What the Winter Plan does with Gonzalez: its decisions feed, the dated moves and the briefs

The plan trades him to Houston for Isaac Paredes: valued at $3.0M of a $16.4M package (the price Keystone expects Houston to ask: $16.0M).

  • ≈ Nov 1–Dec 1 Acquire Isaac Paredes (HOU) for Jacob Gonzalez (FV 35+) + Jhostynxon Garcia (FV 45)After HOU's option call (≈ Nov 1–5), before the CBA expires. HOU holds a $13.35M club option on him for 2027.
  • Fix third basedue Dec 1 · medium confidence

    Acquire Isaac Paredes (HOU) for Jacob Gonzalez and Jhostynxon Garcia once Houston exercises his $13.35M option (≈ Nov 1–5), and close before Dec 1: +2.6 wins, taking the plan to 81.7 (80% range 70–94) and 44% playoff odds, for $12.6M of 2027 payroll and $16.4M of prospect value. His value is the bat; his glove rates below Jared Triolo's. On price alone the trade is short of the market price of a win (0.90 wins per $10M against 1.11); the case is that nothing else gets its wins: the next option without a draft-pick cost adds 1.0 fewer. He is under control only through 2027: third base reopens for 2028.

Weakest middle-in (−2.7), but only 1.2 standard errors from average on 34 pitches: no in-zone spot to attack yet.

A spot is called only when it is farther from average than the best or worst of nine average cells gets 95% of the time (set from the league’s own pitches: about 3 standard errors above, 2 below).

* Estimated: RosterResource has no contract row for him, so control through 2032 estimated from his MLB debut (2026-05-31): six years of service at the earliest; he isn’t in the contract data, and time in the minors would add seasons; pre-arbitration years at the minimum, arbitration years from Keystone’s arbitration model.
