Cashman: A-Rod will not be everyday infielder for Yankees

News: Yankees general manager Brian Cashman indicated Tuesday veteran Alex Rodriguez's days as an everyday infielder are over, and he's hopeful Rodriguez will be able to fill the role of full-time DH.

"I can't expect Alex to be anything," Cashman said during a phone interview Tuesday with The Associated Press. "Even before the suspension, he wasn't the same player at third base on the defensive or offensive side.

"We look forward to him hopefully solidifying himself as a tremendous DH for us."

The New York Daily News published a report Monday citing a source saying Rodriguez is determined to regain his role as an everyday third baseman. However, New York re-signed Chase Headley to a four-year deal to be the team's starting third baseman.

"In his mind, he’s still the third baseman," the source said. “That was before (Headley was re-signed) today, anyway.

"Based on what he was being told by the Yankees, Alex believed he would get the chance to play third base, and he believes he can do it. He’s motivated by it because he loves to play the field."

News: Tigers third baseman Nick Castellanos is focusing on improving his quickness during offseason workouts in order to improve defensively, Tigers general manager Dave Dombrowski said Tuesday at the Winter Meetings.

Castellanos committed 15 errors and had a .950 fielding percentage in 145 games at third base in 2014.

"His hands are solid and his arm is solid," Dombrowski said, per MLive.com. "He normally catches what he gets to, but we're looking to increase his quickness over there.

"There's no question, from a defensive perspective, that he needs to improve. But when I say that, we try to give him the benefit of the doubt. He hadn't played third base in a while."

Dombrowski also has confidence in Castellanos' offensive abilities after he hit just .259 with 11 home runs as a rookie.

"We think he has a chance to be a good offensive player," Dombrowski said. "He had a good solid year last year, and we think he's going to continue to get better. When you look at his numbers for a rookie, and in a pennant race, his offensive numbers were pretty good."
