He's a veteran, he's more consistent, and he strikes out less than a lot of the guys in the lineup. Our situational hitting is absolutely horrid, and someone with Lowrie's skill set will help tremendously.
He was starting to regress well before that. There's always an adjustment (unless you're super-human phenom like #1 is).
As much as I bash him (and he just isn't that good), I'm okay with him being the punching bag than some player. Ash is just an easy target. And we just got our first intriguing of the day.
Taking away the threat of the infield single (with the injury) takes away a good chunk of his hitting ability.
His ability to still get a hit/make contact without much speed still probably outweighs what Marwin can do. Now, if they want to put him on the DL and call up Kemp...
True, Altuve is still better the Marwin. If Altuve's hamstring continues to nag him, wouldn't mind them putting him on DL and getting a look at Kemp.
