    Great bat, love the end loaded feel, definitely gives the bat that added pop, and sounds great off the bat

    Bought this bat for my son's birthday and he loves it! Buster Posey is his favorite baseball player. The bat is very high quality and would recommend this bat to all of my friends!

    The turnaround time was great (to be honest it came faster than I hope). I've bought a standard Posey28 and it was great! My custom is the best bat I've ever had!!

    Posey28 Custom Pro

    Beautiful bat. Lots of pop and nice balance. Disappointed with the barrel size - is barely 2 1/8" so it's more like a softball bat. Not as expected.

What is a Smart-Ready Knob?

Marucci’s Smart Bat technology allows Diamond Kinetics’ SwingTracker sensor to be securely fitted inside of the actual knob of a Custom Pro Model bat. By selecting Smart-Ready knob, you’re authorizing Marucci’s wood production team to carve out part of the knob and install a dual-locking mechanism to firmly hold your SwingTracker sensor in place, allowing for the most accurate data possible.

Don’t forget the sensor!

The Diamond Kinetics SwingTracker sensor captures your most precise swing data using 11 different metrics in four core swing categories: speed, power, quickness, and control, then sends it to the SwingTracker app through a paired iOS device via Bluetooth. View metrics in easy-to-read graphics and charts or sync with a unique 3D image or video of your swing.
