One of the metrics for evaluating situational hitting is RE24. For those of who aren’t familiar, that stands for Run Expectancy in the 24 base-out states.

RE24 is calculated as the difference in run expectancy before and after a PA, plus any runs that score as a result of the PA. The run expectancies in that calculation are based on empirical results for each base-out state, from nobody on, nobody out to bases loaded, two out. Run expectancy means how many future runs would expect to score in an inning starting from each base-out state, assuming a team of identical average hitters facing identical average pitchers. The run expectancies are pretty intuitive: the more runners on and the fewer the outs, the higher the run expectancy, and vice-versa.

RE24 for a PA can be positive or negative and thus can be summed over a game, a season, or a career. The results apply to both pitchers and hitters. Thus, a positive RE24 for a batter in a given PA is a negative RE24 for the pitcher, and vice-versa. One caveat is that RE24 scores are not adjusted for inning, game score, batting order position, platoon advantage, park effects, or anything else. Thus, RE24 is often most useful when comparing players on the same team.

Derek Jeter has long had the nickname Captain Clutch, a moniker usually attributed to his post-season performance. Indeed, that post-season career reads pretty much like a a full season stat line. A very good stat line.

But, for regular season play, who are the top clutch performers in today’s game? I’ll tell you after the jump.

These are the only players since 1901 with a particular seasonal batting feat, first introduced by Jim Wynn. A batter before his time, Wynn had been out of baseball for a decade before any of these other hitters had played a full season.

What is the seasonal batting feat Wynn pioneered that is now coming into vogue?

Congratulations to Richard Chester! He correctly identified that these are the only players since 1901 having a qualifying season with more strikeouts than hits, and with a run total exceeding 80% of the hit total. This combination of modest hits and immodest strikeouts surprisingly resulting in lots of runs is, aside from Jim Wynn, a very recent phenomenon.

Which players had the best games of the 2013 season batting from a certain lineup spot? That idle thought crossed my mind, so I thought I’d find out, and then see what kind of a team I could put together with just those players.

Tiger shortstop Jose Iglesias was the AL RoY runner-up, turning in a .300 hitting campaign to go with solid defense (0.989 fielding). That by itself would be an unusual rookie campaign for a shortstop, but a mid-season trade from the Red Sox to Detroit made Iglesias’ season more unusual still.

I was curious how often a rookie who had established himself as the “regular” shortstop (i.e. not necessarily an “everyday” player, but the player used at his position more frequently than any other) had been traded to another team to became its regular shortstop. I figured it was probably unusual, but I wouldn’t have guessed it had happened only once before in the live ball era.

After the jump, more on rookies who establish themselves only to get traded mid-season.

One of the best kept secrets of the 2013 season was this – among only a handful of previous occasions, this season ended with two players having current 13 year or longer streaks of 20 or more stolen bases. Those players were Ichiro Suzuki and Juan Pierre. And, if not for an injury-plagued 2010 season that held him to just 17 thefts, Jimmy Rollins would have been a 3rd player with that distinction.

Nolan Ryan was recently inducted into the HHS Circle of Greats and is one of these pitching greats with a career accomplishment unique among pitchers active since 1901. What is this unusual career feat?

Congratulations to Artie Z! He correctly identified our quiz players as the only Hall of Fame pitchers active since 1901 who hit no more than 5 career home runs but did hit one off another Hall of Fame pitcher. More on this vanishing occurrence after the jump.

In a recent quiz, I happened to stumble upon a tiny subset of hitters, namely those represented by the yellow area in the extreme upper right-hand corner of the chart below. In that post, I noted the recent increase in the number of such hitters and speculated on what might be causing this uptick.

Pro football HOFer Ace Parker died Wednesday in his hometown of Portsmouth, Virginia. Parker played professionally in baseball and football in the 1930s and 1940s, continuing in pro baseball into the early 1950s. At his death, Parker was the oldest living US-born major-leaguer.

For 101 major league seasons (1901-2001), the players below were the only hitters to achieve a certain seasonal batting feat. In 2002, three more players achieved this distinction and, since 2002, 5 more players have done this a total of 7 times.

What is this batting feat peculiar to modern day hitters?

Hint: Versalles’ season is the one you’re thinking of.

Don’t know whether I stumped you or just no interest. Anyway, the solution is that these players and the others from the current century all have a low slugging percentage relative to extra-base hits. In particular, they are the only players since 1901 having a season with an extra-base hit total of over 160 times slugging percentage. The seasons are after the jump.
