Seattle showed its backbone on Sunday, scoring two late runs to take two of three from Houston. The Mariners turn to SP Luis Castillo on Monday against a Twins club that lost 9-2 Sunday, as Boston snapped their 12-game winning streak. Castillo has pitched very well in his last four appearances (four earned runs with 31 strikeouts in 26 combined innings) and faces a Minnesota team that has a .300 OBP at home and a .310 OBP vs. right-handers.

Twins SP Simeon Woods Richardson hasn't faced stiff competition (Detroit once and the White Sox twice) and put nine runners on base in 3.2 innings in his last start. The Mariners have enough working in their favor to win this game as slight favorites on the road.
