Rich Harden is off to a good start:

Harden fired his fastball about 95 mph for most of his 30-pitch session, but his final pitch came in about 98 mph. Johnson, who couldn’t catch up to it, flung the bat away and gave a mock wave to a non-existent crowd.
“You want me to name that one?” he asked Harden. “That’s ‘the Eliminator.’ It’s a super-fastball.”
