Octavio Dotel will decline the Rockies' offer of arbitration, according to Jon Heyman of SI.com (on Twitter). The Rockies will obtain a supplementary first round pick in next year's draft for losing the Type B free agent as long as he signs a major league deal with another team.
The 37-year-old pitched for three clubs in 2010, posting a 4.08 ERA with 10.5 K/9 and 4.5 BB/9 in 64 total innings. Dotel saved 21 games for the Pirates before being dealt to the Dodgers and Rockies. MLBTR's Tim Dierkes suggested in June that Dotel may pursue a deal like the one he signed with the White Sox: $11MM for two years.
