Gonzalez is out of the lineup for Monday's game against the Orioles.
Gonzalez had been included in the lineup in four of the Red Sox's last five games, but three of those starts came against left-handed pitching. The 29-year-old looks like he'll have to settle for more of a part-time role versus righties, especially while Masataka Yoshida (1.117 OPS in July) is swinging a hot bat.
