We’re only three days from the expansion of major league rosters. On Sept. 1, all players on a team’s 40-man roster will be eligible to play in the big leagues without an accompanying move. Often times, baseball fans are treated to a sneak preview of teams’ top minor league talent as a result of September call-ups; or they’re surprised by a relatively unknown player who manages to contribute over the season’s final month.

In preparation for this year’s roster expansion, I thought it would be interesting to look back at the greatest-ever September call-ups, defined here as players that made their major league debut during the month of September.

There are, of course, two ways to look at this: The first is to look at players — position players and pitchers — who generated the most value for their clubs during their call-up. The second is to look at players whose careers began as a September call-up and then went on to have great careers.

I’m looking at both. Read the rest of this entry »

“Typically what we see is the more you throw that cutter, you can become dependent on it and you start to overuse it and typically what happens to guys that overuse the cutter is their fastball velocity drops. That has been consistent over the years.” — Orioles Director of Pitching Development Rick Peterson

Last week, Orioles Vice President Dan Duquette staked out a stance for his team: “First of all, the cut fastball, we don’t like it as a pitch, okay?” Focusing first on his contention that no frontline pitchers have succeeded with the pitch, and then on his opinion that the pitch didn’t lead to good results, and finally on his assertion about the developmental impact the pitch has on young arms, we found last week that his stance was defensible if unevenly defended.

But hidden within what Duquette said, and what Rick Peterson said afterwards, is an idea that should be testable. Both Duquette and Peterson made reference to the fact that young pitchers that use the cutter too often adversely effect their fastball velocity.

While the Orioles bullpen has continued to keep them in the playoff race, the Orioles rotation has been a bit of a patchwork job all year long, and so today, they’ve reportedly signed a new patch named Randy Wolf.

While you can perhaps make a case for a change-of-scenery helping give players a fresh start, it’s hard to imagine Wolf is going to be anything besides a bad pitcher in the AL East, however. Here are Wolf’s numbers relative to league average from each of the last three seasons.

2010: 105 ERA-/122 FIP-/118 xFIP-
2011: 98 ERA-/113 FIP-/116 xFIP-
2012: 145 ERA-/122 FIP-/113 xFIP-

As is often the case, Wolf’s results have jummped around a bit despite his overall profile not changing much, as his walk rate, strikeout rate, and groundball rate are all pretty close to his career norms this year. However, after a couple of years of outperforming his peripherals due to hits on balls in play and runner stranding, he’s now gone the other way this year, getting victimized by those two variables.

For his career, Wolf has been slightly above average in both hit prevention and runner stranding, so there’s more reason to believe that he has (or had) some ability to outperform his FIP. However, that ability simply moved him from being meh to being okay, and at age 35, he seems to be closer to the meh end of the spectrum. His decline in strikeout rate tells a lot of the story.

The Orioles aren’t exactly flush with pitching depth, and since the Brewers released him, the Orioles are only responsible for the pro-rated league minimum for the remainder of the year. Giving Wolf a roster spot in September in the hopes that he finds some of his previous ball in play voodoo isn’t a terrible gamble for roughly $80,000, but Wolf’s performance trends and the move to the AL East suggest this probably isn’t going to work very well.

It’s basically the cheapest possible solution on the market, but in this case, the Orioles probably will get what they paid for.

Updated: Thanks to the commentors, especially Evan, for double checking my work. I had an issue in Excel that messed up the results for May and June. Charts have been updated.

For most of 2012, the Baltimore Orioles have been playing over their heads. Well, at least when it comes to their expected win-loss record.

Based on the run differential the team has generated, the O’s have amassed 10 more wins than we would expect based on their Pythagorean winning percentage. The team has outplayed its cumulative expected winning percentage throughout the year and — since April — picked up two additional wins at the end of each month. If they sustain this performance and finish August with at least 10 more wins then their Pythagorean winning percentage would predict, they would be just the third team to do so since 2001 (the 2004 Yankees and the 2007 Diamondbacks are the other two).

Some might point to this glaring discrepancy between Baltimore’s actual winning percentage and Pythagorean winning percentage as evidence that the Orioles cannot sustain their winning ways. Of course, this raises the question of whether we really gain anything from a predictive standpoint heading into September if we focus on a team’s expected winning percentage rather than their actual performance.

The answer based on a review of the past decade seems to be no.

“Why don’t you take a look at the chart with the average against cutters in the big leagues, batting average against and then come back and tell me that that’s a great pitch,” Duquette said.

In an interview with Steve Melewski that is destined to provide content for weeks, Dan Duquette outlined the Orioles’ philosophy when it comes to the cut fastball. In essence, the pitch won’t be taught in their minor league organization. “We don’t like it as a pitch,” the Baltimore GM said.

The 2012 MLB season began with a very public bounty of international talent — Japanese stars, Cuban expats and even a Taiwanese surprise. With the season dipping into its final six weeks, we are beginning to see both the good and the bad of these international players who made the direct transition to MLB rookie.

SP Yu Darvish — The biggest star from Japan since Daisuke Matsuzaka has had a very Daisuke Matsuzaka season — much despite steady predictions of the opposite. Well, actually, he has an 86 FIP-minus and 94 xFIP-minus. That’s at least a better FIP than Daisuke’s rookie year, but an identical xFIP.

Dave Cameron has written extensively on Darvish lately, noting Darvish has a command problem, the league has realized Darvish has a command problem, and Darvish has a scary group of command problem comparables.

At the same time, though, Darvish has been adjusting his approach to a less-aggressive (compared to the NPB) league. He has been toying with his repertoire, and I would not be surprised if he entered the 2013 season with a streamlined pitch selection that sets up his elite slider (one of the best in the league) more effectively and simply.

After last night’s victory over the Mariners, the Orioles announced they were calling up top prospect Manny Machado from Double-A and giving him the third base job for the stretch run. Wilson Betemit hasn’t been a total disaster, posting a 100 wRC+ in 356 plate appearances, but he’s one of the worst defensive players in baseball and is dreadful against lefties, so moving him into a 1B/DH platoon isn’t a bad use of his skills.

The promotion is still a bit of a surprise, however, as Machado is a teenager whose numbers in Double-A don’t suggest that he’s ready to start hitting Major League pitching right away. A .266/.352/.438 line isn’t all that different from what Betemit is doing, and of course Machado is posting that line against inferior pitching. But, despite the mediocre looking slash line, there are reasons to think that Machado might be more ready for the big leagues than the raw numbers suggest.

Earlier this week, Sports Illustrated posted the results (in slide-show form, yay!) of recent survey they took asking 228 MLB players to name the most underrated position player in the game. These sorts of things usually generate “interesting” results, and this case was no exception. This is supposed to be a fun exercise, so it would be unfair to complain about the “unscientific” nature of the poll: why 228 players? How were they distributed across the teams? Were they position players themselves or a mix? How many votes did each player get? The notions of “underrated” and is itself vague (underrated by the media? The fans? Statistics?), so the respondents may have been thinking of different things when answering. Wouldn’t a truly underrated player fail to show up on a list of “top underrated players” at all?

Such complaints sort of miss the point. I assume this was simply meant to be a fun way to generate discussion. I personally would have liked to have seen one or two comments from respondents about each player to get a sense of what the respondents were thinking about when they answered. In any case, the list has some results that are pretty hilarious, as one might expect. One way of responding would be to come up with a different list. Grant Brisbee wrote up an excellent list of his own. Another would be to simply go through SI’s list and comment on it.

This post takes the second path, but the truth is, it is not quite the “fisking” one might expect. Yes, some choices are downright hilarious. However, given the qualifications above, I thought the responding players did okay. It is not the list I would have made, but they made some decent choices. Or maybe the list is like the movie Juno: the beginning is so horribly annoying that the rest seems better than it actually is.

The still-surprising Baltimore Orioles are rumored to be “poking around” on Seattle Mariners pitcher Jason Vargas. I am not sure how that sort of physical contact is permissible (nailed it!), but it makes some sense for the Orioles to try and improve their team. Is Vargas the right pitcher to aim for, though, even if they can’t get player like Matt Garza?

Yesterday we talked about the questions facing the National League contenders. Today, we turn our attention to the American League. Every team but the Twins, Royals and Mariners are within four-two-and-a-half games of a spot in the postseason, if you count the wild card play-in game part of the postseason. That leaves us with eleven teams still playing for something in 2012. Or does it?

In the American League East, the Yankees have a comfortable seven-game lead, and seem poised to pull away with the division title. Yes, with injuries to CC Sabathia and Andy Pettitte, the Yankees could improve by adding a dependable starting pitcher, but so far they haven’t been linked with the starters most likely to hit the trade market. Overall, though, the Yankees are in the best shape of any team heading into the second half.
