NL Notes: Samardzija, Diamondbacks, Baer

The Cubs should trade Jeff Samardzija now rather than waiting, USA Today’s Bob Nightengale writes. With Samardzija off to a hot start, his value should be at its peak, and the Cubs run the risk of having it drop if they wait. Even with Samardzija, the Cubs are in last place, so he’s unlikely to have a strong impact on their fortunes over the next year and a half unless they trade him. Here are more notes from the National League.

• With Tony LaRussa in the fold, Kevin Towers’ fate with the Diamondbacks is unclear, but it’s very unlikely that the D-Backs will hold onto manager Kirk Gibson, Nightengale writes. Instead, they could turn to White Sox third base coach Joe McEwing or Cardinals bench coach Mike Aldrete to replace Gibson.
• Giants president Larry Baer could be a candidate for commissioner, John Shea of the San Francisco Chronicle writes. Baer isn’t saying whether he would be interested in the job, but Shea guesses the outgoing Baer would find it appealing, even though his current job with the Giants means a lot to him as a native San Franciscan. “He’d be crazy to give it up. He’s done a remarkable job in San Francisco,” an MLB source tells Shea.
