Ian Drew Thomas (born April 20, 1987) is an American former professional baseball pitcher.

He played in Major League Baseball (MLB) for the Atlanta Braves and Los Angeles Dodgers.

[2] In 2010, he was the Northern League Rookie Pitcher of the Year, after going 5–1 with a 1.64 earned run average (ERA).

However, due to a rash of injuries to Braves' pitchers and an impressive Spring training run, Thomas was one of the final two players (along with fellow left-handed reliever Ryan Buchter) named to the Atlanta Braves' Opening Day roster.

On May 4, 2014, Thomas was optioned to Triple-A Gwinnett to make room for Gavin Floyd, who was activated off the disabled list.

He was designated for assignment by the Dodgers on June 30, 2016, to make room for newly acquired pitcher, Bud Norris[18] and released a few days later, on July 3.
