CHICAGO — With slightly more than seven weeks still remaining, it’s already been a special season for Red Sox second baseman Dustin Pedroia.

Last night, Pedroia extended his road hitting streak to 28 games. With a hit this afternoon, Pedroia can tie Hall-of-Famer Tris Speaker, who holds the franchise record with a 29-game streak in 1913.

The hit last night meant that Pedroia now has the second-longest road hitting streak for a second baseman since 1956. He eclipsed Luis Castillo (27 games in 2002) last night and now trails only Cleveland’s Johnny Temple (33 games in 1961).

Meanwhile, Pedroia’s 10th homer of the season Friday night made him only the sixth Red Sox second baseman in the last 57 years to reach double figures in homers in a season.

The others: Felix Mantilla (twice), Mike Andrews (twice), Mark Bellhorn, Ted Lepcio, and Todd Walker.

Changing places

For the first time since 2003, when Grady Little managed the Red Sox, Jason Varitek hit ninth in the Red Sox lineup last night.

“Since we had [Jacoby] Ellsbury ninth and [J.D.] Drew first,” explained manager Terry Francona, “rather than have our fastest get stuck behind our catcher, we’ll do this.”

The change also broke up the consecutive lefties in the batting order (Ellsbury and Drew) when the lineup turned over and makes it tougher for opposing teams to bring in a lefty reliever.

Varitek, though he entered last night’s game hitting only .221, has shown signs of life lately, hitting .316 (6-for-19 with six walks) over his last 16 games.

“I think he feels better,” said Francona of his catcher. “I know there’s been a lot of times when he’s come back to the bench, even on a ball that wasn’t a hit and say, ‘I feel better,’ which is good.”

End of a streak

Until Manny Delcarmen gave up a solo homer to Carlos Quentin to lead off the eighth inning Friday night, the Red Sox bullpen had put together a string of 18 consecutive scoreless innings.

The streak dated back six games and was the longest scoreless streak for the Boston bullpen since they stitched together 34 1/3 innings without a run allowed from Aug. 18-29, 2004.

Delcarmen also saw a personal streak come to an end. He had thrown seven scoreless innings over his previous seven outings. Moreover, over his last 14 appearances, Delcarmen has a 2.51 ERA (four earned runs allowed over 14 1/3 innings).

“He left a breaking ball up to the one guy [Quentin] you don’t want to do that with,” said Francona. “He’s good and he’s going to be better. But with young guys, that’s sometimes how it goes. I still believe in developing young relievers, because it’s cheaper.”

Costly play

White Sox starter Jose Contreras’ season came to an end in the second inning when the veteran right-hander suffered a torn left Achilles tendon while covering first base.

Ellsbury hit a roller to first and Contreras raced over to take the throw from first baseman Nick Swisher. But steps before he reached the bag, Contreras limped, then collapsed as he crossed the bag. Ellsbury was safe.

Contreras writhed on the ground in pain and had to be helped to his feet. At one point, perhaps sensing the seriousness of the injury immediately, he slammed his fist on the grass in frustration.

He left the game and was replaced by D.J. Carrasco. Two innings later, the White Sox made the announcement on the pitcher’s diagnosis.

Contreras, who is listed at 36, is under contract for $10 million in 2009. Typically, a torn Achilles tendon requires at least a year for recovery.

Paying tribute

The Sox announced plans to honor some former managers on the next homestand.

Joe Morgan, who led the team to two division titles, will be honored Wednesday in recognition of the 20th anniversary of “Morgan Magic.” Morgan replaced John McNamara at the All-Star break in 1988 and the Sox won their first 12 and 19 of their first 20 under Morgan.

Dick Williams, who managed the “Impossible Dream” 1967 Sox to the A.L. pennant and was recently inducted into the Hall of Fame, will be recognized Saturday.

Around the bases

Jed Lowrie extended his hitting streak to eight straight games with a two-out double in the second inning. … Friday night’s defeat marked the first time that the Sox had lost in a game in which Jon Lester had pitched at least seven innings. Until them, the Sox had been 13-0 in Lester’s career and 10-0 this season.
