Sources — Royals keeping Seth Lugo on multiyear extension

Right-hander Seth Lugo and the Kansas City Royals are finalizing a multiyear contract extension, sources told ESPN’s Jeff Passan on Sunday.

Lugo, 35, had been regarded as one of the best potential trade candidates this deadline season and one of the top free agent arms this winter.

Lugo has posted ERAs of 3.60 or lower for the past five seasons despite having below-average fastball velocity and good but not great strikeout rates. The right-hander’s ability to strand runners and limit hard contact comes in part due to his nine different pitches, which give him the flexibility to to make in-game adjustments, a luxury shared by only a handful of MLB starters.

Lugo is 7-5 with a 2.95 ERA and has 99 strikeouts in 113 innings.
