With Koji Uehara doing a fine job in the role of closer, the Red Sox have just two other right-handers, Junichi Tazawa and Brandon Workman, working out of the bullpen. Farrell said left-handed reliever Craig Breslow is particularly useful, considering he can get lefties and righties out with regularity, but the team could still be in need.
The Red Sox would have a hard time nabbing a player off waivers considering their priority would be nearly last due to their place in the standings. Veteran relievers LaTroy Hawkins of the Mets and Kevin Gregg of the Cubs are rumored to be available and could be intriguing options if the right situation were to present itself.
"If there's someone out there that makes sense for us to acquire, we might see that," Farrell said.
If the Red Sox don't go fishing in the trade market, they can turn to their plethora of young talent.
With rosters expanding on Sunday, the likely position player candidates to earn a promotion for September would be catcher Ryan Lavarnway, infielders Brock Holt and Brandon Snyder, who is currently on a rehab assignment with Triple-A Pawtucket, and outfielders Jackie Bradley Jr. and Quintin Berry, who was recently acquired from Kansas City for Clayton Mortensen.
As far as pitching is concerned, the Sox appear likely to promote Jose De La Torre, Rubby De La Rosa and knuckleballer Steven Wright, all right-handers who have worked out of the bullpen in the Majors at some point this season.
Allen Webster remains a toss-up considering he's been used as exclusively as a starter and has been pitching particularly well of late. In six starts with Pawtucket since July 31, Webster has 41 strikeouts to 11 walks in 35 2/3 innings while posting a 2.52 ERA.
Farrell said he's expecting to add about eight or nine players to the roster in the final month, and it's unlikely the team would call up anyone who isn't expected to make some sort of impact.
Daniel Bard, who walked five of the six batters he faced in a Gulf Coast League game Thursday, was called "a work in progress," by Farrell.
