When playoffs comes around they have a 1-4 that can go deep and Porcello can move into bullpen to help in that regard
A's have a good staff but that lineup just isn't that good
It's better than the Tigers' lineup.
Kinsler, Cabrera, Martinez, and whatever JD Martinez turns out to do through the season.
The A's traded, honestly, one of their middling hitters. Cespedes is a good player, but nothing that's exceptional. Moss, the Norris/Vogt platoon, Jaso and Donaldson are more important to that lineup.
And it's not necessarily true that the A's are done. They could still make some moves in August.
