BOSTON -- Believe it or not, the addition of starter Andrew Cashner might be the only move the Red Sox make before the July 31 trade deadline.

After acquiring Cashner from the Orioles for two prospects Saturday, president of baseball operations Dave Dombrowski said the team could stand pat and not make any additional moves. Though the bullpen is an obvious area of need, the Sox could be content with filling the hole with internal solutions.

“We might (stand pat),” Dombrowski said. “I think it’s one of those where we’ll analyze and see what takes place. I know a couple of our (relievers) worked a lot before the break. We weren’t getting a lot of innings from our starters. We think the rest, perhaps, will help some of them. When you look out there, there’s a good core of guys we like.”

Dombrowski cited the addition of Nathan Eovaldi-- a converted starter who will pitch in a high-leverage relief role once he returns from the injured list-- as a major internal move for the Red Sox. Prospects Darwinzon Hernandez and Tanner Houck have been converted to relievers in the minors and could help at the big-league level, too.

“(Eovaldi) is an addition to our bullpen,” Dombrowski said. “We also added Steven Wright recently. I don’t know. I don’t know if we’ll do anything else in that regard. We kind of like some of our guys out there.”

The Red Sox are thought to be right up against the $246 million luxury tax threshold, which would make any significant moves unlikely. Dombrowski believes an upcoming 13-game stretch against the Yankees and Rays could determine how he approaches the end of the month.

“We like how our club looks, but we’ve liked how our club looks for a long time,” Dombrowski said. “I think we’re starting to play better.”

Dombrowski has now made just two external additions to his team since the end of last season-- Cashner and reliever Colten Brewer, who came over in a small trade with San Diego in November. Dombrowski doesn’t feel as though any more moves are absolutely necessary at this point.

“I can’t say we will or we won’t because I really don’t know,” he said. “We’ll just keep a pulse of what’s taking place— what we’re doing and who else may be out there that might make sense.”
