Jimmy Rollins has been one of the best defensive shortstops in the game. Currently in his 14th season with the Philadelphia Phillies, the charismatic 34-year-old has won four Gold Gloves. Among shortstops who have played at least 10 seasons, he is second all-time in fielding percentage, behind only Omar Vizquel. Advanced metrics also show him in a favorable light.

Rollins has put up some pretty good offensive numbers, too. He has more than 2,000 hits, nearly 200 home runs and more than 400 stolen bases. But when all is said and done, he will be remembered most for his glove.

Rollins talked about his defensive game when the Phillies visited Fenway Park earlier this week.

Sometimes, when I’m supposed to be working, I read things that don’t have anything to do with baseball. Sometimes I’m able to salvage that lost time by twisting my new information into a vaguely baseball-y angle. So it’s been today, when, this morning, I scanned Erik Klemetti’s Eruptions blog. There’s a good new post up, focusing on the matter of trying to predict earthquakes around the globe. (Hint: don’t do it.) I can’t think of a way to write about baseball-y earthquakes. But within that post, toward the start, is a discussion about patterns, and the perception of them where they sometimes don’t exist. Now this — this could be something to put up on FanGraphs.

Contained within the post is a link to this piece at Scientific American. The author talks about “patternicity,” or, as he puts it, “the tendency to find meaningful patterns in meaningless noise.” This might be a pretty familiar concept to you, and the author advances an evolutionary argument for its existence. There’s a reason, it’s asserted, that we’re so good at finding patterns. There’s a reason we try to find patterns where no patterns exist.

The importance of prospects’ ages is frequently debated. Comparing one’s age to the age of to his competition adds significant context, but age is just a number. Age alone hardly provides enough context to discern its true relevance to an individual’s performance.

In one instance, a player’s age without further evidence is meaningful — when a player is young for his league, it demonstrates his organization’s confidence in his abilities. Each player development department knows its players best. They monitor their players’ development daily on and off the field. Over time, an organization builds the largest observation sample of its own talent and it is in the best position to evaluate its players. To be clear, a player’s age relative to his league does not make him a prospect. His abilities do. When a prospects is placed in an advanced league it is a confirmation of his abilities by his organization. Read the rest of this entry »

As I write this, the Pittsburgh Pirates are tied for the second best record in baseball. They also happen to be tied for second place in their own division, because the Cardinals are the only team with a better record while the Reds have matched Pittsburgh’s 33-20 start, making the NL Central the most competitive and most interesting division in the sport right now. The Cardinals are Reds are both excellent teams, and we should expect both to continue to win at a good clip over the rest of the year, but what about the Pirates? Is this another first half mirage that will lead to a second half collapse, or do Pittsburgh fans finally have a contender to root for?

I think the answer to both of those questions is probably yes; the Pirates are playing over their heds and will likely regress over the next four months, but their strong start and their overall talent level should keep them in the race to the very end.

When I realized that the Pawtucket Red Sox were coming into town, I was actually pretty excited. There was a chance to see pitchers Allen Webster and Rubby De La Rosa and position players Jackie Bradley Jr., Jose Iglesias, and Bryce Brentz, and that’s quite a bit of quality on a Triple-A team. By the time the PawSox rolled into town, however, only three of those players were still with the team. De La Rosa had a mild injury to his side the Tuesday before the team came to Louisville, and he would skip his next start. And Jose Iglesias was promoted before the games I intended to watch. Three solid prospects remained. Read the rest of this entry »

You can knock ’em down, but you can’t knock ’em out.

The St. Louis Cardinals’ pitching staff has been decimated by injuries early on in 2013, but the club continues to receive strong performances from rookie pitchers thanks to one of the deepest minor league systems in the game. The next pitching prospect to throw his hat into the ring will be 2012 first round draft pick Michael Wacha, who will face the Kansas City Royals in his big league debut tonight.

Carlos Marmol doesn’t have the highest career walk rate in baseball history. That honor belongs to Mitch Williams, who walked one of every six guys he faced. But Marmol isn’t far behind, and he’s the leader among actives. Marmol has a higher career walk rate than Jason Giambi. He has a higher career walk rate than Brian Giles and Mike Schmidt and Jeff Bagwell. Walks are just part of the package, and Marmol isn’t some kid anymore, so it’s not like they’re about to go away with a mechanical tweak. This is in part due to the fact that Marmol is hard to hit, so he ends up in a lot of deep counts. This is more in part due to the fact that Marmol has had really lousy command.

Control is said to be the ability to throw strikes. Command is said to be the ability to hit spots. We don’t have a measure of command, but we can assume that a guy with Marmol’s walk rate doesn’t list it as a strength on his hypothetical English-language pitcher resume. The walks are part of the reason the Cubs see Marmol as expendable. They’re part of the reason he doesn’t have much of a market, and they’re part of the reason he’s no longer closing. Everybody knows command is a Carlos Marmol weakness. And now we have fun with a quick project.

Three True Outcome Leaders and Laggards So Far
Introduction
Recently in these pages, Cleveland corner infielder Mark Reynolds characterized his hitting approach for the benefit of David Laurila, saying, “I would say my swing is… a controlled train wreck. I just get it down and let it eat.” Will the comment win him a much deserved Pulitzer Prize for Joyous Remarks? It remains to be seen. What it reveals beyond his gift for the language, though, is the means by which he has consistently found himself among the league’s leaders both in strikeouts and home runs.

Below are the current leaders and laggards by all three true outcomes — both by overall percentage and then by averaged z-score (i.e. average standard deviations from the mean in all three categories). Numbers don’t include Wednesday games.
