One trait any GM looks for in a starting pitcher is a strong groundball rate. According to FanGraphs, the free agent leaders (100 innings pitched minimum):
- Jake Westbrook – 56.4%
- Jorge de la Rosa – 52.3%
- Jon Garland – 51.9%
- Carl Pavano – 51.2%
- Hiroki Kuroda – 51.1%
An honorable mention goes to free agent Brandon Webb, who had a 64.2% rate in 2008, his last full season. How about a few trade candidates over 50% in 2010? Derek Lowe, Aaron Cook, Paul Maholm, and Edwin Jackson fit the bill.
Ted Lilly is the anti-Westbrook, with a groundball rate of just 29.5%. Bruce Chen, Javier Vazquez, and Aaron Harang also tend to keep the ball in the air.
