Pronine PM9 Dimpled Pitching Machine Baseball 9"

The ProNine PM9 Dimpled Pitching Machine Baseball is the go-to ball for heavy-duty, high-volume machine work. Molded from solid polyurethane with a dimpled optic-yellow cover, it delivers unbelievable durability rep after rep and is compression-controlled so it won't dent your bats — the dependable choice for programs that put thousands of pitches through the machine every season. Because it's molded rather than stitched, there are no seams to fray, so it keeps its shape and flight far longer than a leather ball under machine use.

Key features & specs:

• Size/weight: official 9 inch, 5 oz
• Cover/core: dimpled solid polyurethane construction
• Performance: .47 COR, compression controlled to 375 lb max
• Durability: built for relentless high-volume machine reps
• Bat-safe: specifically designed not to dent bats
• Color: optic yellow for high visibility; sold per dozen

Coach's tip: the PM9 is your everyday machine ball — save leather for game-feel days and let these absorb the volume. Rinse off dirt with water, air-dry, and store in a ball bucket out of extreme heat to maximize its long service life.
