~20% CUP. ECD May-July. Eldridge is slashing .360/.492/.520 through 13 Triple-A games with 10 walks. Rafael Devers is blocking him at first base. The outfield path is narrow but open.
Eldridge is slashing .360/.492/.520 through 13 games at Triple-A Sacramento. He has drawn 10 walks against 19 strikeouts, posted five doubles, and hit his first home run of the season. The Giants rank last in baseball in home runs and second-to-last in runs scored. He is not on their roster.
The model assigns Eldridge a ~20% CUP for a 90-day MLB appearance. The gating factor is not performance. Rafael Devers is the Giants' first baseman on a long-term contract, and Casey Schmitt has played well at the position since an 0-for-9 opening series. The Giants have said they have no promotional timeline. President of Baseball Operations Buster Posey has cited Eldridge's limited professional at-bats and his own experience of being sent down after a September cup of coffee in 2010. The path exists through the outfield if San Francisco's corner production continues to crater, but Eldridge has played only a handful of outfield games professionally.
Eldridge was selected 16th overall by San Francisco in the 2023 MLB Draft out of James Madison High School in Vienna, Virginia. He is 21 years old, listed at 6-foot-7 and 251 pounds. He was considered the best two-way prospect in his draft class, committed to Alabama before going pro. He signed for a below-slot $4 million bonus, allowing the Giants to add other picks.
He hit 25 home runs across three minor league levels in 2025, reaching Triple-A Sacramento in June after beginning on the injured list with a wrist issue. Over 66 Triple-A games, he posted an .851 OPS. The Giants called him up on September 15, 2025, making him the third player in franchise history to debut with San Francisco before age 21, alongside Matt Cain and Madison Bumgarner. He went 3-for-28 in 10 big league appearances, then required surgery to remove a bone spur from his left wrist in October.
He began 2026 healthy and optioned to Triple-A. His early numbers are better than his debut suggest he is. The wrist issue from September is gone.
Devers signed with San Francisco before 2026 and is batting poorly through the first month of the season. He is not losing his job. He is being paid to play first base. Eldridge's long-term home is either at first or DH, and both slots are occupied by players under contract.
The outfield path is the only realistic 2026 route. The Giants' corner outfield combination of Heliot Ramos, Harrison Bader, and Jung Hoo Lee has slashed a combined .159/.204/.241 through the team's first 15 games. If that continues, San Francisco will face pressure to upgrade. Eldridge has begun working on outfield positioning, but the Giants have been explicit that they will not rush him defensively.
The Giants' org coefficient in the CUP model is not high. They have a history of measured development over aggressive promotion. The Posey comparison is instructive: he waited until late May of his second professional season before his second MLB stint. Eldridge may follow the same path.
An injury to Devers or a collapse in the outfield production that goes unaddressed are the two accelerants. The Giants need Eldridge to continue walking at an elite rate while posting the power numbers that match his raw tools. If his OPS stays above .950 and the big league offense does not improve, the organizational patience will be tested.
The model gives the promotion window as May to July. Pathway C, performance-driven. The org coefficient suppresses the probability. The bat makes it live.
