Shaw had 7 ABs from his last callup, prior to that he had several weeks of crappy production at the MLB level during Hiura's initial undeserved demotion in early June, prior to that Shaw was godawful at the MLB level for 2+ months before hitting the IL with a nagging wrist issue. Shaw's recent AAA production is taken with a grain of salt because he's demonstrated a prolonged lack of production at the MLB level in 2019, and even when he's hitting well he still stinks against LHP. That reduces Shaw's opportunities for consistent MLB at bats on this roster, so if he doesn't mash when he does get a few starts, people are tired of watching him be a black hole in the lineup and he becomes a waste of roster space. Shaw should mash AAA pitching if he's healthy, in fact he should mash MLB RHP if he's healthy regardless of how many at bats he gets - because he is an established MLB player who has proven as much. However, the longer he goes without reminding everyone he can hit well at the MLB level, the smaller his track record of good offensive production looks to both fans and front office folks - Shaw has had a very long leash to get going, if it doesn't turn around with even the limited opportunities he keeps getting when he's put in optimal spots for success it's on him. As for Grisham, he's been putting up video game #'s in AA and AAA for several months now and he's 22 - seeing him excel at his first opportunity in AAA is reason for excitement in his growth as a potential impact offensive player as he develops, while seeing Shaw hit well in AAA is more of a feeling of relief that perhaps he's healthy and can actually contribute at the MLB level.
