Jekyll or Hyde?

[Matthias]

Which Jonathan O. Sanchez is the real one?

9IP, 10ER, 13HA, 4BB, 11K's (starts 1 and 3 on the season)
11IP, 0ER, 5HA, 6BB, 15K's (starts 2 and 4 on the season)

[J35J]

Which Jonathan O. Sanchez is the real one?

9IP, 10ER, 13HA, 4BB, 11K's (starts 1 and 3 on the season)
11IP, 0ER, 5HA, 6BB, 15K's (starts 2 and 4 on the season)

Somewhere inbetween but regardless will likely sport a 4.5 BB/9 most of the year.

[AussieDodger]

Who knows?
The only time he has accumulated a large string of starts in one hit was at A level.
If you can afford to have him in your staff this year enjoy the ride.
At best he might be like old-school Randy Johnson, 200 Ks at 10 K/9 with 100+ walks.

[Yoda]

Start him every other game.

Does he remind anyone else of Ollie Perez or is it just me?

This one

20 IP, 10 ER, 18 H, 10 BB, 26 K (starts 1-4)

He needs to learn how to pitch when his command is off to become a good pitcher. That can take guys a while sometimes and it isn't something he ever fully figured out in the minors.
