“I said I couldn’t go back into the season expecting to be the same role, same results, or being even better, with the same slider,” Treinen said. After signing a two-year contract to remain with the Dodgers, Treinen debuted the variation during the third week of spring training in Arizona. In 2020, his slider generated a 35.8% whiff rate and 21.8% put-away rate, according to BaseballSavant.com. Last season, Treinen said, he sought weak contact. This season, he’s better at keeping the ball out of play and minimizing the potential for trouble.
