New Arms of the Week - First of June

This week we introduce nine young pitchers from three countries. PITCHf/x data after the jump.

Antonio Bastardo (PHI) Undrafted Free Agent 2007 - 9/21/85 Hato Mayor, Dominican Republic - Started 2009 closing games in Double-A and made two starts in the Majors this week

Tommy Hanson (ATL) - 22nd round 2006 Riverside Community College - 8/28/86 Tulsa, OK - We've seen Tommy's PITCHf/x before thanks to an exhibition start in April; the only shock about his call-up is that it coincided with the release of Tom Glavine

Blake Hawksworth (STL) 28th round 2001 - Bellevue Community College - 3/1/83 North Vancouver, BC - Second stint in Triple-A Memphis was a big improvement over 2008

Steven Jackson (PIT) 10th round 2004 by Arizona - Clemson University - 3/15/82 Eutawville, SC - Waived by the Yankees in May, was part of the Randy Johnson trade in 2007

Matt Maloney (CIN) 3rd round 2005 by PHI - University of Mississippi - 1/16/84 Sandusky, OH - Known for his command, acquired from the Phillies in 2007 in the Kyle Lohse trade

Vin Mazzaro (OAK) 3rd round 2005 - Rutherford High School - 9/27/86 Hackensack, NJ - Proved tough to hit in his second brief stint in Triple-A and was a two-start pitcher this week for the A's

Travis Schlichting (LAD) 4th round 2003 by TB  - Round Rock High School - 10/29/84 Denver, CO - Drafted as an infielder, the Dodgers are his third team, and first to call him up

Jess Todd (STL) 2nd round 2007 - University of Arkansas - 4/20/86 Kilgore, TX - Moved to the bullpen for 2009, had 32 K and 7 BB in 24.1 innings for Memphis; played in 2008 Futures Game, so this isn't his first look via PITCHf/x

Wes Whisler (CHA) 2nd round 2004 - UCLA - 4/7/83 Noblesville, IN - Not overwhelming stuff (just 4.8 K/9) but attractive Triple-A ERAs (3.92, 2.81)
