On the day Gio Gonzalez made his final start of the season's first half, he wandered about the clubhouse in a bright red T-shirt that proudly proclaimed "Strasburg Knows."

The Motown tunes were cranked up - "best music day of the week," bench coach Randy Knorr called it - and the Nationals' boisterous left-hander began to offer his usual greeting to anyone and everyone who made it into his sight line.

"With Gio all you have to do is grin and he's gonna be grinning at you," said Nationals manager Davey Johnson. "And he's gonna be hacked off at you if you're not grinning back at him."
