Hill agreed to a one-year, $6 million contract with the A's on Tuesday, pending a physical, Jeff Passan of Yahoo! Sports reports.
The 35-year-old surprised everyone by allowing just five earned runs in four starts for Boston last season (29 innings), posting a 36:5 K:BB over the final couple weeks. If nothing else, he should prove a valuable innings-eater for Oakland next season, but ideally the team will be able to trade him if his success carries over to the first half. Hill owns a 4.54 ERA and 1.35 WHIP in 500 career innings at the major league level.
