Player of the Week:
Konnor Griffin (BRA) – Griffin broke out in a big way during his second week of professional baseball. Besides the offensive stats listed above, Griffin also made a phenomenal sliding stop at shortstop to save a run and keep the game tied. He's beginning to show the five-tool talents that made him so attractive to Pittsburgh in the first round of the 2024 draft.
This Week:
- Indianapolis Indians: vs. Toledo (Apr 15-20)
- Altoona Curve: vs. Somerset (Apr 15-20)
- Greensboro Grasshoppers: vs. Jersey Shore (Apr 15-20)
- Bradenton Marauders: @ Fort Myers (Apr 15-20)
