Last Meeting ( Sep 18, 2015 ) San Diego 4, Colorado 7

Colorado third baseman Nolan Arenado is finishing a standout season with a red-hot bat and looks to add to his National League-leading RBI total when the Rockies host the San Diego Padres on Saturday. Arenado, who has 112 RBIs and ranks second in the NL with 39 homers, went 3-for-4 with one RBI as Colorado notched a 7-4 victory in the opener of the three-game set.

Arenado is batting .365 with nine homers and 17 RBIs in September and is one RBI away from matching the total of his first two major-league seasons combined. Right fielder Carlos Gonzalez went 0-for-4 in his return from a foot injury and is hitless in 12 at-bats over his last three games and 3-for-27 in his past seven. Colorado is 8-28 against left-handers and San Diego is starting Robbie Erlin on Saturday - the first time all season the Padres have started a left-hander. Padres left fielder Justin Upton returned from an illness and went 1-for-4 on Friday and is 5-for-16 with six runs scores in his past four games.
