A pair of infielders, one from each team, could return to their respective lineups Wednesday as the Giants and Reds complete their three-game series. Cincinnati shortstop Zack Cozart, whose playing status is day to day with tendinitis in his surgically repaired right knee, is poised to return to action. San Francisco second baseman Joe Panik, recovering from a groin injury, also might be back on the field.
