SAN DIEGO -- There was good news to be had Saturday as rookie second baseman Jedd Gyorko, who is on the disabled list with a strained right groin, had a busy day.
First, Gyorko hit in the cage for the first time since he landed on the disabled list Monday. Then, he briefly took ground balls at second base during batting practice.
"That's a good sign," Padres manager Bud Black said.
Gyorko, who sustained the injury last Sunday in Colorado, continues to get treatment on the groin strain. He is eligible to return June 25.
"It felt good," Gyorko said after hitting. "I'm not really sure what that means, though."
It means, in the short-term, that Gyorko will accompany the team to San Francisco for three games at AT&T Park starting Monday. He is scheduled to hit and take ground balls with an eye on making a Minor League rehabilitation stint shortly thereafter.
The Padres have gotten good production in Gyorko's absence from Logan Forsythe, who had a two-run single in the eighth inning of Friday's 2-1 victory over the D-backs.
On Friday, the team traded for utility infielder Pedro Ciriaco to give them depth and someone who could play shortstop.
Ciriaco got his first start at second base Saturday as Forsythe moved to left field when Carlos Quentin was a late scratch in left field because of discomfort in his left shoulder.
Quentin sits, leaving room for Ciriaco's debut
SAN DIEGO -- Left fielder Carlos Quentin was scratched from the starting lineup before Saturday's game against the D-backs, giving utilityman Pedro Ciriaco, in a roundabout way, his first start with his new team.
Quentin was in the original starting lineup but was scratched with what manager Bud Black called left shoulder discomfort.
"We don't want to press this right now; he thought he did it on a swing last night," Black said before Saturday's game.
In Quentin's place, Logan Forsythe moved from second base to left field, a position he has never played at the Major League level.
But Forsythe spent the winter in San Diego working out at Petco Park, where he also took fly balls and worked with first-base coach Dave Roberts, who works with the team's outfielders.
This move gave the Padres a chance to let Ciriaco, obtained Friday from the Red Sox for a player to be named later, a chance to make his first appearance with the team.
The Padres traded for Ciriaco to give them some infield depth with second baseman Jedd Gyorko on the 15-day disabled list with a strained right groin.
Padres prospect Portillo begins rehab
Right-hander Adys Portillo, the Padres' No. 5 prospect, began a Minor League rehab assignment Saturday night in Fort Wayne, Ind. He started the second game of Class A Fort Wayne's doubleheader against West Michigan, allowing two earned runs on eight hits in 2 2/3 innings. He did not receive a decision in an 8-7 victory by Fort Wayne over West Michigan.
Portillo had not pitched since tenderness in his right triceps sidelined him near the end of Spring Training. He is expected to make three total rehab starts as he works his way back to Double-A San Antonio, where he was scheduled to open the season before his injury.
Portillo went 6-6 with a 1.87 ERA in 91 2/3 innings with Fort Wayne and was an All-Star in the Midwest League a year ago. He bypassed Class A Advanced Lake Elsinore and was promoted directly to San Antonio late last season.
The Padres signed Portillo out of Venezuela in 2008. His fastball is one of the best in the Padres organization and can touch 100 mph. He also throws a good curveball and a changeup, but he needs to improve his command to be successful when he returns to the upper levels of the Minor Leagues.
• Mississippi State outfielder Hunter Renfroe, the No. 13 overall pick in the First-Year Player Draft, is playing in the College World Series in Omaha. His team defeated Oregon State on Saturday, 5-4, in the first game of the CWS for both teams. Renfroe was 1-for-4 and scored a run.
• On Saturday night, it did not appear that any of the Minor Leaguers at Triple-A Tucson with opt-out clauses in their contracts would do so. The deadline was Saturday. Eligible players included Tucson catcher Rene Rivera, outfielder Travis Buck and pitchers Sean O'Sullivan and Daniel Stange.
• Former Padres catcher John Baker was claimed off waivers by the Dodgers on Saturday. Baker was designated for assignment by the Padres on Monday. He was optioned to Triple-A Tucson on May 31 after catcher Yasmani Grandal came off the restricted list. After being claimed Saturday, Baker was sent to Triple-A Las Vegas, the Dodgers' top Minor League affiliate.
