As MLB free agency reshapes rotations and lineups, expect low-cost starters like Lucas Giolito or Zac Gallen to attract interest — bettors could target shortened odds on teams signing them and back Baltimore to improve its rotation after adding Pete Alonso. Short-term power signings such as Marcell Ozuna may offer value in HR/RBI prop markets, while Tatsuya Imai’s 2026 arrival shifts long-term run-line expectations.
MLB Offseason Movers: Rotation Targets, Power Additions and Betting Angles
After notable MLB offseason signings, teams continue hunting complementary pieces. These aren’t always marquee stars, but players with clubhouse value and specific skill sets can tilt playoff odds and betting lines.
Framber Valdez: Experience and Recent Friction
Framber Valdez remains a two-time All-Star whose late-season communication issues with his catcher raised questions about his fit after missing the playoffs. Teams weighing rotation stability will consider both his pedigree and recent red flags when setting odds and assessing value on season-long markets.
Tatsuya Imai: High upside, long-term arrival
Houston has reportedly signed Japanese standout Tatsuya Imai, who is expected to arrive in MLB in 2026. Imai is a future-facing pickup that won’t affect immediate odds for 2025 but will influence longer-term futures and prospect-based markets once his debut nears.
Teams Targeting Rotation Upgrades
Baltimore, having prioritized a major bat by signing Pete Alonso, is now focused on landing an innings-eating starter to anchor its rotation. Clubs that already added offense are pushing payroll toward pitching upgrades, which should shorten odds for teams linked to reliable starters.
Lucas Giolito: Bounce-back candidate for low-pay suitors
Lucas Giolito has been labeled “unlucky” recently, with injuries and inconsistent free-agent stretches. His profile appeals to low-payroll franchises seeking upside — a market where bettors might find value on signing props or speculative futures if teams view him as a Cease replacement.
Zac Gallen: Turning a down year into opportunity
Zac Gallen declined a qualifying offer and posted a 4.83 ERA in 2025, diminishing his free-agent ranking. Still, teams like San Diego are considering him as a rotation option. Bettors should watch Gallen’s landing spot: moving to a pitcher-friendly park or a strong defensive club could materially improve his projections and betting lines.
Power Options and Short-Term Contracts
Marcell Ozuna remains a proven run producer after six seasons with Atlanta. His recent stretch (since 2023: 100 HR, 272 RBI, .867 OPS) makes him an attractive short-term target for teams wanting instant offense without a long-term commitment.
Eugenio Suárez: Impact bat with defensive questions
Eugenio Suárez delivered a playoff-clinching grand slam that pushed his team to a 3–2 lead before they faltered in Toronto. His bat remains valuable, particularly in lineups seeking power, though defensive limitations at third base temper his overall valuation.
Betting Implications and Market Moves
Expect movement in several betting markets:
- Team futures: Baltimore’s rotation search could shorten their odds if they land a frontline starter; bettors may act early on rotation-driven price shifts.
- Player props: Short-term signings like Ozuna present clear HR/RBI prop opportunities, especially in partial-season or late-season markets.
- Speculative value: Giolito and Gallen offer upside in under-the-radar signings; back them in low-cost futures or signing props if landing spots improve their park or defensive support.
- Long-term futures: Imai’s arrival affects multi-year outlooks and prospect-based markets once his MLB date approaches.
What bettors should monitor
Landing spots and park factors. Contract length and role (rotation vs. swing starter). Recent health history and catcher/rotation chemistry. Any trade or signing that pairs a pitcher with a strong defense can materially alter expected ERA and strikeout prop lines.
Bottom line
This offseason is shaping around targeted additions rather than blockbuster splashes. Rotational adjustments and short-term power signings will drive betting value in team futures, player props, and signing markets.
Monitor destinations closely — a single signing can flip both on-field expectations and odds for bettors.
