We have no directly Astros-related birthdays today that I could find, so I will leave you with a tangentially Astros-related birthday.
Louis Victor "Sweet Lou" Piniella (68)
Born in Tampa, FL, Lou roamed the outfield for the Kansas City Royals from 1969 to 1973 and for the New York Yankees from 1974 to 1984, collecting a AL Rookie of the Year title, 5 AL East titles, 4 AL penants and 2 World Series championships along the way.
But most Astros fans probably remember Lou more for his years as a manager, particularly his stint with the Cubs from 2007 to 2010 and particularly for his colorful ejections from games. What he wasn't able to accomplish in sheer numbers (Bobby Cox has him beat there), he was certainly able to make up for with style points. (I personally wouldn't mind a little more fire from the Astros dugout.)
After managing 3548 games for 5 teams over a span of 23 years for a .517 win percentage, Piniella retired in 2010 to take care of his ailing mother. Sweet Lou, indeed.
