Heineman spent this past season with San Francisco and appeared in 15 games for the Giants. Originally an eighth-round pick by Houston in 2012, Heineman has a .285 average in his eight years in the minors. In 2019, at Miami’s Class AAA New Orleans affiliate, the switch-hitting Heineman batted .341 with a 1.019 OPS in 48 games. He made his major-league debut that same season.
Signing Heineman adds depth for the Cardinals’ roster and does not signal or change anything about the team’s intent to pursue Yadier Molina’s return or have Andrew Knizner positioned as his likely backup.
