Thompson, a native of Australia, had some success in 2011 with the Angels, acquitting himself nicely in 44 relief appearances, compiling a 3.00 ERA in 54 innings. He went 1-3 with 56 strikeouts, 20 walks, and a 1.22 WHIP. He appeared in two games for the A's this year, surrendering four earned runs on five hits, striking out three and walking one before being DFA'd after only 2.1 innings of action.
The 27-year old broke into American baseball as an undrafted rookie back in 2002, signing on to play with the Angels. He played in his first big league game in 2007, and has seen very limited action in the Majors since then. He was also a part of the 2004 Australian national team that grabbed a silver medal in the Athens Olympics that year.
According to the A's, the roster move will go through as soon as Thompson reports to their facilities.
