Here is some more stuff from Kevin Goldstein at Baseball Prospectus:
Unlike Strasburg, There Are No Mitigating Factors
Aroldis Chapman, LHP, Reds (Triple-A Louisville)
Monday's stats: 5 IP, 9 H, 6 R, 1 BB, 8 K
The day after Stephen Strasburg had his worst career start, Chapman followed up with his version. Unlike Strasburg, Chapman wasn't dealing with a tiny strike zone and some cheap hits, he just wasn't on. The fastball was certainly there, as it missed plenty of bats, but his often inconsistent slider was flat all night, forcing him to rely on the fastball and often being forced to groove pitches when behind in the count. He's not nearly as big league ready as Strasburg, and Monday night proved once again that there is still work to be done.
I'm going to the Reds games tonight and tomorrow afternoon so look for some game updates by Thursday at the latest.
