Actually, if he was on the opening day roster next year, he would be a super 2, so it would go (I think):
2012: 500K
2013: 750K
2014: 900K (first arb year)
2015: 1M (second arb year)
2016: ?? (third arb year)
2017: ?? (fourth arb year)
2018: Free Agency
After 6 years of service time, you're automatically a free agent if you don't have a contract.
