Home-plate umpire D.J. Reyburn issued warnings to both dugouts and after the Cubs' 5-1 win over the D-backs, Montero said the pitch looked as though it were on purpose.
"Well, obviously two outs, nobody on, down by four and he throws it like that to me?" Montero said at the time. "It's a little shady, you know. Don't you agree? I don't know what it's all about."
Turns out, it was all a big misunderstanding.
"It wasn't on purpose," Strop said. "I was trying to come in. I just pulled that ball too much. I think he was kind of surprised. He gave me a dirty look and I just gave it back to him."
When told Tuesday what Strop said, Montero seemed to accept the explanation and it did not appear that the incident would carry over.
"We're in a battle right there -- he's fighting for his team, and I'm fighting for my team," Strop said. "He thought it was on purpose and he gave me that look and I gave it back. I think it's over -- hopefully, it's over. We don't want to get in a fight or anything like that. We just want to play the game the way we're supposed to play it."
