The other pitchers include right-handers Greg Burke, Matt Buschmann, Gabe DeHoyos, Will Inman, Mat Latos, Edwin Moreno, Oneli Perez, Mark Prior and left-handers Arturo Lopez and Nick Schmidt.
Prior, who will earn $1 million is he's on the Major League roster, has been working out at PETCO Park and is on track to compete for a job this spring. Prior last pitched in the Major Leagues in 2006.
Position players who have been invited include catchers Eliezer Alfonzo, Mitch Canham and Colt Morton; infielders Peter Ciofrone, Chris Burke and Kyle Blanks and outfielders Chad Huffman and Cedric Hunter.
Burke, 28, played six positions last season with Arizona -- four positions in the infield and both corner outfield spots. He hit .194 in 86 games, and Towers thinks he is a much better hitter than that and that moving around as much as he did never allowed Burke to get comfortable.
Burke is a career .241 hitter over 445 games in his five Major League seasons with the Astros (2004-07) and D-backs (2008).
"He's a scrappy player who runs well and a solid defender," Towers said. "He has played behind [Craig] Biggio in Houston and [Orlando] Hudson in Arizona. I don't know if he's ever really gotten a chance to show what he can do.
"Even though it's a non-roster deal, we feel like he's got a chance to be on our ballclub."
Towers likes the fact Burke is a right-handed hitter and has mashed left-handed pitching to the tune of 50 points higher (.274) than right-handed pitchers. Towers indicated that he wouldn't rule out the possibility of Burke playing the outfield, especially against a tough left-handed pitcher.
Then there's Blanks, a first baseman who isn't on the 40-man roster, only because he doesn't have to be protected yet. But he's as highly regarded a prospect as the Padres have.
Blanks has had consecutive seasons of more than 20 home runs and 100 RBIs and figures to get a lot of playing time at first base in Spring Training with Adrian Gonzalez playing for Mexico in the World Baseball Classic.
