These are amazing numbers that Guo is putting up. His FIP and BABIP go to show that his great numbers are NOT luck based. Comparing his 2008 stats with his career line, Guo's biggest improvement this year is in his control, or lack of walks. Bluntly put, Guo is walking less batters this year than in the past. Combine that with Guo's skill of suppressing homeruns and his amazing strike-out ratio, good things are going to happen. Hopefully, Guo will continue to see some high leverage situations, so the Dodgers can reap the benefit of Guo's tremendous talents. In 5 of his 6 appearances, Guo has pitched in above average leverage situations. Prior to the last 6 appearances, Guo appeared in 6 consecutive very low leverage situations.
