Walker went 1-for-4 with a solo home run in Tuesday's 8-2 loss to the Rockies.
Walker's eighth-inning blast cut the deficit to four runs before the Rockies fired back with two more runs of their own. The first baseman has gone 11-for-38 (.289) with three homers and eight RBI over 12 contests since he returned from an oblique injury. It's shaping up to be a strong end of the year for the 33-year-old, who is slashing .257/.344/.487 with 26 homers, 79 RBI, 66 runs scored, 23 doubles and two stolen bases over 119 contests.
