Every so often, a characterization of a player made by a handful of fans or media members takes on a life of its own, spreading with reckless abandon until most fans believe that unsupported conclusions are incontrovertibly true. That is how you end up with people claiming that Jesus Montero has a bad attitude, or believing that nobody but the ballboy wants to throw to Jorge Posada. Two of my least favorite chestnuts involve Joba Chamberlain’s work ethic and A-Rod’s general impact in the clubhouse. Joba has constantly been assailed from all corners for being lazy and entitled, as people often throw the “too much success too soon” line in his direction. Regarding Alex, the old line about him was that having him in the clubhouse created a 24+1 attitude, and that he only looked out for himself.

Today, a handful of stories dispelled these myths. On Joba, we have Joel Sherman:

What is not possible, at least for now, is sending Chamberlain to the minors for two major reasons: 1) The Yanks feel it would be a terrible message to bust somebody from main set-up man all the way to Scranton in one move, so they will try to fix him outside the eighth inning and 2) They do not believe Chamberlain is failing because of an attitude problem. Yankee officials actually consider Chamberlain a hard worker. In other words they are not looking at this how they viewed a situation with Melky Cabrera in 2008. That season the Yanks thought Cabrera had become lazy and that was a factor in his struggles, so they did demote him in mid-August to Triple-A.

Will all the claims that Joba is just a fat entitled kid coasting on his success in 2007 disappear? Of course not. But they should, because the Yankees know a lot more about Joba’s work ethic than you and I do. My advice: the next time you find yourself reaching for the “entitled” and “lazy” and “ten cent head” bullcrap, just stop.

In regards to A-Rod, Ben Reiter at SI had some fantastic quotes:

“I can only speak for the last two years, but he’s been a great teammate,” says CC Sabathia, who spent one of his first days as a Yankee two years ago standing off to the side in one of his trademark many-XL t-shirts, watching his new teammate conduct his PED-use-admitting press conference, and probably wondering what he’d gotten himself into. “I know he cares a lot about the younger guys, teaching them and talking to them. Him and [Robinson] Cano are really close — he’s always talking to him. He tells guys what they need to be told, but he doesn’t put himself out there and draw attention to it.”

Last October, when I asked catcher Francisco Cervelli which of his teammates had most helped him transition from a .233-hitting minor leaguer to a rookie big leaguer who batted .298 and seamlessly filled in for an injured Jorge Posada, his answer was as quick as it was surprising. “A-Rod,” he said. “He helps me with everything — everything. I learn so many things from him, calling the game, offensively, defensively, game situations, everything. He’s the man. Maybe he saw at the beginning that I want to work, I want to play, and he wanted to help me. I feel lucky to have him.”

Chad Jennings added the following:

Several weeks ago, Andy Pettitte was talking about Alex Rodriguez and said this: “He can tell me almost every pitch I’ve thrown throughout the course of a game… He’s always in the game. His head’s up. He’s always prepared. That’s why he’s such a great player.”

Last night, Rodriguez said this: “I chased in the first inning, a slider down, but Westbrook had good stuff. He had us off balance all day. With the exception of a 3-2 fastball away to Jorge, and I think it was a 1-0 changeup to Granderson, he didn’t make many mistakes.”

Alex is far from perfect, and I am sure that there are times that he is a distraction. But on balance, he seems to be a very good teammate and, from the quotes in the Reiter piece, it is clear that he has become a leader and example for younger players. So what do we have in A-Rod? A leader who is always prepared and has his head in the game. Next time someone rips on Alex for being a constant distraction and a clubhouse issue, point out these quotes. The public perception of Alex as entirely selfish and self-centered is just plain wrong.

Since we have gotten into the habit of dispelling a number of myths over the last few days, I thought we might look at one more: Lineup protection. Ever since Alex Rodriguez has returned, people have been crediting him for Mark Teixeira’s resurgence. However, most statistical studies have found that the idea of lineup protection produces at best a negligible effect. In fact, JC Bardbury has done a study that shows having a great hitter behind you may actually hurt the batter’s chances of reaching base:

The play-by-play data allowed us to control for the game situation during every plate appearance. While we were looking at protection, we were also curious in identifying another possible spillover, which we call the effort externality. While having a good hitter batting behind you might put more balls in the strike-zone, it doesn’t mean these pitches are of the same quality than with a poor hitter on-deck. It’s not that the pitcher just wants to avoid walking a batter when a good hitter follows. The pitcher wants to keep the hitter off-base any way he can. Pitchers are not dumb. They understand that putting more balls in the strike-zone increases the chance that the hitter will reach base via a hit, possibly with power. So, pitchers may reach back for a little extra gas in these situations. This means that a good on-deck hitter has reason to lower a current batter’s chances of reaching base via a walk AND a hit. If the effort effect is larger than the protection effect, then a good on-deck hitter can hurt rather than help the batter in front of him. Since the effect is ambiguous we need to go to the data.

The results lead us to not only reject the protection hypothesis, but also we find evidence that good on-deck hitters actually harm the hit and power probabilities of the current batter. This is consistent with the effort hypothesis. However, the magnitude of the spillover is tiny and for all practical purposes the effect is zero. Even very good (bad) hitters have only a very small impact on the batters who precede them.

Basically the study shows that being protected in the lineup has zero effect on the performance of the hitter. Mark Teixeira is killing the ball now because he is a very good hitter who typically heats up over the course of a season. When he slumps later in the season, those citing lineup protection now will conveniently discard the argument until he heats up again. For the rest of us, we know that this is part of the typical ebb and flow of baseball, a game of streaks.

This issue has come up on a number of occasions on this blog, and was brought up in the comments of the last post. I want to put the idea that Jorge Posada does not call a good game to bed. People have this idea that because strong willed guys like Randy Johnson, El Duque, and Mike Mussina threw to the backup catcher rather than the equally stubborn Posada, Jorge must not have called a good game. Here are some objective numbers that use CERA (catcher’s ERA, the team’s ERA when he is catching) to dispel this notion. The stats are courtesy of a commenter on Lohud named no. 27:

2007: +.01
Team ERA- 4.49
Posada CERA- 4.50
2006: -.04
Team ERA- 4.41
Posada CERA- 4.37
2005: +.15
Team ERA- 4.52

Posada CERA- 4.65
2003: +.11
Team ERA- 4.02
Posada CERA- 4.13

2002: -.07
Team ERA- 3.87
Posada CERA- 3.80
The only years Posada’s CERA was significantly above the team ERA was in 2003 and 2005. In 2005, Randy Johnson was the Yankees best pitcher and Posada didn’t catch him. If you take out Johnson’s stats, the team ERA is 4.65 compared to Posada’s 4.67 CERA. Not significant.
In 2003, Posada’s CERA was .11 higher than the team ERA. I’m not sure why that would be. At the same time, you could look at Jason Varitek’s CERA for 2005. He’s supposed to be one of the best game callers in baseball and his CERA that year was 5.03, much higher than the team ERA of 4.74.

Basically, Yankee pitchers over the relevant time frame pitched just as well with Jorge behind the plate as they did with anybody else. Posada has never been a great defensive catcher, but his game calling skills are, and always have been, just fine.
