How easy on the eyes was the Yankees' home opener yesterday?

Take it from a man who has seen so many yesterdays — it was something.

"That was the finest I have ever seen,'' former trainer Gene Monahan said in the clubhouse following a pristine 5-0 win over the Angels in front of a sun-splashed and sold-out crowd of 49,386 at Yankee Stadium.

Considering yesterday was the 40th home opener Monahan witnessed, his words aren't empty.

On a perfect April afternoon, punctuated by Jorge Posada's pre-game appearance, the Yankees delivered a performance that hiked the winning streak to four and will be difficult to top across the remaining days of the schedule.

"You get an early lead and your starter gets into the ninth, I don't think it gets any better,'' manager Joe Girardi said.

The Yankees — or any other team — will be hard-pressed to play a better game. Nick Swisher's three-run triple off Ervin Santana in the first inning staked Hiroki Kuroda to a 3-0 lead. Alex Rodriguez slugged his first home run of the season and 630th of his career in the third. Curtis Granderson's second homer in as many games was hit in the fifth.

Punished by Tampa Bay last week in his Yankees debut for six runs (four earned) and eight hits in 5 2/3 innings, Kuroda was asked to rebound on a big stage and against a better lineup than the Rays have.

Kuroda (1-1) responded with eight shutout innings in which he allowed five hits, walked two and fanned six.

"He went out there and wanted to prove what kind of pitcher he is,'' pitching coach Larry Rothschild said.
