He didn't face any live pitching in either training camp. Players need some time to get up to full speed, hence the reason there is spring training (and now this year summer camp) in the first place. Plus we don't really know how affected he was by COVID. Young and fit people usually don't suffer too badly from it, but some still do. Possible he was set back by that too. CC said he was asymptomatic. Said he was frustrated because he felt great.
