Santana went 3-for-5 with a double, an RBI and a run scored in Sunday's 9-1 win over the Cubs.
The first baseman has recorded just two multi-hit efforts in 20 games in August, and he's drawn just eight walks in that span for a .274 on-base percentage. It's clear Santana is in a slump, which has lowered his season slash line to .226/.335/.373 with 17 home runs (none since July 24), 59 RBI, 59 runs scored and two stolen bases. Despite the slump, he's been in the starting nine on a nearly daily basis, as Ryan O'Hearn hasn't done enough to challenge for more playing time at first base.
