David Price said goodbye to one of his closest companions and biggest fans Wednesday.

In posts on social media, the Red Sox pitcher announced that Astro, the fan-favorite French bulldog he has had since his early years as an MLB player in Tampa Bay, had died.

“I knew this day was coming sooner rather than later but it still hurts the same,” Price wrote on Twitter. “Astro took his last nap today and we will miss him dearly!”

Price thanked fans for constantly checking in and asking about Astro, who had become something of a social media star. He also posted several of his favorite videos and photos of Astro on Instagram.
