"I felt we put up some good at-bats, the type of at-bats where you wouldn't expect a zero to be up there," Cleveland manager Eric Wedge said. "But that's the way it played out."
Blackburn (1-1), who hit one batter and gave up eight hits without a walk, earned his first major league win with veteran poise by using the defense behind him to escape a couple of jams.
He used his sinker to induce four inning-ending double-play grounders, including two by David Dellucci.
"There were so many ridiculous plays," said Blackburn, who started one himself with a leaping stab of Asdrubal Cabrera's up-the-middle bouncer in the fifth.
Morneau took Jake Westbrook (1-2) deep with two outs in the first inning for his fifth homer and a 2-0 lead, the beginning of a sound formula for victory over a struggling team.
The defending AL Central champions have a league-low .239 average, and designated hitter Travis Hafner -- despite 12 RBIs -- dropped to .227 with an 0-for-4 afternoon that included a double play and a strikeout.
"I think we're moving in the right direction," Westbrook said. "We just need to continue to try to be more consistent. We're up and down in different areas. Right now the offense is struggling a little bit. I definitely didn't come out strong."
Following up a two-hit, no-run, eight-inning performance by Cliff Lee the night before, Westbrook actually turned in another solid start. Reigning Cy Young Award winner C.C. Sabathia is having a terrible time this month, but the middle of the rotation -- Fausto Carmona included -- has ably picked up the slack.
Westbrook walked one and struck out four, surrendering eight hits and those three runs in seven innings. After Morneau's home run, which cleared the tall right-field wall by a few inches, Westbrook had three 1-2-3 innings and retired 11 of 12 in one stretch. Carlos Gomez's two-out single down the left-field line in the second inning was the only other damage done.
"As good as our kid pitched, I still felt like we could've done a better job offensively to try to create something or at least put an inning together," Wedge said.
The Twins have been quite pleased with their starting pitching, despite Francisco Liriano's trouble. Blackburn made the rotation because Liriano needed more time in the minors, but with a 2.49 ERA and 25 1/3 innings in four starts he'll be hard to move out of the rotation.
"It doesn't look like he gets rattled too much," manager Ron Gardenhire said, adding: "We liked him last year, and I think his progression is getting better and better."
It helps to have good glovework in the field.
Shortstop Nick Punto, playing in place of the injured Adam Everett, was the pivot man on all four double plays. Morneau did a pretty good job of stretching for those second outs at first base himself, and he made a hockey-goalie glove save of Dellucci's hot chop in the seventh to start the fourth double play.
Also, a perfect throw by left fielder Delmon Young helped preserve the shutout. Casey Blake singled in the third, but Cabrera was out at the plate trying to score from second when the ball one-hopped to catcher Joe Mauer's glove.
Now, the Twins must find a way to hit a few balls a little further. Jason Kubel, who has three home runs, is the only other player beside Morneau who has homered in 18 games this season. Minnesota entered the game with a .348 slugging percentage, lowest in the league.
If the other guys don't get their power stroke going, well, Morneau is usually good for it.
"Just trying to find a way to help us win. That's it," he said.
Mauer turned 25 on Saturday. ... The Indians, who went 14-4 against the Twins last season, had an eight-game winning streak against Minnesota end. ... Hafner, who has a sore right shoulder, will probably be out of the lineup to rest on Sunday and get two days off with a scheduled off-day on Monday. ... Westbrook is 1-7 in his career against the Twins. ... Jamey Carroll, emerging as a regular at 2B, got on base only once but has still reached in 11 of his last 19 plate appearance.
