Third base prospect Jacob Reimer will spend some time in camp this year as a non-roster invitee. Reimer enjoyed a breakout 2025 season where he hit .282/.379/.491 with 17 home runs and 77 RBIs split between High-A Brooklyn and Double-A Binghamton. His success saw him rise up the prospect rankings, with Amazin’ Avenue rank him seventh in the Mets system. MLB Pipeline has the 22-year-old ranked as the second best prospect in baseball at his position and Baseball Prospectus lists him as 70th in their top 100 prospect rankings.
The big righty won’t break camp with the major league team but Carlos Mendoza wants the top prospects to be around the major leaguers to learn from them and pick their brains as much as possible. As for Reimer he is using the opportunity to work on his bat speed and his defense according to The Athletic. Reimer still sees himself as a third baseman but with his build and athleticism he might be better suited for first base in the future.
Reimer played in 61 games at Double-A in 2025 and found some success after the promotion. He hit .279/.374/.479 with 9 home runs and 38 RBIs with the Rumble Ponies. He will most likely start the season in Double-A but he could continue to rise and see some time in Triple-A this season. He is a long shot to make it to the majors in 2026 but if there are enough injuries, he has an outside chance to get the call. This season it will be interesting to see if he is moved off third base and if the organization views him as their potential first baseman of the future.
