TCU once again paced the league with 97 stolen bases.
A group of familiar faces in 2017 led to a preseason No. 1 ranking. The group lived up to its billing, reaching the CWS for the fourth straight year. Once again, the Frogs scored runs at a high rate thanks to another 100-stolen base campaign (108), a mark that ranked seventh nationally, and 58 home runs. Additionally, TCU drew 354 walks to rank fourth nationally. Evan Skoug became TCU’s first 20 home run guy since the 1997 campaign en route to earning Big 12 Co-Player of the Year accolades.

Ten Frogs contributed to the 65 home runs. It’s the first time since 2011 that the Frogs have had 10 players with multiple home runs.
