Clay Buchholz was charged with the loss Tuesday night because he gave up a home to Evan Longoria in the eighth inning. But Drew Pomeranz said the responsibility was his.

He gave away a 3-1 lead in the seventh inning when No. 9 hitter Luke Maile belted a two-run homer. For Pomeranz, that is what lost the game.

“This one’s on me,’’ he said. “That’s a tough way to lose. I was pitching so well. It just really sucks sometimes when that one pitch comes back to bite you.’’

Pomeranz had thrown 91 pitches through six innings and seemed in control of the game, having allowed one run on three hits. He gave up a leadoff single to Tim Beckham then got two outs.

Fatigue was not a factor. Pomeranz had worked into the seventh inning eight times this season and thrown 100-plus pitches 12 times.

“I felt fine. I went out there and got those two outs. I just needed to get that last one,’’ Pomeranz said.

Pomeranz got ahead of Maile, 1 and 2. The lefthander intended to bounce the curveball, the same strategy he used to strike Maile out in the fifth inning. But he left the pitch up.

“Right into his bat,’’ Pomeranz said.

It was the second career homer for Maile, a rookie who was selected in the 43d round of the 2009 amateur draft by the Sox. He went to the University of Kentucky instead and was taken by the Rays in the eighth round three years later.

Despite the home run, Pomeranz has a 2.70 ERA in his last six starts.

Wright on track

Steven Wright, who will start Wednesday afternoon, expects to be much sharper this time around.

Wright came off the disabled list to face the Royals on Friday and gave up five runs in the first inning on a pair of home runs. The Sox lost the game, 6-3.

Farrell thought Wright was having issues with his release point in the first inning. But Wright felt it was more a matter of overthrowing after going 21 days between starts.

“When you have three weeks off in the middle of the season, you never get that,’’ Wright said. “You never want to get that much time off because that means something happened. That messes with your routine.’’

Wright, who turned 32 on Tuesday, is 13-6 with a 3.18 ERA. He will be facing the Rays for the first time in his career. Only four of their players have faced the knuckleballer before.

Not Tebow time

The Red Sox had two scouts at the workout held by former NFL quarterback Tim Tebow at the University of Southern California.

The 29-year-old former quarterback ran, took fly balls, threw, and hit before a large crowd of scouts and media. Tebow, who last played baseball as a junior in high school, is hoping to make it as an outfielder.

If Tebow is signed, it won’t be by the Red Sox, based on the reaction of president of baseball operations Dave Dombrowski.

“One of the keys is you do your due diligence in the organization. We did ours and there are a lot of guys who can look great in workouts and there’s a difference when you play the game,’’ Dombrowski said on NESN.

“We did our due diligence. I don’t want to say anything negative because other teams are looking at him, but I don’t think we’ll be rushing out to make a signing.’’

Celebrating Jimmy Fund

The annual WEEI/NESN Jimmy Fund Radio-Telethon finished Tuesday with more than $3.5 million raised. There aren’t many better days at Fenway.

Amber DaRosa, a 17-year-old cancer survivor, threw out the first pitch to David Ortiz. Amber was photographed with Ortiz in 2004 when, as a 6-year-old, she was being treated for leukemia. Now healthy, she met Ortiz again and they hugged before she fired a strike.

Simmons College student Katerina Mesa, a native of Miami, performed the national anthem and received a big ovation from the crowd. She recently completed treatment for a brain tumor.

Roster plans

Rosters can expand up to 40 Thursday. Farrell said the Sox would call up a group of players from Triple A Pawtucket in time for Friday’s game at Oakland. A second group of players will be added once the minor league season ends Monday . . . Ryan Hanigan was the DH for Single A Lowell and went 2 for 4 with a walk against Hudson Valley in an 8-4 victory. Hanigan was 6 of 14 in four injury rehab games with four walks and four RBIs. The catcher will rejoin the Sox on Wednesday and travel with the team to the West Coast. He is set to be activated Friday . . . Andrew Benintendi was recently fitted for a custom brace for his sprained left knee. That will be delivered next week. For now, he is doing rehabilitation work . . . Dustin Pedroia was 1 for 3 with a walk after missing two games to attend the funeral of his father-in-law. He is 34 of 75 (.453) since moving to the leadoff spot Aug. 10.

Good company

Xander Bogaerts’s double in the sixth inning was his 500th career hit. He joined Tony Conigliaro, Bobby Doerr, Tris Speaker, and Ted Williams as the only Red Sox players to hit that mark before turning 24 . . . Pawtucket first baseman/outfielder Chris Marrero was selected to the International League postseason All-Star team. Through Monday, the 28-year-old Marrero was hitting .287 with an .845 OPS. He had 23 homers (third in the IL), 69 RBIs (fourth), and 52 extra-base hits (first).
