Houston Astros Fan's Gnarly Finger Injury Photos In T-Shirt Cannon Incident

TMZ Sports has obtained pictures of the injury a Houston Astros fan allegedly suffered when the team's mascot "shattered" her finger with a t-shirt cannon last summer ... and they're gnarly.

A woman claims she was at a 'Stros game last July 8 when Orbit -- Houston's furry mascot -- fired t-shirts at her and her family at a rapid pace from his "bazooka style T-shirt cannon."

The woman -- who filed a lawsuit against the team for the incident this week -- says one of the t-shirts caught her square in the hand ... and mangled her left index finger.

You can see in the photos, her digit was severely swollen and bruised ... and needed TWO screws to help stabilize it.

In her lawsuit, the woman says she had to have multiple surgeries to fix the issue ... and claims she still has little range of motion in the finger.

Now, she's suing the team for $1 million ... saying the team failed miserably to protect its fans.
