors, which means Cleveland has to balance protecting his future with the realities of a crowded roster right now.

Former Guardians Prospect Gets Another Shot With A Contender
Christian Cairo is getting another fresh start, this time with a contender that has a long track record of turning depth pieces into useful big league options. The former Guardians prospect was claimed off waivers by the Dodgers from the Mets, adding another stop to a pro career that has already taken him through four organizations over seven seasons without a major league appearance.
For Cleveland fans, Cairo remains one of those familiar names who never quite got the call despite sticking around the game and keeping himself in the mix. The Dodgers made a second roster move the same day by re-signing infielder Tyler Fitzgerald to a minor league deal, a reminder of how quickly the margins can shift for players trying to stay positioned for a breakthrough.

Guardians May Have Another Future Core Infielder On The Rise
Welbyn Franciscas rapid climb has given the Guardians another name to watch in the middle infield pipeline. The 20-year-old switch-hitting infielder from the Dominican Republic signed with Cleveland in 2023 and reached Double-A Akron this season, then backed up that progress with a strong showing in the Arizona Fall League. That combination was enough to land him at No. 98 on Bleacher Reports Top 100 prospect list, a notable step for a player still early in his professional career.
For a Cleveland system that has long valued homegrown infield talent, Franciscas rise adds to the sense that the organization may have another future core piece developing in plain sight. He is one of four Guardians prospects included on the list, which weighs both current ability and long-term upside, and his placement suggests evaluators are taking notice of how quickly his tools are translating. The next test will be whether he can keep that momentum going as he moves closer to the upper levels. [Read more 🡒]
