Bruce Rondon, a rookie trying to become the Tigers' closer, stood on the mound at Joker Marchant Stadium on Saturday in his first spring training game.

Rondon already had walked one and hit the umpire on the leg with another pitch when Toronto catcher Josh Thole stepped into the batter's box.

"Man, it looks like he's throwing hard," Thole said.

"I have no idea where it's going right now, either," catcher Alex Avila said to Thole.

He wasn't joking.

Rondon started wild but settled down and didn't allow a run in one inning.

Rondon threw 12 pitches. He gave up a double and walked one, putting runners on second and third -- a great test for the young flamethrower -- but he proved he can get out of trouble. He settled down, found the strike zone and ended the inning with two strikeouts.
