Well, let's go position-by-position:
- First Base: Rizzo is a year older and should be better. 2013 > 2012.
- Second Base: Barney is Barney. Push.
- Shortstop: Castro is a year older and should be better. 2013 > 2012.
- Third base: Still likely to be awful. Valbuena was the best performer of the group last year, so you could see a little improvement just by not giving ABs to Mather or Vitters. Still, this is a push.
- Outfield #1: Soriano is a year older and should be declining. 2013 < 2012.
- Outfield #2: DeJesus is a year older and should be declining. 2013 < 2012.
- Outfield #3: Schierholtz and Hairston aren't exciting, but are competent...possibly good enough to be roughly league average in RF. They're taking the ABs given to mainly awful players last year: Mather, Byrd, LaHair after the league had figured him out, Baker, and Campana, with a few league average-ish PAs turned in by Reed Johnson. This is a massive upgrade, 2013 >>> 2012.
- Catcher: Castillo can reasonably be expected to be a .250/.320/.400 hitter this year, and has a little bit of upside. With a little luck, he'll be around a league average starter. Navarro is a perfectly capable backup, who should ensure that the Cubs at least get anti-awful performance out of the position if Castillo bombs. Soto/Clevenger/Hill/Lalli/Recker provided nothing resembling anti-awful performance. Another big upgrade, 2013 >> 2012.
So two positions that should be major upgrades (just because the names aren't exciting doesn't mean the upgrades aren't huge), and two that are a push. The improvements from Rizzo and Castro should cancel out the declines of Soriano and DeJesus, although there is a significant chance that one or both of the young players could really break out as true stars. The lineup is better. Not good by any stretch of the imagination...but good enough to move up to 11th or 12th in the league instead of dead last.
Thanks for BR's position by position comp.
Let's look at the data. Cubs were awful offensively at four positions last season: 3B, C, CF, and RF.
1. 3B we've already covered the last few days. .611 OPS and -154 OPS compared to NL average. Even with the same guys, this will be better because of random luck, if nothing else. This is a virtual lock to be better. How much, who knows.
2. Catcher- Cubs catcher OPS was .616. That was #15 in NL and -106 OPS compared to NL average at the position. The more that Castillo plays, the more the Cubs will improve compared to last season. Hard not to upgrade from .616 OPS from 2012.
3. CF- Cubs CF OPS was .640. That was #14 in NL and -100 OPS compared to NL average at the position. Keep in mind how this happened. Campana started 33 games in CF with a .628 OPS while playing CF. B. Jackson started 38 games with a .670 OPS in CF. Joe Mather started 26 games in CF with a .572 OPS as a CFer. Marlon Byrd started 13 games in CF with a .483 OPS as a CFer. Gotta think this will be considerably better than .640 in 2013.
4. RF- Cubs OPS was .688. That was #15 in NL and -80 OPS compared to NL average in RF. DeJesus only started 86 games in RF and did well, but LaHair started 32 games and was .633 OPS as a RFer, Jeff Baker started 11 games in RF with a .438 OPS as a RFer, and Mather went 1 for 20 in RF. Again, Cubs figure to improve from .688.
In sum, Cubs were either #14, 15, or 16 at four positions in 2012--basically 1/2 of the lineup. I know that this sounds lame, but even going from awful to poor at FOUR positions in a real upgrade. That's a lot more runs scored. Maybe there even will be an average or two in that group.
Other positions in 2012 in OPS compared to NL average: 1B was + 19, 2B was -29, SS was +54. and LF was +21.
Hard to see that Cubs will be worse at three of the four positions that were good/okay, with the possible exception of LF. Obviously, the key there is whether Soriano will fall off considerably or be traded, perhaps resulting in a downgrade in LF. Still, it's not like Cubs had a monster offensive year there at .783 OPS. It's not like losing Sammy in a prime year to the next.
So, overall, hard to argue that Cubs won't score more runs in 2013, seems to me. I expect the offense to be below average but better than awful.
