DeRosa is one of six current major league ballplayers to have attended an Ivy league school - the University of Pennsylvania - where he studied business.
[Unlike in hockey, most baseball players do go to university. Baseball players usually take longer to develop the skills they need to play at the highest level, and it's very rare to see an 18 or 19 year-old in the majors.]
DeRosa, 35, was originally drafted by the Atlanta Braves and has spent time on teams in Texas, Chicago, Cleveland and St. Louis. He was nicknamed "the Pulse" in 2008 after undergoing surgery to correct an irregular heartbeat.
Unfortunately, this fellow is taken. He is married to former model Heidi Miller. They have 2 children, Gabriella and Mark Jr.
But he's still fun to watch!
[Oh and by the way, A-Rod is still searching for that 600th homerun.]
