Soriano by the Pitches
Hoping to understand Alfonso Soriano's hot and cold streaks this year, I turned to the incomparable Fan Graphs to break down his present and historical success against different pitches. The results suggest that Soriano is losing the skill that made him one of the more feared hitters in the game, but that he might have found a method to compensate for this loss. Below is a chart showing the percentage of fastballs Soriano has seen each year since 2005, with 2009 broken down per month. It also shows his ranking among hitters seeing the fewest fastballs, his "runs above average" number on fastballs, (wFastball) and how high he ranks among all hitters, and his overall OPS. (As in, not specific to fastballs) The most important thing to notice here is his wFB rank.

You probably have noticed a couple of striking trends going on here. First, Soriano has progressively moved from being one of the most effective hitters in baseball against the fastball to being quite pedestrian. Second, pitchers have not noticed and adapted to this change: They contiue to avoid throwing fastballs to Soriano as if he were the same hitter he was in 2005. He's not.
So how do we explain Soriano's April and July, when he hit like the hitter for whom the Cubs offered that premium contract?
Finding that answer requres looking at Soriano's results swinging at sliders.

It makes sense that if pitchers fear Soriano's ability to hit the fastball, they would throw him an inordinate number of sliders, and indeed the table indicates Soriano consistently sees among the most sliders in the game. Throughout his career Soriano has proven to be one of the weaker hitters against sliders.
This potentially could be a toxic combination: A fastball hitter who no longer can hit fastballs, and still doesn't see any fastballs to boot. But then look at the two months this year that Soriano has hit: April and July. The numbers indicate that Soriano's output isn't due to hitting fastballs with the authority to which he is accustomed; instead he's hitting sliders in a way that he previously did not. Well.
Of course, other factors might be at work as well, but if so I have yet to find an obvious candidate. Such marked changes do not appear when looking at Soriano's results against other pitch types. Neither does plate discipline seem to be the issue. Soriano is both swinging at fewer pitches outside of the strikezone this year, and making more contact when he does swing - both at pitches inside and out of the zone, and it shows no meaningful fluctuation from month to month in 2009. His BABIP shows severe fluctuations from month to month, but that appears to be driven by corresponding changes in his line-drive percentage, so there's nothing unusual there.
Assuming that these stats do reveal a truth about the real world (I know, I know), there are several questions to consider going forward. Most obvious, what is the cause behind Soriano's diminish returns against fastballs? Is it that he now has a "slider speed bat"? Is it a matter of approach at the plate, where he has stopped guessing fastball in order to better hit the breaking stuff? The latter can be fixed, the former, not so much. Looking at how consistent the downward trend is, my hunch is that it's the former, a slow erosion in the speed of his bat. If it's the former, and Soriano is losing some quickness in the swing, will we see him move away from his preference for heavy bats? And will he be able to compensate by consistently hitting sliders with the results found in April and July? Then, there are questions concerning how pitchers resond. At what point will pitchers adjust to the fact that Soriano does not hit fastballs with the authority he once did, and adjust their pitch selection? There may be a lot riding on these questions.
Update: I was unaware of it as I wrote, but less than a month ago R.J. Anderson at Fan Graphs wrote about how few fastballs Soriano sees. He doesn't mention either Soriano's historical trend of diminishing results on the fastball, or the weird fluctuations this year on the sliders; instead he reaffirms the notion that Soriano is a good fastball hitter and the problem is in the dearth of fastballs he sees. I think he may be wrong there, but I should at least try to be a good scholar and cite the work.
Drew Storen DFA'd by Bluejays. Another once interesting reliever who fell off a cliff. Bosio fixer-upper vs. irreparably broken?

An industry source told The Post that the Yankees had asked serious Chapman suitors — a list believed to include the Nationals, the Cubs and the Indians, as well as a mystery team — for their best and final offers. While that doesn’t clinch a trade of Chapman, the impending free agent, it makes such a transaction darn likely. The Yankees intend to hold onto Miller, who is signed through 2018.
I'm thinking mystery team is the Tigers or Giants
from Iowa yesterday in extended inning starts, Cahill was bad/Matusz was pretty good. Soler (0-3, walk), Coghlan (1-3, double, walk) did play in AA.
That's a hell of a first impression by Montgomery. Brian Cashman having a good laugh on that debut.
...and it's a 3 run homer.
hey, vogelbomb had a HR on his 1st game with SEA AAA, too!
montgomery comes on with men on 1st/2nd, 2 out, in the 8th.
"Tommy Stokke of FanRag Sports reports Chris Sale was sent home from U.S. Cellular Field on Saturday after cutting up throwback jerseys that he did not want to wear.
I thought the same. It'd be great luck to face these non-contenders after the trade deadline.
...why isn't j.lucroy playing for TEX yet?
2r HR on a 12-pitch AB.
nathan to join the cubs tomorrow.
Wow in deed.

Chris Sale was scratched from tonight's scheduled start due to a clubhouse incident before the game
he was sent home by the team, too. the wsox released a press statement and everything. they stated it was non-physical in nature.
He was scratched from his start today. No reason given.
At the start of the season the book was that he was trying to pitch to more contact so he could stay in the game longer and it seems to be working so far. Contact against is 77.5% this year and it was 70.2% the year before. He averaged 6.7 IP/game last year and so far it's 7 IP/game. His actual pitches per game are only down to 106.1/game from 107.2/game last year but if he's able to go a bit farther into games without throwing more pitches and without giving up more runs that is a good thing.
sale's skills and insane value makes it almost too hard to have a market for the guy...he's got 3/38m owed to him over 3 seasons (2 team options). he could easily pull in 30m/yr if he was on the market as a FA.
he's throwing a bit differently this season, especially with more sliders and less changeups like earlier in his career, but all his stuff still looks great even if the HRs are a little elevated and the Ks are down.
