Bat Review: 2018 Marucci F5 Baseball Bat

Bat Review: 2018 Marucci F5 Baseball Bat

In March 2017, Marucci filed for a new trademark: F5.

Was it a computer keyboard key? A Battleship move? An aircraft? Or, could it be, Marucci is taking another step to revolutionize the game?

On August 1, 2017, Marucci officially releases their new baseball bat lineup. The F5 series will include a BBCOR, Senior League, and Junior Big Barrel model. The lineup is complementary to the highly-regarded CAT lineup, which includes the Marucci CAT 7.
Marucci named the CAT series after hurricane categories, due to the sheer strength the AZ4X alloy brought to the bats. Now, Marucci has opted for a series name that also references a disastrous weather phenomenon. The F5, named after the type of tornado that generates wind speeds of 200 mph or greater. And, the F5 bats promise to generate power sans the devastating effects of a tornado.
