The reason Johnny Estrada caught John Smoltz last night is that he is having trouble swinging left-handed due to his sore back.
He’s been in pain ever since getting blindsided by Darin Erstad on June 6 and has recently received two cortisone shots to relieve the discomfort. It’s too painful for him to swing effectively from the left side right now, so you can expect Brian McCann to get starts against right-handers, and for Estrada and McCann to split time. However, Cox will probably not make the mistake of having Smoltz throw to Estrada again, after getting rocked last night and taking his first loss since, inronically, June 6. The same night Estrada was injured.
