Pennington started at short and went 2-for-4 with his first career grand slam in Wednesday's 10-8 win over Oakland.
Pennington's heroic blast capped off a five-run comeback in the seventh inning over the Angels' division foe. It was just the 33-year-old's third homer of the season, so fantasy owners shouldn't overreact to his big night at the plate. Pennington was relieving Andrelton Simmons at short, but the majority of his playing time comes at the keystone against left-handed starters.
