"For him it's the mentality," Schu said. "It's in there, you just can't give at-bats away. [Last year] he's facing deGrom, in the shadows, throwing 98. He goes down 0-2, fouls some off, takes a couple pitches, fouls some off, it's a 10-pitch walk. If he has that mentality every at bat, the strikeouts will cut down."
