SEATTLE (AP) — Nolan Arenado hit a sacrifice fly for his 110th RBI of the season, Colorado scored a pair of runs on Kyle Seager's throwing error and the Rockies beat the Seattle Mariners 3-2 on Sunday.

Arenado, the National League leader in RBIs, capped a third inning when the Rockies scored without a base hit. Charlie Blackmon walked, advanced to second on a groundout, stole third and scored on Arenado's fly ball to deep right field. The Rockies added two more an inning later when Willin Rosario doubled leading off, Justin Morneau walked. Both scored when Seager overthrew catcher Steven Baron trying to cut down Rosario at the plate after Dustin Garneau hit a weak groundball to third. It was the 16th error of the season for Seager.

Kyle Kendrick (6-12) allowed two runs over five innings to pick up his second straight victory.
