A Saber-Slanted Baseball Community

Mike Fast with some cautionary advice to all you budding Pitch FXers out there.

I'm cross-posting this from THT since I know a lot of PITCHf/x analysts gather to talk shop here.

A PITCHf/x scouting report on the 2009 AL Rookie of the Year

This week at THT, I take look at Gil Meche's down year, in particular, his four-seam fastball.

Once a Cub, now a Pirate. Joe Kerrigan has made some changes. While it may look like it hasn't worked, I suspect there's some luck balancing out. And a few less strikes being thrown. Either way, too early to tell, but Hart has changed the mix.

Kevin Gregg put his splitter down for a few days and replaced it with a cutter. The splitter made its return Thursday, so I graphed all of the pitches (in aggregate, five types) thrown since the cutter's debut.

Thought I'd link this for two, related, reasons 1. Latos has thrown a lot more change-ups since his debut 2. As a result, it struck me that his fastball/change move a little like Rich Harden's do. They're facing each other in about an hour.

Brian Bannister uses PITCHf/x as a self-improvement tool.

A PITCHf/x "preview" of Rick Porcello. The man throws about 70% sinkers (give-or-take depending on the batter hand), and for good reason. His secondary pitches are four additional reasons to rely heavily on the ole' two-seamer.

A look at Pavano's improvements in 2009. Or, just one of his improvements, his sinker.
