Carlos Rivero

Rivero signed a minor league contract with the Red Sox prior to the 2014 season and played at Double-A Portland and Triple-A Pawtucket, slashing a combined .264/.324/.379 in 105 games. Primarily a third baseman, Rivero also played shortstop and left field while with the Sea Dogs and PawSox. He finished 2014 with a five-week stretch in Boston, getting just eight plate appearances in four games played. Those eight plate appearances earned him a distinction, though. He went 4-for-7 with two doubles, a homer and a walk for a 1.911 OPS, the highest OPS in major league history for a player with at least six plate appearances. Despite that honor, Rivero was waived in the offseason and claimed by Seattle. The Mariners non-tendered Rivero but brought him back on a minor league deal with a spring training invite.
