As the sample sizes grow and teams pass the halfway point of the season, it helps break down performance in monthly splits. Using underlying metrics and hard statistical data, some intriguing names emerge in the June leaderboards with the Trade Deadline fast approaching.
League Saves through June
- 2025: 632 saves
- 2024: 639 saves
- 2023: 636 saves
Blown saves through June
- 2025: 369
- 2024: 367
- 2023: 361
Save Opportunities through June
- 2025: 1,001
- 2024: 1,006
- 2023: 997
No matter how the relievers and team approaches change, the numbers remain consistent across the last three years. With this in mind, here are the save trends by individual relievers since 2023:

Last year, Ryan Helsley (30) and Emmanuel Clase (25) had more than 24 saves, but they are the only two since 2023 to accomplish this feat.
Individual Results and Trends from June 2025
Mining the data from qualified relievers only in June, there were some relievers of interest, and some strong performances by relievers on the trade deadline radar. Beginning with the top performers by my four favorite categories, these relievers met the standards for all four of the following:
K-BB percentage greater than 20 percent, a swinging strike rate above 16 percent, a strike percentage over 66 percent, and a contact rate allowed below 66 percent:
| Name | K-BB% | SwStr% | Strike% | Contact% |
| Aroldis Chapman | 45.9% | 26.3% | 73.0% | 57.9% |
| Josh Hader | 42.9% | 23.9% | 68.7% | 58.3% |
| Griffin Jax | 40.0% | 26.0% | 68.5% | 49.3% |
| Devin Williams | 33.3% | 20.4% | 67.3% | 60.5% |
| Bennett Sousa | 31.7% | 20.5% | 70.9% | 64.8% |
| Jason Adam | 23.4% | 19.3% | 68.5% | 62.9% |
| Reid Detmers | 23.1% | 16.5% | 68.9% | 65.7% |
- Aroldis Chapman will be a topic of debate. He’s signed to a one-year contract, and while his team maintains it’s going to finish better than last year, does keeping the potentially highly sought-after southpaw on the roster past the trade deadline make sense?
- Devin Williams has taken a complete 180 from his rough start in New York. He’s a pending free agent and will continue adding to his allure this winter.
These relievers missed the cut but qualified in three of the four categorical requirements listed above:
| Name | K-BB% | SwStr% | Strike% | Contact% |
| Bryan Abreu | 39.6% | 23.1% | 61.5% | 50.9% |
| David Bednar | 36.1% | 16.7% | 66.7% | 66.7% |
| Edwin Uceta | 34.6% | 20.9% | 64.0% | 58.9% |
| Edwin Diaz | 33.3% | 18.8% | 63.2% | 62.5% |
| Shelby Miller | 33.3% | 16.9% | 71.1% | 66.7% |
| Braydon Fisher | 32.7% | 15.0% | 66.8% | 65.0% |
| Dylan Lee | 31.8% | 17.2% | 71.2% | 68.5% |
| Will Vest | 29.3% | 16.5% | 68.8% | 67.4% |
| Nick Mears | 26.8% | 16.1% | 72.5% | 71.1% |
| Jeffrey Springs | 25.5% | 16.2% | 68.6% | 69.0% |
| Raisel Iglesias | 22.0% | 15.8% | 68.5% | 65.7% |
| Mason Montgomery | 22.0% | 19.3% | 67.6% | 66.1% |
- Bryan Abreu had a tremendous June and has been valuable as a ratio eraser despite not getting a save, finishing 25th in SGP.
- Will this be the year David Bednar gets traded? I have advised against this in years past, but this year, the Pirates should be selling him and Dennis Santana.
- Speaking of potential trade bait, Shelby Miller had a strong June. This was the iteration I was expecting last year, but I digress. If Arizona drifts further in the standings, Miller, on an expiring contract, should be moved.
