CHICAGO -- Chicago Cubs starter Kyle Hendricks exited after two innings against the Los Angeles Angels on Saturday because of low back tightness.
The right-hander threw 43 pitches and gave up a pair of earned runs in the brief outing. He also gave up four hits and walked two in Chicago's 7-0 loss.
"It was just weird and I wasn't effective," said Hendricks, who added that he experienced spasms a day earlier. "It was smart not to push it any further."
Manager Craig Counsell said Hendricks will be evaluated further in coming days before the club determines if he'll need time on the injured list.
The 34-year-old Hendricks, who started the day 1-6 with a 7.48 ERA, was demoted to the bullpen in May after giving up 28 earned runs in his first five starts. He's the only remaining Cubs player who appeared in the 2016 World Series.
