PITTSBURGH — Rich Hill has agreed to a one-year contract with Pittsburgh, giving the Pirates another veteran arm for their rotation, according to a person familiar with the deal. The person spoke to The Associated Press on Tuesday on condition of anonymity because the club had not announced the signing. Hill, a Boston native who turns 43 in March, went 8-7 with a 4.27 ERA in 26 starts for the Red Sox this year. Hill joins a growing list of new faces with the Pirates. Carlos Santana, a first baseman and designated hitter, signed with the team in free agency, and first baseman Ji-Man Choi was acquired in a trade with Tampa Bay. Catcher Austin Hedges and right-hander Vince Velasquez also agreed to free agent contracts. Hill made his big league debut with the Chicago Cubs in 2005. Pittsburgh will be his 12th major league team. The 6-foot-5 left-hander, known for his curveball, is 82-59 with a 3.85 ERA in 350 career appearances, including 221 starts.
