Craig Andrew Breslow (born August 8, 1980, in New Haven, Connecticut) is a Major League Baseball relief pitcher for the Oakland Athletics. He throws left-handed, and is considered a lefty specialist. Through 2008, he held major league batters to a .163 batting average with runners in scoring position (and .116 with two outs and runners in scoring position), and lefties hit only .188 against him, with a .256 slugging percentage. Breslow was given the nickname "smartest man in baseball" by Minneapolis Star Tribune Twins beat writer La Velle E. Neal. Breslow attended Trumbull High School in Trumbull, Connecticut, graduating in 1998, and was a standout in soccer and baseball. When Breslow was 12 years old, his sister Lesley—two years older—was diagnosed with pediatric thyroid cancer. This experience led Breslow to take an interest in molecular biophysics and biochemistry. Later in life, Breslow formed a non-profit foundation to help children with cancer.
