This list was a bit harder to narrow down than the hitter list, so I expanded it to 10. However, I think this list is much more open to changes, debate, and modification over the next 6 months.
1. Brett Anderson - He won't show up on a lot of prospect top 10 lists, but that's fine with me. Anderson has been very good, he'll be a #1 starter for a long time.
2. Trevor Cahill - Do A's fans realize that one day they'll have a starting rotation with Gio Gonzalez, Brett Anderson, Sean Gallagher, and Trevor Cahill? It's quite possibly the best young rotation I've ever seen.
3. David Price - My gut instinct tells me to drop Price down closer to #5 or even #6, but I'm going to give him until the end of the year before I pass a final judgment on him. His stuff isn't as good as I originally thought it would be.
4. Madison Bumgarner - Pop Quiz Time! Name 5 pitchers that have averaged a K/9 of 10 or more in A ball at the age of 18. Time's up. Post your answers below.
5. Brett Cecil - I've seen absolutely zero buzz about Cecil, but he's got better numbers than Price, and he's very good.
6. Rick Porcello - I was hoping for higher strike out totals from Porcello, but his ground ball rate has been a nice surprise, and his control is respectable.
7. Neftali Feliz - It makes me sick every time I think that Feliz could have been pitching for the Braves if they hadn't lost him in the Teixeira trade.
8. Jordan Walden - Watch out Nick Adenhart, Walden's catching up really fast.
9. Jeremy Jeffress - Tons of potential, and it looks like he's got his personal life back on track as well.
10. Michael Bowden - Still a few years away from being a solid pitcher in the Red Sox rotation, but he'll be a very nice addition to the Buchholz-Lester-Masterson trio.
Honorable mentions: Jeremy Jeffress, Jose Ortegano, Jarrod Parker, Will Inman, Matt Latos, Nick Barnese
