Kansas City, Mo. ? Nick Blackburn shook off a slow start and pitched five effective innings, helping the Minnesota Twins beat the Kansas City Royals 4-2 on Wednesday night.

Justin Morneau hit a go-ahead, two-run single with two out in the fifth as Minnesota won for the fourth time in five games. Morneau, Ben Revere and Ryan Doumit each had two hits.

Blackburn (2-4), who was making his first start since coming off the disabled list following a left quad strain, allowed two runs and five hits. He threw 92 pitches while lowering his ERA from 8.37 to 7.75.

Yuniesky Betancourt hit a two-run homer in the first, but that was it for the Royals. Four Twins relievers combined for four innings of two-hit ball, with Matt Capps tossing a perfect ninth to log his 14th save in 15 opportunities.

Royals right-hander Felipe Paulino faced four batters in the first inning before leaving with a strained right groin. Paulino was injured on his 13th and final pitch, retiring Morneau on a fly ball. He will be evaluated in the next few days.
