The 2013 PECOTA projections are out and I thought I'd post some of the Cubs below. Since you have to be a subscriber in order to download the spreadsheet, I'm only going to include PA and wOBA, which I calculated using the basic formula. For pitchers I'll only show IP and FIP (I calculated this too).
2013 PECOTA Projections for Cubs Batters
PECOTA is projecting the Cubs only score 664 runs so it's not a powerhouse offense or anything. Castro is expected to have the most value at 3.4 WARP and no one else, using the depth charts section of Baseball Prospectus, is projected with more than 1.9 WARP.
2013 PECOTA Projections for Cubs Pitchers
PECOTA loves Kyuji Fujikawa and still really likes Carlos Marmol, but there's still going to be a closer controversy there if both perform as PECOTA expects. As for Jeff Samardzija, I'd not put a whole lot of weight in these forecasts. He beat them all last year because it was clear he had improved. The projections are still weighting the seasons prior to 2012 in which he mostly sucked. PECOTA doesn't think much of Arodys Vizcaino.
PECOTA likes the Cubs pitching. Only the Reds in the NL Central are projected to allow fewer than the 706 runs the Cubs are projected to allow.
Overall, PECOTA is projecting the Cubs to finish in 5th place in the NL Central with 77 wins.
