"With a man on third and [Pedro Alvarez] on deck, I felt it was a tough spot for him to make that call," Martin said. "I feel like I have a pretty good eye at the plate and should've been on first base, and it didn't happen that way.
"Nobody's perfect. I'm sure if [Hickox] looks back at the play, he'll probably think he missed that call. He did the best he could at that moment."
The player who caught that pitch agreed with Martin.
"No, I don't think it was a strike," said Brewers catcher Jonathan Lucroy. "But ... sometimes things go your way and sometimes they don't. Ed [Hickox] did a good job behind the plate today, he really did. It's just one of those crazy things that happens. Umpires are human beings, too, and they make mistakes."
It was Martin's first ejection of the season and Hurdle's second. Chris Stewart replaced Martin in the ninth behind the plate and bench coach Jeff Banister took over Hurdle's duties in the final inning.
The Pirates went on to drop the game, 1-0, and also lost the weekend series to first-place Milwaukee.
