COL@SD: Richard blanks Rockies over six strong frames

PHOENIX -- It appears that Clayton Richard is ready for action.

The left-hander is expected to be activated from the disabled list for Monday's series opener against the Mariners in Seattle.

"He came out of his bullpen fine," Padres manager Bud Black said. "It looks as if Clayton is tracking toward Monday."

Edinson Volquez, originally scheduled to pitch Monday, has been pushed back until Tuesday. Richard has been on the disabled list since May 5 with an intestinal virus.

"I'm definitely excited to be back with the team and I'm ready to pitch when I get the opportunity to," Richard said. "Everything has been going well and I've been feeling good. That's the reason for everything, to start feeling better, and it feels good to be on the right track."

Richard threw a bullpen on Friday at Chase Field. He's also made two rehab starts at Triple-A Tucson, going 0-1 with a 2.25 ERA with 12 strikeouts and no walks in 12 innings. He also tinkered with his arm slot during the Minor League stint.

"It was good to have a couple of outings and get that feeling back," Richard said. "Eric [Stults] and Jason [Marquis] are really keeping us in it and Volquez is coming back. He's had a couple of tough innings, but on the whole, he has done pretty well. I'm really excited to be a part of it again."

Richard is off to a slow start, going 0-4 with an 8.54 ERA in six starts for the season.

"We're hopeful that it's just a one-time thing," Richard said of the virus.

Steals leader Cabrera glad adjustments are paying off

SD@ARI: Cabrera swipes his 100th career stolen base

PHOENIX -- Padres shortstop Everth Cabrera says he's no longer the player he once was -- and that's a good thing.

"I'm really happy that the Padres have believed in me and kept their confidence in me," Cabrera said. "I've made some big adjustments on offense and on defense and it's paying off. It's my time. I'm not 22 anymore. I'm 26 and I'm gaining experience each year."

Cabrera led the National League with 44 stolen bases last year and leads the Majors this season, swiping his 19th bag of 2013 -- and 100th of his career -- in the first inning Saturday night.

"I'm getting a lot better leads than I used to and I'm more patient on the bases," Cabrera said. "Before, all I had in my mind was to 'go, go, go,' but now I'm waiting on the right time."

Cabrera burst onto the scene in 2009 but was slowed with inconsistent play and injuries in the two seasons that followed. Last year, he scored 49 runs in a career-high 115 games.

"Now, it looks like he has finally arrived both physically and mentally," Padres manager Bud Black said. "He's playing at a pace that good players play at. There's a lot of intensity yet there's a calmness and poise to his game that good players have. He's making good decisions. I attribute that to maturity and confidence."

But the question remains, could Black, a former pitcher, keep Cabrera from stealing second base? Could he pick Cabrera off of first base?

"I would have tried but hopefully, he would not have got on," Black said. "But everybody got on against me, so I would have had my hands full."

Worth noting

• Cameron Maybin (right wrist) began a rehab assignment with Triple-A Tucson on Friday and went 1-for-3 with a strikeout. He has been on the disabled list since April 17.

"Cam swung the bat fine and had some good bat speed," Padres manager Bud Black said. "We talked last week about him having somewhere around at least 30 (at-bats) and we'll gauge it from there. We're not going to put a hard number on it. He's been out for five weeks or so and we want to make sure the wrist is fine."

• Catcher Yasmani Grandal, who is serving a 50-game suspension, went 1-for-4 with a run scored for Tucson He is eligible to be activated Tuesday.

• Rookie second baseman Jedd Gyorko tied a rookie club record for home runs in May with five.
