I mean Romano, Garcia, Mayza, Merryweather, Richards and Phelps (as a reliver) all have career K/9 over 9. Cimber is the (weak) contact guy. Garcia hasn't exactly shown it yet this year (velo is down a bit from last year so far). We may not have the swing and miss you see in the Yankees pen, but there is a lot of swing and miss in the pen IMO.
That all said - I don't think Garcia is a top notch lockdown guy. I think he's our 3rd or 4th best pen arm (with Cimber) and the gap between him and Phelps/Richards isn't too big.
