Current Brewers prospect Mike Jones was called up first during the 2006 season, where he pitched only one inning. He was called up again in 2007 and started two games before a season-ending injury. In 2008, he made 6 major league starts, going 1-2 with a 7.75 ERA before being sent back down to AAA.
In early 2009, he was called up one more time to replace one of my injured starters in the rotation. He didn't give up a run until his 4th start, and finished the season 14-3 with a 2.03 ERA, and was a big part of our World Series win, going 3-0 with a 1.14 ERA in the playoffs.
edit: seems that I have another awesome quasi-rookie pitcher in 2011. His last four starts look like:

I brought this guy up a couple times over the past two seasons, but he didn't play all that well. He had a few rough starts earlier this season, but seems to have hit a hot streak.
