Thanks to the new and improved Game Logs feature on FanGraphs, it's now amazingly easy to extract game by game data for a player, including wonderful peripherals. The first bit of data I wanted to examine closer is some context into exactly how badly Albert Pujols is struggling compared to the rest of his career.
After exporting his entire career game log, I grouped the data into 35 game sections or the entirety of what he's played in 2012. I made sure each range of 35 games was contained within a single year and did not last more than 40 calendar days so that an injury in the middle of a stretch wouldn't be included. Over his 11+ year career he's had 933 such 35 game periods as during a season several will overlap as the rolling 35 games adds a new game at the end and drops off one at the beginning.
The table below lists Albert's worst 35 game period for each season by OPS:
In his career, he's had 9 seasons where he never had a single 35 game stretch with an OPS below .800 and in 2003 his lowest OPS over one of these periods was .995(!). His only two below .700 have come in the last two seasons, with 2012 as the runaway winner in terms of being terrible. His .510 OPS is 162 points than his next worse and 265 points lower than his next worse after that.
What really astounds me is how low his OBP is during his current season compared to all previous years. In 933 samples, only twice was his OBP below .333, his current .235 and a runner up in 2011 at .322. These same two awful periods are his only two with an AVG below .250 in his career, a .248 in 2011 that's 51 points higher than his current .197.
From a power outage standpoint, his current .077 ISO isn't his career worst. In 2011 he had an .075 that was slightly worse, and 2011 was filled with several stretches of overlapping periods with very poor ISOs. Outside of 2012, 2011, 2010 and a few rough patches in 2007, he's never had any periods with an ISO below .195.
Here's a Google spreadsheet with all 933 different 35 game periods of his career.
