It’s no secret that there are some differences between the numbers posted on FanGraphs and Baseball-Reference. Even though, in theory, they’re measuring the same things, not everything is black and white, so differences are unavoidable so long as the two sites draw data from different sources. The most well-known case is probably how FanGraphs’ WAR has been different from Baseball-Reference’s WAR. But there are other, less visible cases where the numbers don’t quite match up.

One such case was brought to my attention Monday morning by colleague Carson Cistulli, whose last name I apparently still haven’t added to my Firefox browser dictionary. The idea wasn’t to suggest something had to be written; the idea was to suggest, if something were to be written, it would be written by me. Below, please find the rest of this post.

Barring a late-spring signing of Jose Valverde, the Tigers will be turning to a pitcher new to the closer’s role (or, in the case of Octavio Dotel, many years removed from his last closing opportunity). Things have been rough in the bullpen in spring training, particularly for the assumed front-runner Bruce Rondon, who has allowed five hits (including a home run) and five walks in just four appearances to date.

The competition appears now to be a bit more wide open. Joaquin Benoit, Al Alburquerque, Phil Coke and Octavio Dotel join Rondon as options for the ninth inning in Detroit. Who fits best? To help answer that question, I took a look at what characterized the most successful pitchers to move from a setup role (or other bullpen role) into a closer role the next season.

It sounds like the Yankees have one more name to take off of the list of potential Mark Teixeira replacements. Aubrey Huff is saying he is “pretty much retired.” Although earlier in the off-season he sounded like he still wanted to play, not surprisingly, there was not much interest in a 36-year-old first baseman coming off of a 87 wRC+ in 2011 and a 76 wRC+ in 2012. That should not be how we remember Huff. As Craig Calcaterra noted this mornining, Huff actually had a pretty nice career, and is hardly unique in having to have the game tell him it is time to say goodbye rather than the other way around. There are worse ways to go out than winning two World Series rings in three years. Huff is no Hall of Fame candidate, but his career is interesting for other reasons.

(I guess there is still a chance that Bruce Bochy will get nervous about Brandon Belt and give Huff a call, but we will leave that possibility aside for now.)

Over much of the offseason, a lot was said about the Detroit Tigers heading into 2013 with Bruce Rondon slated to close. Rondon, 22, has a big fastball, and is a quality prospect. But it turns out there’s more to pitching than throwing really hard, and Rondon has limited experience in the upper minors and a demonstrated inability to throw strikes consistently, especially against left-handed hitters. Right now, in Tigers camp, Rondon is being given special instruction, and while there’s plenty of time in spring for him to right the ship, it’s looking less likely by the day that Rondon will close out of the gate. The Tigers want to go to the playoffs, see, and a shaky rookie closer isn’t going to help them if he’s sufficiently shaky.

Rumor has it the Tigers are exploring the current closer market. How important is a closer to the Tigers? On the one hand, closer Jose Valverde had some memorable meltdowns last October, nearly costing the Tigers their season. On the other hand, with Valverde, the Tigers won their division and advanced to the World Series before getting swept away by San Francisco. So Valverde didn’t bring everything down. But the Tigers want security — security in the person of not-Valverde, it turns out — and among the considered options, Rick Porcello makes for a curious one.

They say that, when it comes to understanding anything about the subsequent regular season, you should never pay attention to numbers in March. That’s good advice, and it doesn’t even bother to mention numbers in February. Today is February 25, spring-training competition has only just begun, and nothing matters. To whatever extent any baseball matters, February baseball matters less than April baseball, which matters less than September baseball, which matters less than October baseball. Today’s baseball is only one step ahead of intrasquad action, and there’s not much of anything to be read into.

But even meaningless baseball can generate baseball highlights. It’s been a long time since we were given fresh, new baseball highlights, and earlier Monday, Miguel Cabrera did a mean thing to a Jonathan Papelbon delivery. It doesn’t matter that the game was meaningless; Papelbon wasn’t trying to give up a home run, he threw a normal pitch, and Cabrera blasted it out. Within pointless baseball, there are glimpses of regular baseball, and here is some video for you.

First, Tigers’ general manager Dave Dombrowski said young fireballing right-hander Bruce Rondon would be given “every shot” at closing this coming year. Then there were rumors that the Tigers were “targeting relievers capable of closing.” Last week, the manager said he doubted that anyone would be “anointed the closer out of spring training.” Whether or not there’s a real difference in the team stance at any of these points, there do seem to be some different ideas being put forth about the team’s perception of the closer’s role.

This is, as you may have surmised from the title, the third in a series on trades that players have vetoed, as is sometimes their right. You can find the first two parts here and here.

Every year, around this time, players advertise themselves as being in the best shape of their lives, either because their offseason conditioning regimens improved, or because previously they were lazy. I think the players are almost always being sincere — they probably, genuinely, feel great — but as fans, we identify this as a cliche, and we generally dismiss it. For one thing, we hear this claim entirely too often. For another, it’s never been demonstrated that there’s a relationship between best shape and on-field success. Or, if you prefer, on-field improvement. It’s been studied, albeit not exhaustively so.

There’s something particular I want to examine, though, and it has to do with Jhonny Peralta. This is an article about Peralta from Friday morning. Within:

Fewer pounds would be preferable, they told him, as he headed home for the winter. He got the message and lost 18.

“It’s good,” Peralta said. “I’ve never been at this weight since I’ve been with Detroit. I finished last season at 236. I’m at 218 now.”

Dan Szymborski’s ZiPS projections, which have typically appeared in the pages of Baseball Think Factory, are being released at FanGraphs this year. Below are the projections for the Detroit Tigers. Szymborski can be found on Twitter at @DSzymborski.

Other 2013 Projections: Angels / Astros / Athletics / Blue Jays / Brewers / Cubs / Diamondbacks / Giants / Mets / Nationals / Phillies / Pirates / Rangers / Reds / Rockies / Royals / White Sox.

Batters
On the one hand, we know that the league-average BABIP generally settles within the .290-.300 range. On the other, we also know that Tigers center fielder Austin Jackson has posted a .370 BABIP over his first three seasons (ca. 2000 plate appearances). On the third hand — this being one of those rare instances in which a third hand is present — we know that true-talent BABIP tends not to exceed about .350.

How does ZiPS handle a situation like this? Szymborski addressed a question along these very same lines on Wednesday, writing: “Short version: even at 1960 PA, you expect a player’s BABIP to regress ~43% toward mean.”

Otherwise, here’s a point of interest: Andy Dirks is likely as productive a major-league corner outfielder as Torii Hunter, whom Detroit signed to a two-year, $26 million contract this offseason — and is likely a full win better than the departed Delmon Young.

Note: I found some errors in the data. Data below has been corrected, as well as some conclusions — BP

Yesterday, Jeff Zimmerman examined how Tim Lincecum’s performance has depended to some extent on his ability to pitch to the edges of the plate. Last year, Lincecum was one of the worst starters in the game in terms of the percentage of his pitches thrown to the black. Coincidently (or not so coincidently), Lincecum suffered through his worst season as a professional.

As with many things, Jeff and I happened to be investigating this issue of the edge simultaneously. Of course, we were not the first to dabble in this area. Back in 2009, Dave Allen noted that differences in pitch location–specifically horizontal location–led to differences in BABIP.

Like Dave, I was curious about the overall impact that throwing to the edges–or the black–has on overall performance. My thinking about pitchers throwing to the edges naturally led to some hypotheses:

1. Throwing a higher percentage of pitches on the edges leads to lower FIP.
2. Throwing a higher percentage of pitches on the edges leads to lower ERA.
3. Throwing a higher percentage of pitches on the edges leads to lower BABIP.
4. Throwing a higher percentage of pitches on the edges is associated with lower four-seam fastball velocity.

I think the first three hypotheses are intuitive, but the last one stems from the idea that as a pitcher ages and loses zip on their fastball they cannot remain successful unless they increase their avoidance of the heart of the strike zone.
