The Southern Maryland Blue Crabs are celebrating St. Patrick’s Day with the signing of former MLB pitcher Sean O’Sullivan.

“I am very grateful for the opportunity to get out there and compete for the Blue Crabs,” said O’Sullivan. “It means a lot to me joining on this day as well, coming from an Irish family. My grandparents were born in Ireland and a lot of my family still lives there today.”

The 30-year-old O’Sullivan comes to Southern Maryland with seven years of MLB experience under his belt. The right-hander was originally a third-round pick of the Los Angeles Angels in 2006 out of Grossmont College. O’Sullivan made an impact right away, going 4-0 with a 2.14 ERA in his first professional season, being named a Post-Season All-Star for the Orem Owlz.

The starter quickly worked his way up the ranks of the Angels organization, making his MLB debut in 2009 as a member of the Angels. His debut came on the road against the San Francisco Giants, where he fittingly picked up the win on Irish Heritage Night.

After 17 appearances for Los Angeles, O’Sullivan was traded to the Kansas City Royals in 2010. He spent the next two seasons with the Royals, before a two-year stint with the San Diego Padres, and finally a five-game stop with the Boston Red Sox in 2016.

“Sean’s experience at the highest level is invaluable to our pitching staff,” said Manager James Frisbie. “You always want guys like him in your rotation, consistently putting your team in a position to win games. And of course a little luck of the Irish never hurt anybody.”

Across his 12-year career, O’Sullivan has posted a 106-85 record, while appearing in over 300 games. He has pitched for seven different Major League organizations, most recently the Washington Nationals in 2017.
