SAN FRANCISCO -- The Giants placed Joe Panik on the 10-day disabled list prior to Saturday's game vs. the Cardinals with a strained left groin and purchased the contract of infielder Chase d'Arnaud from Triple-A Sacramento.

Jeff Samardzija, who has been out since May 29 with shoulder tightness, was activated from the disabled list to make Saturday's start, right-hander Chris Stratton was optioned to the River Cats and right-hander Hunter Strickland was transfered to the 60-day DL.

Panik was injured while running the bases in the fourth inning of San Francisco's 3-2 victory over the St. Louis Cardinals on Friday night.

Panik prolonged the fourth inning with a two-out single off Cardinals right-hander John Gant that ended a personal 0-for-16 skid. Panik appeared certain to score on Gorkys Hernandez 's subsequent double to the left-field corner, but Panik pulled up at third base in obvious discomfort.

Panik's injury history thus continued to lengthen. He missed 31 games earlier this year after undergoing surgery to repair a left thumb ligament. He endured back inflammation in 2015 after making the National League All-Star team. Concussions sidelined him in 2016 and 2017, even while he ranked as the NL's toughest hitter to strike out.

Each of San Francisco's starting infielders, except for shortstop Brandon Crawford , has been on the DL this season.

"We've had to deal with enough of these this year," manager Bruce Bochy said.

Alen Hanson almost certainly will be the primary replacement for Panik, who has compiled a .240/.309/.345 slash line with four home runs and 14 RBIs in 54 games. Hanson possesses a slash line of .273/.305/.530 with six home runs and 24 RBIs in 46 games.

"He'll probably be more comfortable at one position. We've moved him around a lot," Bochy said of Hanson. "That's probably affected him a little bit.

"But we'll miss Joe."
