Former MLB pitcher Tommy Hanson dies at 29

Tommy Hanson, a former MLB pitcher who spent most of his career with the Atlanta Braves, died Monday night due to "catastrophic organ failure." He was 29 years old. Reports say Hanson was having trouble breathing Sunday morning and was taken to Piedmont Hospital in Atlanta, where he later fell into a coma. The cause of the organ failure remains unclear.

Hanson began his career as a starting pitcher for the Braves in 2009, where he posted a 2.89 ERA over 21 starts and was third in the National League's Rookie of the Year vote. He went on to two more strong seasons before injuring his shoulder, and was traded to the Los Angeles Angels in 2012. Though away from the team for several weeks after the death of his younger stepbrother, Hanson made 13 starts for the Angels in 2013, and made his final major league appearance on September 28 of that year.

Hanson signed briefly with the Texas Rangers and the Chicago White Sox in 2014, and played in the minors before becoming a free agent. He signed a minor league deal with the San Francisco Giants in May 2015. In his five-season career, Hanson went 49-35 with a 3.80 ERA.

Former teammates and opponents took to Twitter to mourn Hanson's loss this morning, calling him "a great guy and competitor."
