Diamond Prospects Team Leaders
Each Diamond Prospects scale is ranked on its own: hitter grades (DBH), starting-pitcher grades (DPG SP) and relief-pitcher grades (DPG RP) share no common scale, and are never compared with one another. WAR is a single scale across roles, so the historical and projected WAR leaders list hitters and pitchers together.

DPG — Starting Pitchers

DPG — Relief Pitchers

Team Statistical Dashboard
Aggregates are computed from the stored 2026 season records of the 21 players whose 2026 season is recorded with this club alone. They are partial-coverage club figures, not official MLB club totals, and every block states how many players it covers.

OBP and OPS are not shown at club level: hit-by-pitch and sacrifice flies are not in the stored inputs, so an exact club OBP cannot be computed, and averaging player rates would be invalid. Player OPS and wRC+ are listed in the advanced metrics below.

Innings are stored in baseball notation (.1 = one out, .2 = two outs), so the club total is summed as outs and written back in that notation. SIERA, FIP− and K−BB% are rate statistics and are never averaged into a club figure — they are listed as stored player values below.
Additive stored measures
fWAR, OAA and DRS are additive, so a covered-player sum is a defensible club figure. Each sum states exactly how many players supplied a stored value — a player with no stored value is never counted as zero.
fWAR (2026)

21 of 21 covered players with stored fWAR · batting + pitching added
WAR (2026, as reported)

OAA (2026)

3 of 21 covered players with a stored OAA
DRS (2026)
72
6 of 21 covered players with a stored DRS
BOS defensive metrics are stored for a smaller set of players than the batting and pitching feeds, so the OAA and DRS sums cover fewer players than the fWAR sum. The coverage line on each tile is the number that matters.
Advanced Metrics — Stored Player Values
No club-level rate is calculated here. Each metric is shown as the stored 2026 value on each BOS player's record, with the coverage stated, so a club figure is never implied by an average of unlike players.

Positional Makeup
The stored primary positions on BOS player records, and the defensive innings from the stored 2026 positional profiles. A position is never inferred — a player with no stored position is counted in neither block.
Stored primary positions
2026 defensive innings by position
Summed from the 7 players of this club who have a stored 2026 positional profile, so this is a partial innings picture and not a club defensive total.
Projected WAR Contributors
Stored Diamond Projections for the BOS players whose stored club association is this club. A projected season is provisional model output for a future year and is never blended with an actual result.

Σ over 20 players
The total above covers only the players who both carry a stored BOS association and have a stored 2027 projection. It is a covered-player contribution total, not a complete team forecast: the stored dataset is not a full roster, players without a projection are absent, playing time is not modelled, and coverage differs from club to club — so these totals are not comparable between clubs and are not a projected club ranking.

Data coverage, not a current roster. The stored dataset covers the completed 2026 season, so every association on this page is labelled by that season. No current-roster source is connected to this app, so nothing here is presented as a verified current 26-man or 40-man roster, and no player-team assignment is ever invented, inferred or back-filled.
How a player is listed. A player appears on Boston Red Sox when either stored record places him there: the club stored on his player master record, or a 2026 season appearance recorded with this club. Each row states its own 2026 appearance record, so a traded player's split season ("Club A / Club B") is visible rather than hidden. Players whose stored association is a minor-league or international club are shown with that stored value — it is never relabelled as BOS. A handful of players carry no club association at all and are listed on no club page.
Club aggregates exclude split seasons. A player whose 2026 season is recorded with more than one club is listed, labelled and left out of this club's 2026 aggregates and 2026 WAR leaders, because his season totals cannot be attributed to one club. This club has 21 contributing single-club players out of 27 associated players, and 6 members carry a split 2026 season. A figure that is not stored is shown as Not Available and is never treated as zero.

DBH, DPG (starters) and DPG (relievers) are three separate scales and are never merged into one ranking. Grades, historical WAR and percentiles are shown exactly as stored — no Diamond Prospects formula, frozen grade or projection is modified by this page. D$V, market value and contract valuation research are out of scope here and are not read or displayed.
