Isaac Paredes is an anomaly, so citing him is just a reach
Mears FB on the road - .296 xwOBA, .262 wOBA, 24.2% whiff rate, 19 IVB, 1.7 RV/100
Mears FB at home - .312 xwOBA, .309 wOBA, 14.5% whiff rate, 16 IVB, 0.6 RV/100
Meanwhile here is the gap in his breaking balls
Mears breaking balls on the road - .428 wOBA, .309 xwOBA, 34.8% whiff rate, -5.6 RV/100
Mears breaking balls at home - .249 wOBA, .178 xwOBA, 46.3% whiff rate, 0.8 RV/100
Just seems like focusing on the FB as the issue on the road was a miscalculation.
