BOSTON -- Shane Victorino, once again battling lower back stiffness, was out of Thursday night's lineup for the Red Sox' game against the Astros.
Victorino didn't run out a ground ball to shortstop because of the back pain in the sixth inning of Wednesday's 6-5 win and was replaced the next inning by Daniel Nava. The Sox had Nava in right field Thursday night, with Mike Carp in left.
"He's day-to-day,'' manager John Farrell said of Victorino. "How long this takes, we're hopeful it's only a couple of days. But given the fact that he's had this [twice] within the week, we've got to be a little bit more cautious this time around. He felt it [Wednesday] in that final at-bat, so by no means are we going to take a risk here.''
With Victorino unavailable, the Sox had just four healthy outfielders for Thursday's game: Carp, Nava, Jacoby Ellsbury and Jonny Gomes. The only other outfielders on Boston's 40-man roster are Jackie Bradley Jr. and Alex Hassan.
Hassan is on the disabled list at Pawtucket because of a calf strain and Bradley, who was optioned last week, can't be recalled until 10 days have passed unless the Sox place a player at a corresponding position (outfielder) on the DL.
"If we need, we can get through [Thursday's] game and we can adjust accordingly,'' said Farrell. "But Jackie wasn't eligible to come back, and . . . we felt like we'd stand pat and take the best bat that was available at Pawtucket and Ryan [Lavarnway, recalled on Thursday] is that guy.
"The roster is another issue that we've got to contend with.''
