About Cleveland Guardians Franco Aleman:

Aleman was the third pitcher Cleveland chose in the 2021 draft. They also selected right- handers Tommy Mace, and Jack Leftwich. Aleman is the first of the group to reach the parent Guardians.

Aleman has spent parts of six seasons in his minor league development.

Much of his time was interrupted by injuries. Aleman missed nearly three months during 2024 because of an oblique strain suffered in May.

He needed left hip hernia surgery during spring training in 2025, and did not join Columbus until May 6.

Scouting Cleveland Guardians Franco Aleman:

Aleman was promoted to Cleveland from Triple-A Columbus, where he went 1-1, with a 0.00 ERA, and 0.58 WHIP in 13 games, covering 12 innings.

His fastball/slider combination was electric, and he earned his way to the parent Guardians by dispatching hitters with relative ease.

Aleman made his major league debut for the Guardians on May 10, 2026, when he pitched two innings against the Minnesota Twins. He yielded no runs, two hits, walked none, and struck out one.

In his relief role, Aleman relies on that combination of a four-seam fastball, and a wicked slider in his two-pitch mix.

brooksbaseball.net tracked his May 10 outing with a 96.97 miles per hour fastball, and 85.69 miles per hour slider.

Aleman used his fastball 78.33% of the time, with the remainder of the pitches being the slider.

For this old scout, Aleman’s fastball is a Grade 60, which equates to an All Star quality pitch.

His slider is a tick below in quality, but still, it is an above average pitch.

msn.com says, “For the last three seasons, 2024-2026, Aleman has been working on his command and control, all while perfecting his pitching arsenal.”

Aleman has long limbs, making keeping command and control in check a priority. If he alters his delivery in any way, he can elevate his pitches, or lose command of the strike zone.

But his size should be an asset as he moves forward.

Aleman projects to be a late-inning set-up reliever, which is a role Cleveland can certainly use.

The Cleveland Guardians have strengthened their bullpen with Aleman. However, they still face issues with starting pitching depth.

nextyearincleveland.substack.com states: “At his best, Aleman’s long limbs and big arm swing combined with his low release and big velocity, can get on top of hitters with a vicious sinker in the upper 90’s.”

So far, he hasn’t thrown that sinker in Cleveland. But it could be as solid a pitch s described above.
