Hey Chop, just punched some numbers on the Mariners as mentioned earlier.
First, Nelson Cruz is due for some bad games. He simply can't sustain his pace. He's not hitting .350 and 55 homers or whatever he's on track for. Not in today's game.
Beyond that though the Mariners look poised to score some runs. Cruz carried them early in the year when the rest of the team was cold. There isn't another player on the team (other than Seth Smith by the tiniest of margins) hitting beyond my projections when it comes to batting average. That means to me that the hits will start to increase before too long. That being said, the team only has 2 great hitters, maybe 3 with Seager. Cano should get going any day now. He can't be as shot as he's looked.
Seattle has a team with some decent power hitters. Cruz and Smith aren't going to keep up their pace and there really isn't a ton of HR upside potential beyond Cano on this team (on track for 2.6, I have him around 10-14 HRs). Everyone doing about what they should do. Seager coming into his own. LoMo finally realizing potential. Zunino has 25 HR potential. Rickie Weeks could come close to 20. Same for Ackley. I like Brad Miller quite a bit and think he'll start hitting soon.
Ultimately when Cruz regresses it will be up to the rest of the team to take over. If Cano hits as I think he will they should be okay. Guys like Zunino, Smith, Ackley, Jackson, Weeks, Taylor, and Ruggiano all have room to bring their batting averages up. The power should be okay. Consistent but nothing special.
I don't see scoring going up or down much from what they've done thus far. When Cruz starts having bad games he'll offset the extra runners on base a bit. The bottom half of the Seattle lineup is who I think will carry the offensive load when that happens. Maybe I'd put the Mariners' offense up a tick because they are so heavy in batting average regression forcing the hits to come, but Cruz trending down offsets it a bit.
Didn't look at pitching yet.
