Narveson - right now - is pitching like a LH version of Dave Bush. Same horrible WHIP, similar GB/FB ratios, etc. Bush has the 'benefit' of having given up more unearned runs, which is why his ERA is nearly a run lower than Narveson. About the only thing Narveson has going for him is that he racks up more strikeouts and throws more pitches per start than Bush does. That said, due to his inability to keep his pitch count down (19! pitches / inning), he still can't average 6 innings /start. While Bush's per-start numbers are skewed heavily by the meltdown at Target Field last month, he's still been the more constistent guy, putting up 6 quality starts in 11 chances (compared to 2 QS in 8 GS for Narveson). That isn't the type of performnce I would look to commit to. K/9: Narveson: 8.00, Bush: 4.81BB/9: Narveson: 4.33, Bush: 4.50 K/BB: Narveson: 1.85, Bush: 1.07 xFIP: Narveson: 4.54, Bush: 5.37 If you compare the two pitchers based on WHIP, ER, and QS, then they look pretty similar. If you use statistics that are much better indicators of future performance, it's pretty clear that Narveson projects to be a much better starter than Bush, even if he only projects as a #5 starter.
