Rizzo (forearm) went 2-for-2 with a solo home run in a rehab appearance with Double-A Somerset on Tuesday.
Rizzo began his rehab assignment Friday and has gone 2-for-6 with two walks, two strikeouts and two runs through three contests. The veteran first baseman is closing in on a return from the 60-day injured list, and he took another step toward that goal Tuesday by playing first base after serving as the designated hitter in his first two games in the minors. Rizzo could immediately reclaim his starting role at first base upon his return to the big club, as Ben Rice has batted .063 with no extra-base hits and a 28.9 percent strikeout rate over 32 at-bats in August following a promising start to his big-league tenure.
