Plouffe went 1-for-4 with an RBI single in Thursday's 5-1 victory over the Angels.
The veteran third baseman broke through with his first RBI of the season in the sixth courtesy of a single to deep center, and he's now hit safely in three of the first four games of the season. Plouffe tore the cover off the ball in his first spring with the A's, hitting .370 with three doubles, two triples, two home runs and 11 RBI over 17 games.
