Suarez went six not seven. Peralta has a problem with bad misses at times w/2 strikes, that more than anything else keeps him from going deeper.
I already said what I think re Frelick in CF, and apparently they agree. Trust me, they aren't going to dick around with the run prevention because of so-called 'automatic outs'. Look at it this way; If you're having trouble scoring runs, do you really want to mess with your best defensive lineup? And how much of an issue has it been, really? They scored 8 in the opener of this series, and then 6. In Toronto they scored 7, 4, and 4. Today Suarez who's been excellent, has the added advantage of a wide zone today (as did Peralta) and the guy shut us down. He's done that to folks before.
Another snippet re the defensive side of the ball: he wasn't out there today, but maybe Frelick catches the ball in RF that went for the triple? I'm not surprised he wasn't in the lineup. Just illustrating something most folks overlook.
At the end of the day, I wouldn't be surprised if Chourio is in CF this weekend.
