The Oakland A's agreed to a long-term deal with reliever Sean Doolittle. This contract extension is for five years, and it expires in 2018. There are also team options for 2019 and 2020 included. His previous contract was a one-year deal worth $505,000 in the majors and $295,500 in the minors.

Doolittle converted from first base in the 2011 season, according to USA Today. He has emerged as a reliable relief pitcher for the A's since.

Doolittle has a 7-6 record with a 3.10 earned run average in his career, and he also has 129 strikeouts. He has made 122 relief appearances with the A's. He has thrown accurately too, walking only 24 batters. He has one save to go with a 3.12 earned run average so far this season.

The A's are expected to consider moving forward with him as their closer, according to NBC Sports. Current closer Jim Johnson has struggled so far in the 2014 season.
