There is a discrepancy between the baseball-reference.com game log for Bizzle, which shows 4 innings as you stated, and the milb.com box score that you linked, which shows him pitching just 1 inning, giving way to Landon Leach who pitched 3. Given that Bizzle has gone only for short stints in his prior appearances in the GCL, and he's coming back from the DL, I'm inclined to believe the latter. Maybe there was a temporary transcription error in the game account, and b-r.com just hasn't caught up yet.
