There are many ways to get on base, but none are as dangerous or painful as being hit by a pitch. Bruise Rate, or BRU, measures the rate of HBP per 600 PA—or about one season. Check out the active leaders in BRU.

In the last few days, four cornerstone players have either suffered injuries or their injury status has changed. In some leagues, their injury situations could determine who wins and who doesn't...

A new and improved xBA that includes hard-hit balls and the Spd metric.

Many thousands of words have now been written about Toronto's Jose Bautista. No worthwhile forecasting system should have predicted more than 18-24 home runs for him entering 2010. But were there any logical indications that he could have not only beat that forecast, but that he could have more than doubled it?

We compare pitchers' 2010 and 2011 year-to-date performances with swing strike percentages, looking for pitchers where the change in SS% indicates a change in Dom different from what has happened so far.

What makes a strikeout? The first picture that comes to mind for many of us is that of a pitcher (probably a closer) blowing the hitter away with his fastball. So what are the pitch attributes that lend themselves to strikeouts more than others? We set out to explore that question this week by looking at PITCHf/x data.

Back in 2009, we began a series of research articles looking at hard-hit data for both batters and pitchers. The research confirmed what you might expect—pitchers with lower hard-hit rates (HH%) generally had better results: higher Dom, lower hr/f rates, and subsequently, lower ERAs. However, at the time of that original research, we didn't have enough years of data to conclude whether pitchers actually had any control over their hard-hit rates. Now we do.

Hunting? In April? Absolutely. The following analysis focuses on the hunt for new closers, with specific focus placed on the timing of transition from one closer to another. Once the hunt is complete and we have satisfied our craving for saves, we will return to the picture above to see if it holds any hidden meaning after all.

In this article, we will outline a brief study of WP and HBP, how they connect to various other metrics, if at all, and how we might improve our ability to identify the pitchers we want — and don’t.

The baseball positions (other than pitcher) may be laid along a defensive spectrum. For players with long careers, they often tend to shift positions during their careers, but the defensive shifts are predominantly in the direction from more difficult to easier positions. Shifts in the other direction are less common for good reason: they "almost never work."
