The Miami Marlins All-Star who was beaned by a fastball last week prompting fears of a career-ending injury, posted graphic before and after photos on Instagram Tuesday and said he "is making huge progress."

Giancarlo Stanton, the MVP candidate who was hospitalized Thursday after getting hit by the 88-mph fastball, took to Instagram to thank fans for the "kind message, thoughts & prayers" during his recovery.

Stanton sustained multiple facial fractures, dental damage and cuts that needed stitches.

The pitch was high and tight and Stanton was seen opening his hips to swing while the ball hit him square in the face.

Marlins manager Mike Redmond said at the time Stanton, the major league RBI leader, is likely done for the season. Brewers catcher Jonathan Lucroy said the pitcher was trying to get a fastball up to Stanton.

"(Mike Fiers) gets a lot of (strikeouts) on fastballs up, and the ball just got away from him," he said. "You saw what happened. It was definitely a scary moment. You never wish that on anybody. It's just a freak accident."
