The asking prices for most free-agent starters have not appealed to the Padres. On Tuesday, they demonstrated it by purchasing controllable right-hander Bryan Mitchell from the New York Yankees. San Diego agreed to take on third baseman Chase Headley and his $13 million salary in the trade. On Sunday, the Padres re-signed right-hander Jordan Lyles to a one-year contract worth $1 million. Lyles will make $750,000 in 2018. The deal includes a club option (with a $250,000 buyout) and performance bonuses for 2019. Left-hander Travis Wood was designated for assignment, clearing room for Lyles on the 40-man roster. Once an interesting prospect, Lyles signed a minor league deal in August after being released by the Colorado Rockies. He had his contract purchased and struggled to a 9.39 ERA in five starts with San Diego. Lyles, 27, was an unusually young free agent this winter. He debuted in the majors as a 20-year-old, showed early promise in Houston’s rotation and has since failed to gain traction.
