Pillar is in the second year of arbitration eligibility and won’t become a free agent until 2021.
Recently hired president of baseball operations Farhan Zaidi added two outfielders to the Giants’ 40-man roster, but is reportedly still looking for a major-league contributor who could platoon with left-handed prospect Steven Duggar in an attempt to remain competitive while rebuilding.
Pillar, who bats right-handed, has played six seasons with the Blue Jays since being drafted in the 32nd round of the 2011 draft. The 29-year-old, who is better known for his defence, has a career .261/.298/.398 slash line with 55 home runs, 230 RBIs and 69 stolen bases.
The Giants also drafted Blue Jays pitching prospect Travis Bergen in the Rule 5 draft on Thursday, the final day of the winter meetings.
