BOSTON -- Thus far, the Red Sox have added a starting pitcher (James Paxton) and a right-handed-hitting catcher (Danny Jansen) in advance of Tuesday’s 6 p.m. ET Trade Deadline.

But the glaring need -- bullpen help -- is the one chief baseball officer Craig Breslow will be scrambling to fill over the next two-plus days.

In Saturday night’s 11-8, 10-inning loss to the Yankees at Fenway Park, the urgency of adding at least one more reliever only increased.

Coming out of the All-Star break, the Red Sox have gone 2-6, with bullpen struggles (seven blown saves in eight opportunities) serving as a culprit in four of the six defeats.

In the past eight games, Boston relievers have a 7.96 ERA over 31 2/3 innings, allowing 13.1 hits per nine innings, 5.97 walks per nine and an opponents’ batting average of .346 with a 1.052 OPS.

“I mean, it's tough, but we’ve got to do the job,” said Red Sox manager Alex Cora. “We got the baton to the ninth inning, and we didn’t finish it.”

Typically, Kenley Jansen is one of the best at taking that baton and seizing the moment.

But for the second straight Saturday, Jansen blew a save. He is 20-for-23 on the season. With two outs and a runner on second in the top of the ninth, Jansen was up 0-2 on Trent Grisham -- just one strike away from putting his team in the winner’s circle.

Strike three never came. On the sixth pitch of the at-bat, Grisham got just enough of a 94.8 mph cutter to serve up a classic Fenway double off the Monster to tie the game.

“Just go with my best pitch right there,” said Jansen. “Didn’t execute and got tough love today at the Monster, but it’s a tough loss. You’ve just got to move on from it and come back tomorrow.”

The expected batting average for Grisham on the fly ball that just eluded Tyler O’Neill in left was .090.

“That's an out in any other place,” said Cora. “We just play here.”

Of late, the problems go beyond bad luck. It’s a combination of attrition (Chris Martin and Justin Slaten remain on the injured list with right elbow inflammation), the starters not going deep enough into games (Kutter Crawford went 4 2/3 innings while allowing eight hits and five runs on Saturday) and other relievers being in the midst of untimely slumps.

“It’s what's going to keep me up at night, not being able to give my team a full five and even six [innings],” said Crawford.

While Crawford was surging heading into the All-Star break, he has been belted around in his past two starts, allowing eight home runs in 9 2/3 innings.

“Physically, I felt pretty good,” Crawford said. “But obviously, execution mechanically wasn’t there. First inning, I left some pitches in the middle of the plate. I think that's why this outing is kind of frustrating, because I do feel pretty good physically. Just didn't execute pitches.”

And that left the bullpen in charge of 16 outs, including the extra frame. That wound up being too much.

Once Jansen couldn’t finish the Yankees off, Cora decided to hold back relievers Cooper Criswell and Greg Weissert for Sunday and go with low-leverage righty Chase Anderson in the 10th.

Anderson was tagged for three runs (two earned), including a two-out, two-run double by Gleyber Torres.

“At the end, they did what they did, and where we’re at bullpen-wise, we needed Chase to go in there and finish the game,” said Cora. “So a tough one, but I think we battled.The pitching part of it, we will be better. Let’s go back to the drawing board and be ready for the next one.”

The Red Sox are fortunate to have All-Star ace Tanner Houck lined up for Sunday night’s rubber match.

Meanwhile, Breslow is on the clock in an effort to bolster the bullpen so nights like the one O’Neill had on Saturday (two homers, four RBIs) won’t be washed away.

“I know Bres and the team, they're working hard to try and get something going,” said O’Neill. “I haven't been up to date on any transactions or anything going on there, but I know they're working hard, so hopefully they can come away with something and bolster us a little bit, and we’ll see what happens.”
