"I felt like I was safe. I don't ever argue with the umpire," Desmond said. "But I was pretty [convinced] that I was safe on that one."
Williams talked to first-base umpire Marvin Hudson and challenged the call at first. After a review of two minutes and 15 seconds, the umpires ruled that the play would stand as called.
"He looked safe to me. Ian thought he was safe," Williams said. "[First-base coach] Tony [Tarasco] thought he was safe. So at that point [it would have been] bases loaded, potentially, there. That's potentially a huge inning for us. So I went out and challenged it. It didn't go our way, but you have to go for it."
Desmond ended up hitting the game-winning home run against Wood in the seventh inning.
