The Nationals are signing Foster Griffin to a one-year, $5.5 million contact, according to FanSided’s Robert Murray.
He can make an extra $1 million in incentives. Griffin, 30, had a 1.62 ERA and a 77/18 K/BB in 78 innings as a starter for the Yomiuri Giants last season. A first-round pick of the Royals in 2014, he briefly pitched in the majors for Kansas City and Toronto before going to Japan in 2023. His velocity is well below average, but both his slider and cutter performed very well in the NPB. The Nationals will likely give him every opportunity to win a rotation spot.
