Felix Hernandez wasn't the only one with mounting pressure Wednesday afternoon at Safeco Field as he progressed toward baseball immortality.

The fielders behind him were a part of it, too. Any miscue, and perfection would be lost.

"That was the most nervous I've ever been in my life on the baseball field," said first baseman Justin Smoak.

The mindset of left fielder Trayvon Robinson was echoed around the diamond.

"I was going to go through a wall for him," Robinson said. "I'd jump in the stands. I was going to sacrifice some limbs."

But Hernandez was in such complete control, his dominance so overwhelming, that no heroics were necessary to preserve his masterpiece against the Tampa Bay Rays. Hernandez struck out eight of the last 12 batters to end the 23rd perfect game in major-league history in appropriate style.
