New Arms 2010 - Group Two
We received 130 votes last week, and we'll be taking your votes again. I'm adding some write-in candidates, like Sergio Santos. Here's why -- if a pitcher has PITCHf/x data prior to his Major League debut in 2010, he's not making it through my filter. If you see a pitcher, like Santos, slip through...
New Arms: Tip of the Iceberg
The first few months of MLB action have yielded a bounty of new pitchers to check out. By "check out" I mean explore via PITCHf/x. The flood comes from two sources: your standard run of the mill rookies playing in the show and (non-)prospects pitching in preseason baseball. Exhibition ball in big...
New Arms of the Week: September 7-13
A week after the bumper crop, only four pitchers made their Major League debuts last week. If Tim Lincecum's back wasn't balky, it would've been three. Madison Bumgarner was called-up to start in place of The Freak. The Giants' prospect showed his true velocity (high 80s), surprising many (myself...

New Arms of the Week: Last of August
Closing out August, and adding a day to the "week", we have four rookie pitchers who debuted in the final week of August. Armando Gabino - threw some long relief made a brief start and was sent back down* Daniel McCutchen - snuck in on the 31st with a start Pedro Strop - hard thrower with two...
New Arms of the Week - August 10-16
Six rookies got the call and made their major league debuts this week. This will mostly be a run-down of their basic PITCHf/x numbers, but I have a few observations - despite the small samples. rookie pitch # vs LHH vs RHH MPH PFX_X PFX_Z DEG RPM Cesar...
New Arms of the Weekend: Tuesday Night Starters
Since the most recent edition of New Arms covered a good chunk of last week already, I'm left with what amounts to a preview of two of Tuesday's starters. After being thrown to the wolves in the Bronx, Junichi Tazawa draws the start for Boston, while Doug Fister gets the call for Seattle. Fister...
New Arms of the Week and a Half
Instead of just last week's rookie pitching debuts, I'm including Monday through Wednesday's debuts as well. Hello, Neftali Feliz. This is a pretty big batch of pitchers this time around, led by Feliz and one more fireballer, Waldis Joaquin. We get the Orioles' Brian Matusz and Chris Tillman, Bud...
New Arms of the Week: Five Righties

New Arm of the Week: Mat Latos
Mat Latos went from Futures to Majors in a week. Latos' debut with the Padres came on Sunday, making him the only rookie pitcher to make his debut in the weekend after the All Star break. Latos throws two fastballs (four-seam and two-seam), a breaking ball (let's call it a slider) and a straight...
