Detroit ? As good as Rick Porcello was on Tuesday night, Tigers manager Jim Leyland thinks he can do better.

Porcello allowed two hits over seven shutout innings and Ryan Raburn homered to lead Detroit to its fifth straight win, 9-1 over the Kansas City Royals, on Tuesday night.

Porcello retired the first 12 batters he faced before Billy Butler singled leading off the fifth inning. Porcello then retired the next three batters. He walked one and struck out four.

“He changed the planes. He threw strikes. He was good. He got the ball on the ground,” Leyland said. “Was he great? No. But he was good.”

Porcello said it wasn’t a big deal when his shot at a no-hitter was broken up.

“It’s only the fifth inning, still a long ways to go for that,” Porcello said. “I wasn’t really disappointed, just kind of keep pitching and keep them off the board.”

Kansas City second baseman Chris Getz was impressed with the outing.

“He wasn’t giving us much, just had good command,” Getz said.

Porcello has struggled this season — his ERA is 5.43 and he was sent to the minors for a short time — after going 14-9 with a 3.96 ERA in 2009 as a rookie.

“It’s good to see him getting back to his old self and what he’s capable of,” Detroit third baseman Brandon Inge said. “We need him bad.”

Inge explained why Porcello was successful.

“Getting strike one,” Inge said. “He get so much movement, if he gets strike one, he can be so goo.”

Kila Ka’aihue homered for Kansas City, which was held to three hits.

Royals’ starter Kyle Davies (6-8) gave up seven runs on 12 hits in 4 2/3 innings, walking three and striking out five.
