ATLANTA — The Diamondbacks reinstated left-handed reliever Andrew Saalfrank on Thursday, June 5, following a one-year suspension for betting on baseball.

Saalfrank was returned to the 40-man roster. He was reinstated from the ineligible list and optioned to the Arizona Complex League

To clear space, right-hander Scott McGough was designated for assignment.

A year ago, Saalfrank was suspended for bets he placed in 2021 and 2022, when he was a minor leaguer working his way back from Tommy John surgery.

Saalfrank placed a total of $445.87 worth of bets — 28 of them MLB-related, another a college baseball parlay — on games between September 9, 2021, and March 9, 2022. Major League Baseball said at the time of the suspension that Saalfrank did not play in any of the games in which he placed a bet, nor did he wager on games involving his team.

Saalfrank played a key role on the Diamondbacks in 2023, logging 10 1/3 innings of scoreless relief work down the stretch, then recording some key outs during the postseason.

He made only two appearances in the majors last season prior to his suspension, giving up four runs in one inning.
