Diamonds legend Osco “Osco” Adelsteins passing was announced Tuesday on the Diamonds website.

A day earlier, Adelstins wife, Jennifer Adelston, posted on her Facebook page that she was “saddened” to hear of his passing.

The Diamonds released a statement on the news.

“Osso’s passing is a huge loss to the Diamond family.

He was a tremendous athlete, a beloved husband and father of two children and a devoted friend to all,” the statement read.

“We will miss him dearly.

Please keep him in your prayers.”

Adelstein played six seasons with the Diamondbacks from 1971 to 1978, winning three Gold Gloves, one Silver and one Bronze.

He also played in the majors with the Chicago Cubs, Philadelphia Phillies and Baltimore Orioles.

He was a teammate of Diamonds pitcher Curt Schilling, who was a former teammate of Adelsten’s in Chicago.

Adelselsteins final start for the Cubs was on Sept. 22, 1977, in the NL Division Series against the St. Louis Cardinals.

He had six career postseason hits.
