Harris will lose his place on the active roster to make room for Eduardo Rivera, who is expected to start Saturday's game against the Mets. Harris went 0-for-2 with a hit-by-pitch during his lone appearance after getting called up to Boston on Thursday and has gone just 3-for-18 at Worcester since joining the organization June 30. He will likely spend most of what's left of the year in the minors.

Harris was acquired from the Athletics late last month and will now join the Red Sox after he slashed .336/.441/.537 across 178 plate appearances with Triple-A Las Vegas prior to being dealt to Boston nine days ago. The veteran has less success in a much smaller sample at Worcester, however, producing a .167 average and .583 OPS in 20 plate appearances.
