CHICAGO -- To hear the word "incomparable" thrown around Ken Griffey Jr.'s name in the past would likely involve the description of his supreme athletic talents.

But now, here stands Griffey at 35 years old, attempting to be an everyday center fielder despite having three screws holding his right hamstring together, and the word "incomparable" takes on new meaning.

"There's no one you can compare me to," Griffey said. "I'm coming back from a hamstring surgery, so every day I'm working with the trainers and trying to make the best of everything. For the most part, I'm feeling better and better each day. And it's just a matter of being patient."

But patience doesn't come easy for a player of Griffey's stature. When he's struggling at the plate, as he has been from the outset of this season, every whiff, groundout or flyout takes on "How the mighty have fallen" stature in the press and in the mouths of fans.

It's April, though. And Griffey is no stranger to slow starts. Just last season, he notched only three home runs and 13 RBIs in April, only to explode with 10 homers and 29 RBIs in May.

Still, Griffey's struggles out of the gate this year are hard to ignore. He came into Tuesday's game with his longest season-opening stretch of at-bats without a home run (64) of his career, and he had knocked in just three runs while hitting .234.

"I think it's just a matter of a few adjustments," hitting coach Chris Chambliss said. "He'll be fine. Everybody has a rough April. But the good news about Griff is he's out there every day, and he's healthy and running around in the outfield and he's getting regular at-bats. With the caliber of player he is and the kind of hitter he is, sooner or later we're going to start seeing some results."

Some results came Monday night against the Cubs, when Griffey went 3-for-5, ending a stretch in which he had just one hit in his previous 21 at-bats. He also knocked in three runs on a double in Tuesday's contest at Wrigley.

Griffey just tries to make the best of each day.

"I'm just trying to be patient," he said. "I have good days and bad days. I'm just trying to do the little things."

The hope is that the big things -- home runs -- will also come with time.

"The man's been hitting home runs all his life, and I don't see how that would change," Chambliss said. "The main thing to me is he's hitting the ball hard consistently. The power will take care of itself eventually."
