BALTIMORE (AP) - Brian Roberts hit a three-run homer, Jake Arrieta allowed one run in six innings and the unbeaten Baltimore Orioles thrilled a sellout crowd in their home opener by defeating the Detroit Tigers 5-1 Monday.
On a gorgeous afternoon at Camden Yards, the Orioles extended a surprising winning streak that began with a three-game sweep at Tampa Bay. Off to its best start since 1997, Baltimore (4-0) has not yet trailed, hasn't given up more than one run in a game and has outscored the competition 17-4.
With the score tied at 1 in the fifth, Felix Pie walked and went to third on a double by J.J. Hardy before Roberts hit a 1-2 pitch from Rick Porcello (0-1) over the wall in right-center. Roberts has Baltimore's only two home runs this season.
Nick Markakis followed with his third hit, a double, and Matt Wieters delivered a two-out RBI single for a 5-1 lead.
Arrieta (1-0) gave up six hits and walked two. Jason Berken followed with two innings of one-hit relief and Koji Uehara pitched the ninth.
Yankees 4, Twins 3
NEW YORK (AP) - Alex Rodriguez and Jorge Posada each hit a two-run homer, rookie Ivan Nova kept New York ahead and the Yankees made it another tough visit for Minnesota.
Joba Chamberlain, Rafael Soriano and Mariano Rivera each pitched a scoreless inning to close the Yankees' 14th victory in their last 15 home tries against Minnesota - that includes wins in New York's opening-round playoff sweeps over the Twins the last two years.
Rodriguez lined his 615th homer in the first, then Posada connected the next inning for his third home run in two days. The shots off Scott Baker (0-1) gave the Yankees 11 home runs through their first four games.
Nova (1-0) tossed six effective innings in his season debut.
Jim Thome had a two-run double for the Twins.
Rangers 6, Mariners 4
ARLINGTON, Texas (AP) - Nelson Cruz became the third player in major league history to homer in the first four games of a season and Texas beat Seattle to remain one of four unbeaten teams in the big leagues.
Texas (4-0) is off to its best start since opening 7-0 in 1996, following up a three-game weekend sweep of Boston. Cruz joined Willie Mays (1971) and Mark McGwire (1998) as the only players to go deep in each of their first four games of a season.
Derek Holland (1-0) allowed three runs and seven hits with five strikeouts in six innings. Neftali Feliz worked a perfect ninth for his first save.
Elvis Andrus got the Rangers rolling in the first inning with his first homer in 705 at-bats. Julio Borbon had a two-run triple.
Seattle lefty Erik Bedard (0-1) allowed five runs - three earned - and four hits over five innings in his first start in 20 months.
