Upton announced the pregnancy on Instagram on Saturday in a post with the hashtag "pregnant in Miami" where she tagged Verlander. The picture of her in a red, high-waisted suit and white top revealed a slight baby bump.
Verlander, who was selected to his seventh All-Star Game on Sunday, shared her post later Saturday with the caption: "You're going to be the most amazing Mom!! I can't wait to start this new journey with you! You're the most thoughtful, loving, caring, and strong woman I've ever met! I'm so proud that our little one is going to be raised in this world by a woman like you! I love you so much."
The 26-year-old Upton and 35-year-old Verlander were married Nov. 4 in Italy, just after Verlander helped the Astros to their first World Series championship.
