Spence pitched for Australia in the 2006 World Junior Championship and then came to the USA for junior college. In 2007, he was 13-3 with two saves and a 1.10 ERA for Central Arizona College and was named an All-American and Arizona Community College Athletic Conference Player of the Year. As a sophomore, he went 14-4 with 7 saves and a 1.69 ERA, again being named All-American and his Conference's Player of the Year. His team finished third at the 2008 NJCAA Division I Baseball World Series. The Arizona Diamondbacks took him in the 25th round of the 2008 amateur draft but he did not sign.
In 2009, Spence moved on to Arizona State University and went 10-1 with a 2.37 ERA in 18 games as a junior, striking out 125 batters in 102 2/3 innings of work despite missing over a month due to injury. He was named third-team All-American and first-team All-Pacific-10 Conference. In the 2009 College World Series, he fanned 16 in 14 innings including a win over the University of North Carolina. He was drafted by the Los Angeles Angels in the third round of the 2009 amateur draft and offered a $240,000 but he opted to return for his senior year to complete his degrees in sociology and education. He did not pitch in college in 2010 and was picked by the Padres in the ninth round of the 2010 amateur draft. He was signed by scout Dave Lottsfeldt for a $100,000 bonus.
Spence began his pro career with the Eugene Emeralds and allowed one run in six innings before moving up the ranks.

After starting 2011 with a 3-1 record and a 1.71 ERA in 35 relief appearances for the San Antonio Missions, he was called up by the Padres. He made his big league debut against the Atlanta Braves on June 24th, throwing a scorelless inning of relief.
