May 10, 2025 5:31 PM : Martinez (shoulder) will throw a bullpen session Sunday, Nick Piecoro of The Arizona Republic reports.
Analysis: Manager Torey Lovullo said Saturday that the ball has been "sizzling" out of Martinez's hand during his throwing program, which is a sign that the 23-year-old is feeling good after landing on the injured list May 1 with shoulder inflammation. Assuming all goes well during his bullpen session, Martinez may still be on pace to return when eligible next Friday.
