With two outs and the bases empty in the ninth inning on Sunday, D-backs closer Greg Holland threw a fastball behind Padres catcher Francisco Mejía.

Then he did it again.

Mejia struck out four pitches later to cap an 8-4 D-backs victory. But the end of the ballgame -- which was relatively tame, otherwise -- might not have marked the end of those proceedings.

Holland pleaded innocent afterward, but Padres skipper Andy Green was having none of it. He felt as though the pitches carried some purpose.

In San Diego's victory on Saturday, Robert Stock came inside on David Peralta before Trey Wingenter plunked Eduardo Escobar in the left kneecap two batters later.

A day later, when Holland came inside on Mejia, the Padres' rookie catcher merely backed away with a knowing shrug. But San Diego's dugout took exception. Green barked loudly at home-plate umpire Mike Winters. Afterward, he voiced his displeasure again.
