Pennington will start at shortstop and bat ninth Tuesday against the Cardinals, Jeff Fletcher of the Orange County Register reports.
Andrelton Simmons is slated for thumb surgery and could be facing an extended absence, so the door appears open for Pennington to play regularly at short for the Angels in the weeks and months ahead. However, Pennington is a .244 career hitter with little power or speed to speak of, and veteran Brendan Ryan, whom the team brought in from Washington, could steal occasional starts.
