On Monday, Oct. 5, the Arizona Diamondbacks revealed that right-handed pitcher David Hagaman is their 2026 Minor League Pitcher of the Year.

Hagaman, 23, was the No. 133 overall draft pick back in 2024.

After working his way up to A+ ball in 2025, the New Jersey native pitched at both A+ and Double-A this season.

In total, he threw 35.1 innings at Double-A Amarillo, but ended the year with a stellar 2.87 ERA in a grand total of 106.2 innings pitched.

Hagaman now has a career 8-7 record, and it should come as no surprise that he picked up seven of those wins this season.

The West Virginia graduate started 22 games this season and is up to 35 career starts in his young career.

Pitching has been a major focal point with the Diamondbacks. Their big-league rotation could use some work, to say the least, so it's great to know they have a player like Hagaman who's been getting a ton of praise after a strong 2026 season.

Currently, he's the team's No. 4 prospect and has a 2027 ETA.

It doesn't matter what level someone is pitching at to qualify for the organization's pitcher of the year award; it just boils down to how many innings they threw and how good their stuff truly is.

With Hagaman, he struck out 86 batters and walked 33 at A+ this season. In those 15 starts, opponents hit just .221 against him, and that's a number that barely rose when he made the jump to AA.

Hagaman was able to get four batters to ground into double plays at A+, and he averaged just over 16 pitches per inning, a number that would actually go down at Double-A.

His 1.30 WHIP at the A+ level was great to see for someone his age who only made five starts there the year prior. 

The biggest thing to note when looking at Hagaman's Double-A numbers is the sample size. Obviously, some of these numbers are going to be a bit skewed, knowing he only threw 35.1 innings in seven starts compared to his 71.1 innings in 15 starts.

Making the jump to Double-A as a relative newcomer is never easy, but Hagaman passed the test with flying colors.

His pitches per inning average fell by nearly a pitch and a half, and his WHIP dropped to a staggering 1.16.

Hagaman's 2.25 ERA at Double-A clearly gives the organization a lot to look forward to with his development, and there's a strong chance he could appear at Triple-A during the 2027 season.
