Stat of the Day - Groundball percentage for SPs

The percentage of all batted balls -- hits and outs -- that are groundballs. Courtesy of The Hardball Times

1. Joel Pineiro - 58.6
2. Derek Lowe - 58.3
3. Fausto Carmona - 56.8
4. Gil Meche - 56.6
5. Josh Johnson - 55.9
6. Roy Halladay - 55.7
7. Mike Pelfrey - 55.1
8. John Lannan - 54.5
9. Rick Porcello - 53.6
10. Aaron Cook - 53.0
11. Justin Masterson - 52.8
12. Jason Marquis - 51.4

13. Jeff Suppan - 50.9
14. Felix Hernandez - 50.6
15. Ubaldo Jimenez - 50.0
15. Paul Maholm - 50.0
17. John Danks - 49.2
18. Trevor Cahill - 49.0
19. Joe Saunders - 48.7
20. Nick Blackburn - 48.0

- It had become obvious that Pineiro was getting more grounders than usual, but I'm still quite surprised to see him topping this list. Not only is he getting tons of grounders, but he's walked just seven in 54 1/3 innings. That's resulted in a 3.48 ERA on a team with poor middle-infield defense. His groundball rate had been right around 48 percent the previous three years.

- Pineiro, though, still isn't in Brandon Webb territory. The ailing Diamondbacks ace finished at 64.2 percent last year and is always over 60.

- Pelfrey is up from 48.3 percent in 2007 and 49.6 percent last year. However, he's still sporting a 4.61 ERA because of his 11/17 K/BB ratio in 41 innings.

- We'd expect these groundball pitchers to be among the best in the league at preventing homers, and Meche, Jimenez, Lowe and Pineiro have been. However, Suppan, Porcello, Cahill and Lannan are allowing homers on more than 16 percent of the flyballs they've given up.

- Porcello, at least, may already be taking a step forward. All six homers he gave up came in his first four starts. He's gone three straight without allowing one.

1. Ted Lilly - 25.5

6. Kevin Slowey - 30.9
7. Chris Young - 31.3
8. Adam Eaton - 33.1
