My first reaction to this was: "I like that less than Keller for 2/22", but on second look maybe that's not the right way to think about it? Weaver has much better K/BB over the last two seasons, including, importantly, more Ks period. One of them saw the performance back up, the other broke out. Keller is a GB machine, Weaver is an extreme flyball guy with not as many pop outs as you would think from such a pitcher. Track record of success is equally limited for the two of them, although Weaver was generally more promising during his starting days than Keller was, and has one more season of good performance. Keller has the age advantage and the velo trending up.
