Contreras, 25, got married Thursday in Chicago, but only after postponing the nuptials twice due to rainouts the past month.
"I think everyone was surprised because I didn't tell anyone," Contreras said Sunday. "It got canceled twice because of the rain delays and stuff. I didn't want to talk about it until it happened."
The Cubs had five postponements in early April, twice playing games on originally scheduled days off. It messed with the continuity of their play as well as Contreras' marriage plans.
"I did not know that," manager Joe Maddon said when informed of the news. "I owe him a gift."
Eventually, word got around, and Contreras got his congratulations.
"He asked, 'Willson, did you get married?'" the catcher said of Maddon. "Then he gave me a hug."
After being informed of the news, Maddon deadpanned: "I'm glad I played him today."
It didn't work.
Contreras went 1-for-6 with a run scored and two strikeouts. He is hitting .231 but is batting just .100 with runners in scoring position.
