SAN DIEGO -- It's no accident that Padres center fielder Cameron Maybin's hot stretch at the plate has seen him use the entire field more than he did earlier in the season.

Maybin went into Wednesday's series finale against the Pirates at Petco Park with 10 hits in his last 13 at-bats over three games, with six of those hits going to either center field or right field.

"The saying is 'There are a lot of hits over there,'" said Maybin, a right-handed hitter who has two hits to right field and four to center field in this recent stretch.

Maybin, who is hitting .297 this month, has raised his average from .211 to .230 in the past three games. That's the highest his average has been since April 10.

"I'm just taking what they're giving me," Maybin said. "But the contact [rate] has been better and a lot of my hits have found holes. Sometimes they fall, sometimes they don't. But the biggest thing for me is to keep competing."

Maybin tied his career high with four hits in Tuesday's 7-5 victory over the Pirates in 10 innings. He had four hits two days earlier against the Giants.

Boxberger optioned to make room for Werner

SAN DIEGO -- The Padres officially added Andrew Werner, Wednesday's starting pitcher, to the roster on Wednesday and optioned reliever Brad Boxberger to Triple-A Tucson.

Werner, a 25-year-old left-hander, was 1-2 with a 5.79 ERA in four starts with Tucson. He started the season with Double-A San Antonio, going 4-8 with a 3.23 ERA in 18 starts.

Werner became the 14th starting pitcher that the Padres have used this season -- the most in the Major Leagues. The Rockies have used 13 starting pitchers.

In 2002 and '09, the Padres used 15 starting pitchers, though that number reflects starts by pitchers after rosters expanded after Sept. 1.

Boxberger has a 3.52 ERA in 15 1/3 innings, with 16 hits and 13 walks allowed to go with 20 strikeouts during two stints with the Friars.

"These guys are still growing," Padres manager Bud Black said of the rookie relievers on the roster. "In Box's case, it was some pitch sequencing, the ball-strike ratio. Those are the things that Brad needs to work on."

That said, Black still envisions a bright future for the 24-year-old Boxberger.

"He'll be a strong factor in our bullpen moving forward," Black said.

The Padres also designated outfielder Jeremy Hermida for assignment on Wednesday. Hermida was hitting .252 with three home runs and 22 RBIs in 44 games with Tucson. He made the Padres' Opening Day roster and hit .250 in 24 at-bats before landing on the disabled list April 28 with a strained left abductor.

Statue to be unveiled on Jerry Coleman Day

SAN DIEGO -- The Padres announced on Wednesday their plans to unveil a statue in honor of Hall of Fame broadcaster Jerry Coleman during the Jerry Coleman Day celebration on Sept. 15.

Jerry Coleman Day will celebrate his 70 years in baseball, 40 of them with the Padres. Those who are attending the game should be in their seats at least 30 minutes before the game starts (5:35 p.m. PT) to make sure they don't miss the pregame ceremony and a performance by the U.S. Marine Corps' Silent Drill Platoon.

"Jerry inspires all of us at the Padres every day," Padres president and chief operating officer Tom Garfinkel said in a release. "He's served our country in two wars and has been named World Series MVP, yet Jerry remains the most humble person you will ever meet. Through this tribute, we want to thank Jerry and honor him in a way that shows him how much he means to this community and everyone in the Padres organization."

The team also announced on Wednesday that there's been a change to the start time for that game on Sept. 15, as the game against the Rockies will now begin at 5:35 p.m. PT.

Short hops

• All-Star closer Huston Street, who has been on the disabled list since Aug. 11 with a strained left calf, played catch on flat ground before Wednesday's game and said he "felt great" and "didn't feel it [the calf strain] at all." There's still no timetable for Street's return, though it won't likely come before September.
