Solis hopes he's dressed for success with Padres

LOS ANGELES -- Expanded rosters in September can be difficult on the Dodgers' visiting clubhouse staff members, who on Tuesday had to forfeit a back room where they usually dress to accommodate two players that the Padres added to their roster.

One of those players was 24-year-old catcher Ali Solis, who would have likely dressed in a broom closet if it meant he could be on the big league roster.

"Welcome to the big leagues," Solis said, motioning to where he was dressing.

The Padres added four players to their active roster: Solis, reliever Brad Boxberger and infielder Andy Parrino. Boxberger and Parrino were with Triple-A Tucson and have been on the Padres' roster before.

Another pitcher, Anthony Bass, was reinstated from the disabled list.

The team also designated catcher Eddy Rodriguez and pitcher Ross Ohlendorf for assignment to create room on the 40-man roster for Solis and Bass.

For Solis, who is a native of Mexicali, Mexico, located about two hours east of San Diego, his next Major League game will be his first one.

It's been a long road since the organization signed him as a 16-year-old. He hit .283 with six home runs and 40 RBIs this season with Double-A San Antonio and played in the Futures Game as a replacement for Yasmani Grandal, who was summoned to the big leagues in late June.

"What a great story," Padres manager Bud Black said.

Solis, a favorite of the Padres' player development staff for his attitude, work ethic and ability to work well with pitchers, was stunned when his manager, John Gibbons, told him last week that he would be added to the Padres' roster.

"I was excited. I was shocked a little. But I'm up here to enjoy this and try and help the team," Solis said.

Solis said he benefited from the tutelage of Gibbons, who spent 10 seasons as a Minor League catcher with parts of two seasons in the big leagues.

The Padres now have three catchers on their roster with Solis, Grandal and John Baker.

"He helped me a lot all season," Solis said. "He's a tremendous manager. I had a great time there. He helped me with blocking balls, my [catching] stance. He knows a lot about catching."

This will be Boxberger's fourth stint with the Padres this season. He has a 3.52 ERA in 15 1/3 innings. Parrino, who can play anywhere in the infield, hit .174 in 92 at-bats this season with the Padres but spent most of the season in Tucson, where he hit .328.

Padres benefit from improved confidence at plate

LOS ANGELES -- The results vary from day to day, but hitting coach Phil Plantier said that he's generally seeing better at-bats from the Padres.

There were the season-high 20 hits the team had in Sunday's loss to the Rockies. And then Monday, there were 10 hits in an 11-inning loss to the Dodgers.

But it's not just the sheer production and better at-bats throughout the lineup -- one through eight -- that have impressed Plantier the most during the Padres' second-half uprising, especially during the month of August, when the team was 18-10.

It's the improved confidence more than anything, he said.

"Overall, the guys' expectation of themselves is better than it was earlier in the season," Plantier said. "And it's allowed them to string together more quality at-bats."

Short hops

• All-Star closer Huston Street threw in the bullpen before Tuesday's game against the Dodgers with manager Bud Black and pitching coach Darren Balsley watching closely. "Huston feels great, his arm feels fine, his delivery is fine," Black said. "The concern is his ability to field his position." Street had a setback with his strained left calf on Thursday. There's no timetable as to when he'll try to run on it again.

• Carlos Quentin, who was a late scratch Monday because of right knee irritation, was in the lineup on Tuesday and in left field. Quentin lined out to center field as a pinch-hitter in the Padres' 4-3 loss in 11 innings on Monday to the Dodgers.
