The games
| Game | Grade | Favor | ABS | Blue Note |
|---|---|---|---|---|
| SEA @ TB2026-07-12 | A- | 0.6 TB | 2/4 | The kind of night where the umpire is the least of the story. |
| BAL @ LAD2026-06-21 | B+ | 1.2 LAD | 0/3 | One dugout got the friendlier version of the evening. |
| MIN @ TEX2026-06-15 | A+ | 0.1 TEX | 1/5 | If umpiring had a highlight reel, this wouldn't make it. That's the compliment. |
| DET @ TB2026-06-03 | A- | 0.1 DET | 2/4 | Squeezed the edges; the hitters didn't mind at all. |
| SD @ WSH2026-05-30 | B- | 0.0 WSH | 4/7 | A small strike zone, generously enforced for the offense. |
| NYM @ MIA2026-05-23 | A- | 0.4 NYM | 1/3 | Nothing that'll trend, and on this beat that's a compliment. |
| MIL @ CHC2026-05-18 | A | 0.3 MIL | 2/3 | Called it the way the rulebook drew it up. |
| LAA @ KC2026-04-25 | C+ | 0.4 KC | 1/5 | The zone shrank when the pitchers needed it most. |
| HOU @ CLE2026-04-21 | A | 0.3 HOU | 2/4 | An honest evening's grade: nothing loud, nothing missed by much. |
| MIL @ MIA2026-04-17 | A- | 0.7 MIA | 1/6 | Reliable as a Tuesday: no complaints, no headlines. |
| MIN @ TOR2026-04-12 | A+ | 0.7 TOR | 1/3 | Called a fair game and let the players decide it. |
| STL @ WSH2026-04-07 | B+ | 0.8 WSH | 1/5 | Down the middle. Both dugouts had the same zone. |
