★★★Deacon JamesIt’s an okay place…it gets the job done when you need reps. The cages are always off, a lot of bad pitches being thrown way outside of the strike zone. We have been coming here for 5 years now, but once you go to D-Bat 🤷🏼♂️. My travel ball player just turned 12, and gets mad at me for wanting to come here. It is way closer to us vs. D-Bat, and we still have about 50 coins to use. He just doesn’t want to come back. Not going to waste the coins, so he can just get in the reps when I can convince him to come here. Also, there are teams that show up on a Saturday/Sunday with 8+ players, they don’t rent out a private space, and you just have to stand in line behind them. Poor management, allowing them to do that. Make them rent out a tunnel, when an entire team is coming in.
★★★★★Jimi VanderpoolGreat indoor batting and pitching cages - and even better staff. Prices are reasonable and quality of borrowable gear is decent enough.
★★★★★T MMy girls have been going here for training for 2 years. They have developed so much just in that minimal amount of time. The owners are amazing, and they truly care about the kids. I love supporting them because of the loyalty they have shown my family. Such an amazing small business.
★★★★★Ryan McMurrayThey provide quality instruction from qualified trainers. Plenty of cages to work in plus they have automatic indoor batting cages.
★★★★★Brad GossardWe had a fantastic experience at Mannino’s Grand Slam USA in Dublin! The staff was so incredibly nice and welcoming from the moment we arrived. The facility is very clean, well-kept, and comfortable, which really made the whole visit enjoyable. Most importantly, the kids had an absolute blast — they were all smiles the entire time. It’s clear this place is run with care and attention to detail. Highly recommend for families looking for a fun and positive outing!
