If manager Mike Scioscia needed any ammo to fire up his troops, it was grooved like a Doc Gooden fastball at the belt by stat maven Nate Silver in his PECOTA ratings for Baseball Prospectus.

Silver, it turns out, doesn’t think much of the Halos — specifically, what he sees as an aging offense creating more headaches for Angels pitchers than rival managers. PECOTA has the Angels finishing 16 games off their MLB-best 2008 pace with a mere 84 wins, barely managing to prevail in what it envisions as a weak AL West.

I can understand some anticipated slippage with Mark Teixeira and Garret Anderson departing; those are two high-quality offensive players. But Bobby Abreu has been a fairly consistent 100/100 man (runs. RBIs), and he should fit nicely between Chone Figgins and Vladimir Guerrero in Scioscia’s projected top third. Of course, a big spring by Howie Kendrick, Erick Aybar or Maicer Izturis could convince Scioscia to plant Abreu in the No. 3 hole, with Guerrero fourth and Torii Hunter fifth.

The rest of the lineup is deep and potentially much more explosive than PECOTA imagines. Mike Napoli has the tools to go 30/100 with enough at-bats, joining Guerrero on a surgically-repaired knee, and Hunter, Kendry Morales, Juan Rivera all are capable of exceeding 20 homers with 80 to 100 RBIs. If Hunter bats fourth, behind Vlad, he could surpass his career high of 107 RBIs from 2007.

Call me an incurable optimist, but this shapes up as a pretty fair attack — and it has a nice blend of youth and experience, top to bottom.

It was last year at this time that a lot of snipers were relegating the Angels to second place in the AL West behind Seattle, with its new ace,  Erik Bedard. Scioscia, I’m sure, got some clubhouse mileage out of that. I’m sure PECOTA and its views might surface in one of his pre-game chats with the players before too long.
