Very recently, Dan Uggla was one of the better players in baseball. Two years ago, his 135 wRC+ put him in the same company as Ryan Braun, Prince Fielder, Adam Dunn, and Joe Mauer. He hit for average, he hit for power, he drew walks, and he faked it at second base well enough to provide a lot of value, averaging +4 WAR per season during his first five years in the big leagues.

Last year, Uggla looked lost for the first three months of the season, as he wasn’t drawing walks and his BABIPs were below .200 in each month from April through June. However, for as bad as his first half was, his second half was equally amazing, as his power spiked, his BABIP returned to normal, and he closed the year looking like the Dan Uggla of old. The overall line was down a bit from his years in Miami, but given how well he closed the season, it didn’t seem like an early decline was in his future.

However, there was some evidence of worrying trends, even while Uggla was killing the ball last summer, and this year, the continuation of those trends has cost him his job as the Braves starting second baseman.

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 »

Through the whole course of baseball history, several thousand players have managed to bat at least 200 times. An enterprising position player might reach that mark in less than two months. Given that minimum, nobody’s been a better hitter, relative to the rest of the league, than Babe Ruth, who had a career wRC+ of 197. All right, not learning a whole lot so far. Given that minimum, nobody’s been a worse hitter than one Don Carman. The long-time Phillie batted 239 times and recorded a dozen hits, racking up a wRC+ of -79. After Carman, there’s Ron Herbel, at -73. And after Herbel, there’s Tommy Hanson, at -70. Keep in mind that these are large negative numbers and wRC+ has a plus sign built right into the name. By this measure, current Atlanta Braves starting pitcher Tommy Hanson has been the third-worst hitter in baseball history.

Thursday night, facing Barry Zito in San Francisco, was another normal game at the plate for Hanson. He batted twice. The first time, he grounded back to the mound with two runners in scoring position. The second time, he struck out swinging at a curveball. There wasn’t a third time, because Hanson also pitched poorly, and while the Braves surely would’ve preferred that Hanson pitch better, at least he spared them a third time watching him hit.

Hanson has now batted 47 times this season. That’s roughly a quarter of his career total. There are no signs that his offense is getting better. To his name this season, Hanson has a -78 wRC+ and one hit. What follows is the story of that one hit.

Andruw Jones was having a brilliant career, that is, until he turned 31 years old. Since that point, he’s barely been a league-average player. He went from an all-time great player, to an iffy hall-of-fame candidate.

Chipper Jones announced in March that he would retire at the season’s end. He cited various reasons for ending his hall-of-fame career and admitted that he was tired of living the baseball lifestyle. Always one to answer questions honestly in an era of generalities, he said that his decision was firm; no matter what, he was done once the Braves’ season ended.

As expected, his steadfastness to that decision has been tested, and reporters frequently ask whether he’s changed his mind. Maybe there’s a point to those questions. After all, Jones has a .379 wOBA and 2.9 WAR right now. And he’s on pace for his best season in four years. He projects to finish the season with a .372 wOBA and 4 WAR, and players don’t generally retire after posting numbers like that.

So where does his final season rank among career-concluding seasons throughout history. Is he truly going out on top?

Last night, on the Sunday Night Baseball telecast of the Atlanta Braves and New York Mets, announcer Dan Shulman facilitated a discussion surrounding relievers and the Cy Young Award.

Quite simply, should Aroldis Chapman and Craig Kimbrel be considered legitimate candidates for the NL Cy Young Award this season?

Relievers possess a difficult time making noise in the Cy Young Award voting because they do not throw nearly as many innings as starting pitchers. Fewer innings equal fewer opportunities to make an impact and provide value to one’s baseball team. This sentiment was largely echoed by Orel Hershiser and Buster Olney on the Sunday Night Baseball broadcast.

The topic of relievers and the Cy Young Award seems to surface annually. This season, however, the conversation has become more earnest because Chapman and Kimbrel are compiling video game numbers on the mound. Just look at how dominant both have been for their respective teams, prior to Sunday’s games:

“As a whole, not specifically regarding potential deals, we need to add a lot of pitching to the system. It’s not enough to have a handful or two. You need waves and waves coming through your system, and we don’t have that. We hardly have even one wave coming, so we need to rebuild a lot of pitching depth.”

–Theo Epstein, July 18, 2012

On Monday night, the Chicago Cubs executed a pair of trades, sending players to both the Braves and the Rangers in exchange for pitching, pitching, pitching. Here’s the breakdown of those trades:

Braves get:
SP Paul Maholm
OF Reed Johnson

Cubs get:
SP Arodys Vizcaino
RP Jaye Champman

***

Rangers get:
C Geovany Soto

Cubs get:
SP Jake Brigham

The Braves trade feels a bit like a fleecing for the Cubs; the Rangers trade is at best a wash. Let us see why.

I’ve written quite a bit this year on trends in pitcher aging, specifically velocity loss and gain. In the last iteration I focused on the odds of pitchers gaining velocity back after a season where their fastball dropped by at least 1 mph.

In that piece I listed a few pitchers to keep your eye on given that their velocity was down from 2011. In June, I wrote about CC Sabathia for ESPN and noted that the big lefty is likely beginning to “age”, as the odds are quite a bit higher that pitchers over the age of 30 do not gain their velocity back once they’ve lost it.

After thinking about it a while it occurred to me that there is of course the chance that these pitchers will gain their velocity back by the end of the year (as I noted in both pieces). We know that, generally speaking, pitchers gain velocity as the season goes on. Temperatures rise, and so too do fastball velocities. If this is the case I wondered at what point in the season we can say with greater certainty that a pitcher is throwing as hard as he is going to throw. Is there a particular month where a velocity decline is more likely to translate to or predict a full season velocity decline?

The starting rotation was supposed to be a strength for the Braves, but they instead opened today with just one qualified starter with a sub-4.40 ERA. Ben Sheets has provided a lift two starts into his comeback and Tim Hudson has been his typically reliable self, but Mike Minor, Randall Delgado, and Jair Jurrjens have struggled to varying degrees while Brandon Beachy blew out his elbow. Atlanta remains right in the thick of the playoff hunt despite ranking middle of the pack in rotation ERA and FIP (both 4.04).

In an effort to shore up the staff, the Braves acquired Ryan Dempster from the Cubs this afternoon. It’s unclear what they gave up as of this writing, though Delgado has been rumored. Dave O’Brien, Jon Heyman, and Mark Bowman all deserve some credit in breaking the news. The veteran right-hander has ten-and-five no-trade protected but waived it to join Atlanta. He reportedly did not demand any kind of extension or other compensation to approve the trade, so he gets brownie points for that.

The Braves are four games back of the Nationals in the loss column in the NL East and four games up on a wild-card spot, so they’re right in the thick of the playoff hunt. They’ve survived some terrible pitching performances and injuries thanks to one of the game’s most productive outfields — a unit that ranks third in baseball with 10.5 WAR. Michael Bourn (4.2 WAR), Martin Prado (3.7 WAR) and Jason Heyward (3.5 WAR) all rank among the 15-most-valuable players — and among the eight most-valuable outfielders — so far this season.

Bourn will be a free agent after this season and Heyward is under team control through 2015, so those two are on the opposite ends of the contract spectrum. Prado, 28, is kind of in the middle. He’ll be arbitration-eligible for the third time next season before becoming a free agent 15 months from now. Atlanta is going to try to prevent that from happening… Read the rest of this entry »
