On Monday afternoon Pittsburgh Pirates All-Star closer Jason Grilli 1.) pitched an inning in a rehab start with the Class AA Altoona Curve and 2.) made hundreds of fans for life.

"Just across the board class act" Curve General Manager Rob Egan told the Altoona Mirror.

"Definitely a very classy individual" Curve fan Tim Pittsley said.

What did Grilli do to earn this praise?

After the 36-year-old veteran pitched the first inning he walked up to the Altoona stadium's concourse area sat down at a picnic table and spent more than an hour signing autographs and posing for pictures for several hundred fans. The team says he did it on his own.

"I know there's a lot of fans that came out to support me and want me back in Pittsburgh so it's just a way to pay back dividends to the fans" Grilli told the Mirror.

The newspaper described Grilli's actions as "nothing short of stunning and unprecedented" at the Altoona ballpark.

After major league pitchers are done for the day in a minor league rehab assignment usually "they go in and take a shower get dressed and leave the ballpark before the game is finished" according to the newspaper.

Not Grilli a well-traveled journeyman who is having the best season of his 11-year big league career.
