Worth noting

• Infielder Ryan Jackson, who is with Triple-A El Paso, was in San Diego this week to have his sore right wrist examined. Tests revealed that Jackson has a wrist strain. He's on the seven-day disabled list. Jackson, considered a plus-defender at shortstop, can play third base and second base as well.

• Infielder Cory Spangenberg, who is with Double-A San Antonio, landed on the seven-day DL with concussion-like symptoms after sliding head-first in a game Tuesday. Spangenberg, who is considered the Padres' No. 19 prospect by MLB.com, missed six weeks with a concussion in 2012, so the organization opted to err on the side of caution this time around. Spangenberg was hitting .271 at the time of his injury.
