I like to do a rough estimate of a team's strength by starting off with their 2011 totals for runs scored and runs allowed, adding and subtracting for new players and projected performance, and see where we end up. Here is an estimate I a did a couple weeks ago on the Washington Nationals. With the Miami Marlins playing the Red Sox on ESPN this afternoon, and Tristan Cockcroft asking how Hanley Ramirez will bounce back , I thought I'd tackle the Marlins.

For all the hype around the Marlins, they won just 72 games a season ago. They scored 625 runs and allowed 702, which creates an estimated win-loss record of ... 72-90. Obviously, the Marlins move into a new park this year. Some believe it will be a better hitter's park than the old place. We haven't factored this into the numbers below.

**Catcher: John Buck, Brett Hayes**

Buck carried one of the heaviest workloads of any catcher in 2011, starting 129 games. I'd suggest the heat and humidity of the Florida summer caught up to him, but he hit just as poorly in the first half as the second half, and his .687 OPS was a fry cry from the .802 OPS he posted with the Blue Jays in 2010, when he made the AL All-Star team. Of course, 2010 was his career-year, his OPS+ of 87 essentially matches his career mark of 89. In other words, expect more of 2011, not 2010. **No change.**

**First base: Gaby Sanchez**

Sanchez made the 2011 NL All-Star team, which I think says more about the state of first base in the National League than Sanchez's abilities. He did hit .293 in the first half, but slumped to .225 in the second half, leaving his overall numbers pretty similar to what he posted as a rookie in 2010. While you might normally project growth for a third-year player, Sanchez is already 28; he's not likely to get better. He is what he is. **No change.**

**Second base: Omar Infante**

After hitting .309 from 2008 to 2010 in part-time role with the Braves, Infante was exposed a bit as an everyday player and hit just .276. He played a good second base, and I do believe he can do a little better with the bat as his BABIP was .298, down from .343 over the previous three seasons. Let's give an **extra five runs** here.

**Third base: Hanley Ramirez**

Marlins third basemen weren't a complete disaster in 2011, hitting .260/.315/.347, but with just six home runs and 44 RBIs. Believe it or not, that OPS was 12th in the NL. Anyway, a healthy Ramirez will obviously be a huge upgrade. For all the concern about Ramirez handling the move to third base, the other part of the equation is Ramirez has fallen off the plate the past few seasons, from .342 to .300 to .243. Most of the projection systems have Ramirez creating 90 to 100 runs, about what he produced in 2010 (97), but fewer than 2009 (122). Let's give 100 runs created here. Last season, Marlins third basemen created about 69 runs, so that's a **31-run improvement**.

**Shortstop: Jose Reyes**

While Ramirez struggled at the plate in 2011, Emilio Bonifacio did a nice job filling in when Ramirez was injured. Marlins shortstops created about 87 runs. Reyes created about 105 runs a year ago -- in 126 games. Of course, he hit a career-best .337, which led to career-bests in on-base percentage and slugging percentage as well. The projection systems estimate Reyes around 80 to 85 runs created in a similar amount of playing time -- hitting about .300 with a .350 OBP. Let's give him 85 runs created and a few more for his substitute, giving 105 overall, an **18-run improvement**. Certainly, that's probably conservative. Maybe Reyes stays healthy for 150 games and creates 115 runs.

**Left field: Logan Morrison**

Marlins left fielders (mostly Morrison) created 92 runs in 2011. Morrison is certainly capable of improving upon his .247/.330/.468 line, especially in the on-base department. I'm looking for a **15-run improvement**.

**Center field: Emilio Bonifacio**

Chris Coghlan, Mike Cameron and Bryan Petersen each started at least 35 games in center a season ago. None exactly tore it up, and Marlins center fielders posted a collective .317 OBP with 14 home runs, worth about 76 runs created. Bonifacio, serving as a full-time utility guy, hit .296/.360/.393 and swiped 40 bases. He doesn't have any power, and the .360 OBP might be a little over his head, so the projections systems are a little down on him. All told, some combination of Benifacio, Coghlan and Petersen should do a little better. I'll call for an additional **nine runs**.

**Right field: Giancarlo Stanton**

Stanton hit .262/.356/.537 with 34 home runs as a 21-year-old. He could explode on the league this year (in fact, I like him as a sleeper MVP selection). I'm going **plus-13 runs**, and I believe that's a safe prediction.

Leaving aside pinch-hitting and pitchers' hitting, that adds up to a 91-run improvement. That would take the Marlins up from 625 runs (11th in the NL) to 716 runs (seventh in the NL, based on 2011 figures, but just 19 behind No. 2 Cincinnati and Colorado).

Now to the pitching. In 2011, Marlins starters allowed 486 runs in 944.1 innings or 4.6 per nine. Ace Josh Johnson went down after nine starts, but the Marlins received 29-plus starts from four other pitchers. Let's break down the rotation into five slots:

And here's how the rotation stacks up for 2012, using estimates based on various projection systems:

Old guys: 162 starts, 944.1 IP, 486 runs

New guys: 154 starts, 958 IP, 430 runs

Now, you can argue that's too optimistic, getting 154 starts from five pitchers -- after all, Johnson made 33 starts in 2009, but just 37 over the past two seasons, and Zambrano's durability is also an issue -- but that's what we're going with for now. Obviously, you can do your own adjustments if you don't believe Johnson will make 30 starts. Anyway, add in eight more starts at 40 innings and 25 runs (a low estimate of 5.6 runs per nine) and you end up with 998 innings and 455 runs allowed, a **31-run improvement**.

The Marlins bullpen was pretty effective in 2011, allowing a 3.44 ERA, sixth in the NL. The big addition was bringing in Heath Bell as the closer to replace Juan Oviedo, currently on the restricted list after it was discovered he wasn't Leo Nunez. I view this as a minor upgrade; Bell has been one of the game's best closers the past three seasons, but he's also a flyball pitcher who benefited from the deep dimensions of Petco Park. His strikeout rate also took a serious plunge in 2011 (11.1 per nine to 7.3), so that's another red flag. I like some other Marlins relievers -- Steve Cishek is a sidearming groundball machine who was effective against both sides of the plate; Michael Dunn is a power lefty; Edward Mujica is a control guy who throws strikes, but can give up some home runs. If Oviedo returns, it should be a pretty deep pen. Overall, I'm going to project the Marlins' pen as being the same as 2011, when it pitched 515 innings and allowed 216 runs. Since we project more innings from the starters, we'll take some away from the bullpen, leaving it with 461 innings and 195 runs -- **21 fewer runs**.

So we end up with:

Offense: +91 runs, for new total of 716 runs

Pitching: +52 runs, for new total of 650 runs

We haven't factored in defense, where the major changes will be Reyes replacing Ramirez at shortstop, and Ramirez replacing Greg Dobbs and others at third base. Baseball Info Solutions rated Marlins shortstops at minus-16 runs a year ago; Reyes rated minus-11 and hasn't rated above average on defense since 2007. At third base, the Marlins rated minus-10; we don't know how Ramirez will show at third, but I have to think he has a chance at improving on that. In center, the Marlins could also show a slight improvement, as Coghlan got the most innings out there in 2011 and he's a below-average center fielder. Overall, the Marlins could see slight improvement from their defense. Let's say 15 runs, knocking their runs allowed down to 635 runs.

This gives them an expected winning percentage of .530 -- or 86 wins.

*Note: I screwed up the math in the original piece. 716 runs scored and 635 runs allowed translates to a winning percentage of .555, or 90 wins.*
