Justin Turner, since at least 2019, has been swinging the Louisville Slugger T181. According to our article on the Top 5 Endloaded Bats of the 2020 World Series:
The T181 features a long, large barrel most similar to the C243 turn model (available at Baseball Express). The thin handle is met by a uniquely flared knob for added comfort and whip. The model is recommended for those who like a significant barrel feel. The T181 is not available online, but Sam Bat sells a similar model called the TY’S available for purchase on SamBat.com for $150.
If you’re committed to Slugger, get the similar C243 at Slugger.com for $85.
