A look at three top 10-pitching prospects who recently made their PITCHf/x debuts in Arizona.

Spring has sprung. The new baseball year brings fresh hope and excitement to fans everywhere. And, as spring training play begins, it also brings some pitchers to Surprise and Peoria, Arizona, two Cactus League towns with PITCHf/x installations.

The Royals and the Rangers share the facility in Surprise, while the Padres and the Mariners create cross-league harmony in Peoria. This arrangement provides a near-daily flow of data from at least one of the parks. All four host teams and their visiting foes are using plenty of pitchers in these early games. We'll take that as an opportunity to review some new arms.

Russell searches for a fact-based alternative to the Verducci Effect.

A couple of weeks ago, I took on the "Verducci Effect". Tom Verducci of Sports Illustrated has hypothesized that a pitcher who is under 25 years old and who had an increase in his workload of 30 innings or more in the previous season is at greater risk for injury or for a steep decline in performance. This is a great hypothesis, but for the fact that it is not actually true.

The final word on whether the popular theory holds water or is fatally flawed.

Last week, Sports Illustrated writer and Jason Parks man-crush Tom Verducci put out his annual column warning about a specific type of player: A young pitcher (25 or younger) who saw a significant increase in his workload in the previous season over the season before that (defined as an increase of at least 30 innings, including postseason and minor-league work). Verducci claims that this sort of pitcher is in danger of either a significant injury and/or a performance decline in 2013 because his 2012 was much busier than his 2011. It's a proposition that's become known as the Verducci Effect.

A Little Relief

Jonah Birenbaum

Rafael Soriano is off the market, but there are still some potentially useful bullpen arms to be had.

Earlier this week, Jon Heyman tweeted a short list of free agent relievers who could be a reasonable fit for the back end of the Blue Jays’ bullpen. Whether you credit Heyman with clairvoyance or good contacts, it just so happened that one of the names conspicuously absent from that list was Rafael Soriano. Hours later, the 33-year-old right-hander became a member of the Washington Nationals, signing a two-year, $28-million deal with a vesting option for 2015.

In snapping up Soriano, the Nats removed the best available free agent reliever from the market, but they left an assortment of lower-tier options for teams still looking to bolster their bullpens. Ken Rosenthal later listed several teams still interested in picking up a reliever, identifying the Rays, Tigers, Mariners, Marlins, and Mets as potential suitors. Here are some of the options they can consider:

Raising Aces: For Those About to Watch (We Salute You)

5

Doug Thorburn

One pitcher per playoff team who makes a convincing case in favor of watching every pitch of post-season baseball.

This season may have lacked the dramatic flare of 2011’s frantic finish, but the stretch drive of 2012 has been thrilling in its own right, with division races coming down to the final day and one unlikely club making its only ascension to the top of its division at the most opportune time.  After a day of reflection, we are now staring at an unprecedented slate of play-in games to the postseason tournament, where a season's worth of hard work comes down to nine innings of play.

October can be bittersweet for many loyal fans whose teams fell short of the playoffs. Football will lure those whose residual frustration is too great to bear, while others will adopt a more successful team to support through the postseason. But some of our baseball-loving brethren will follow the action regardless of rooting interest, and to those fellow baseball junkies who cherish every last pitch of October baseball: I salute you. To enhance your enjoyment of the next few weeks, here's a list of 10 pitchers who'll be in action this October—one per playoff team—and what makes them worth watching.

Pebble Hunting: How Pitchers React to Home Runs

13

Sam Miller

What do pitchers look like just after allowing one of the longest home runs of the season?

If we learned anything from the Home Run Derby, it's that people enjoy watching home runs go far. We didn't actually learn that from the Home Run Derby. We knew that all along! It is a pretty well-established thing about baseball. I suppose we could just as easily say if we learned anything from the Home Run Derby, it's that large physical bodies such as the earth create an attractive pull whereby things that are flung up in the air will be drawn back down, the distance of flight correlating to the force exerted on the object. If you knew nothing before the Home Run Derby, you learned about gravity, and you learned that people enjoy watching big home runs. This is an introductory paragraph, and it is complete.

There is one small subset of the population we might not expect would enjoy watching big home runs: the pitchers who allow those home runs. We might not expect them to enjoy watching big home runs, but maybe they do. Maybe they have perspective on the thing. Maybe they appreciate the aesthetics of a baseball soaring impossibly deep into the sky. Maybe they're fans, just like you. Maybe not. I honestly don't know.

Are pitchers less effective after taking a break between innings? And if so, should teams do anything about it?

When the third out is recorded, the pitcher goes back to the bench, puts on a jacket (or wraps a towel around his throwing arm), and sits on the bench for the other half of the inning. When his teammates are retired, he slowly trots back to the mound and delivers a handful of warm-up pitches, and he’s ready to go.

In one of my previous columns, I noticed that pitchers throw their fastballs slowest when there is nobody out and the bases are empty—in most of the cases, that’s at the beginning of the inning. One of the questions that came to my mind was whether they are a bit rusty after spending some time doing nothing on the bench.

An expert on biomechanics and a team source talk about their approaches to evaluating and managing pitcher workloads.

For today's article on impervious and not-so-impervious pitchers, I got my David Laurila on, speaking to Glenn Fleisig of the American Sports Medicine Institute—whose name is almost always followed by the phrase, "the world's foremost authority on biomechanics"—and to a scouting executive from a major-league club (affectionately and frequently referred to in the article as "the executive"). Both had a lot to say, and not everything they said fit into the article. One of the things I failed to fit in was their extended perspectives on pitcher workloads and the efficacy of innings limits, so I'm rectifying that by posting both takes here. Dr. Fleisig comes first, followed by the team official.
