Jeff Samardzija hasn't looked right through his first three starts. On Saturday, the Giants and Samardzija decided to try and figure out what's physically wrong.

Samardzija was placed on the 10-day IL with a right shoulder impingement and will have an MRI on the shoulder, which was an issue throughout the 2018 season when he made just 10 starts. Left-hander Andrew Suarez was called up from the taxi squad to take Samardzija's spot. 

Samardzija has a 9.88 ERA through three starts and gave up three homers and five earned Friday night against the Dodgers. His fastball has averaged just 90 mph this season. 

"Jeff came out (Friday) and reported shoulder soreness and that he wasn't really able to get loose and let his pitches go the way he wanted to," manager Gabe Kapler said. 

It's possible that the pitch that grazed Kiké Hernandez to load the bases in the fifth inning will end up being Samardzija's last as a Giant. The Giants have 45 games left in their season and Samardzija's five-year deal is up after the final game. 

For now, the focus is on finding out what's keeping him from letting loose, and also filling a second open slot in the rotation. The Giants already are without Drew Smyly (finger strain) and seem poised to slide left-hander Tyler Anderson into that spot. They could patch it together in Samardzija's spot, or eventually turn it over to another veteran who is getting up to speed.

Kapler said right-hander Trevor Cahill threw three-plus innings at the alternate site in Sacramento and looked good. 

"He looked sharp with all his pitches and really carved," Kapler said. "It was among the better outings we've seen since we had Cahill."
