Chris Ruffolo highlighted the Oakland Athletics as a team to watch for future betting opportunities due to key offseason improvements and roster developments. He specifically mentioned the acquisitions of veterans Luis Severino (signed on a two-year deal), left-handed pitcher Jeffrey Springs from Tampa Bay Rays, and reliever Jose Leclerc as promising signings to bolster the pitching staff and bullpen depth. Additionally, Ruffolo praised Oakland's young core, including catcher Shea Langeliers, prospect Zack Gelof, infielder Tyler Soderstrom, and several solid outfield talents like JJ Bleday, Seth Brown, Lawrence Butler, and Esteury Ruiz — particularly noting Ruiz's base-stealing ability and Brent Rooker's power upside. Ruffolo advises bettors to identify situations this season when the young Athletics roster could offer substantial betting value despite generally low expectations.
