The SF Giants got some bad news recently with left-handed reliever Erik Miller going on the IL and being diagnosed with a UCL sprain. Thankfully, Joey Lucchesi has stepped up and looks to be an obvious internal replacement.
The optimistic view on Miller is that he could be back in roughly a month which is a positive, but we know elbow injuries to pitchers can be tricky. It is a shame because Miller was having an excellent year and was establishing himself as a key part of San Francisco's bullpen.
