Here are some surprising pitchers from April. I didn't focus on Wins, ERA or WHIP because I find all three of those stats to be a little bit too luck-driven over the course of just five/six starts. And frankly, there are just too many "surprises" to make the list shorter and more interesting. Instead, I used a couple of less obvious stats - k/9 and GB/FB ratios.
| Pitcher | K/9 | Pitcher | GB/FB |
|---|---|---|---|
| Chad Billingsley | 13.01 | Edinson Volquez | 2.5 |
| Jonathan Sanchez | 10.69 | Brett Tomko | 2.45 |
| Todd Wellemeyer | 8.76 | Odalis Perez | 2.18 |
| Johnny Cueto | 8.49 | John Lannan | 1.96 |
| Edinson Volquez | 10.13 | Zach Duke | 1.93 |
| Micah Owings | 8.13 | Braden Looper | 1.73 |
| Clay Buchholz | 8.47 | Ubaldo Jimenez | 1.74 |
| Scott Baker | 8.1 | Jair Jurrjens | 1.72 |
| Chien-Ming Wang | 6.23 | Nick Blackburn | 1.61 |
