Trey Mancini's mom went bonkers over his first MLB hit (it was a homer)

Baltimore Orioles first baseman Trey Mancini won't soon forget his first major league hit.

Neither will his mom, Beth.

Making his MLB debut, Mancini launched a home run into the left-center field stands in the fifth inning for his first hit.

His mom, who grew up an Orioles fan, acted appropriately (which is to say she freaked out):

Mancini's mom also got the keepsake ball a bit later.

As for Mancini, he said it also marked what would have been his grandfather's birthday, which made it extra special. His grandfather was an Orioles season ticket-holder for 20 years.

The only letdown? The Orioles lost to the Boston Red Sox, 5-2.
