This is the still the weird thing about Suarez - it would be silly to have him be the default 9th-inning guy when he can give you two innings (or more) against tough spots in any line-up at any time. But when he's the best option, he's the best option, whether it's 3, 4, 6 or 7 outs.
We'll see how things shake out after the break, they still gotta get some of these other guys right.
Same thing with the trades, it's been a great July starting with the Padres series, and a great road trip but they still have another 6-10 games to get through before the market really heats up. I'd still want to see them take 3 of 4 from Miami and at least split in the Bronx, but obviously so long as the division remains in striking distance they will do something.
