With several Chicago Cubs already suffering injuries in camp (Matt Garza, Ian Stewart, Josh Vitters) and others working their way back from previous injuries (Scott Baker), if there is one player seemingly ready for the regular season -- and possibly a big one -- it’s pitcher Jeff Samardzija. After nearly getting his head taken off by a line drive up the middle, Samardzija got through his two innings of work in his Cactus League debut against the San Francisco Giants on Sunday in good fashion, and he knew what worked for him. “I think the fastball, splitter like we did today,” Samardzija said. “That’s a big combo for me. Speed ‘em up, slow ‘em down. Didn’t walk anyone, that’s exciting. And kept the ball on the ground.” Samardzija gave up one run on three hits but nothing was driven deep into the outfield. Plus, his slider was a mess. “Slider, last year was really key for me, for a strike,” he said. “Anytime in the count. Pulling it and leaving it up high like today (Sunday) was unfortunate. It’s a big pitch for me.” His catcher Dioner Navarro added: “I don’t he’s quite there yet but he threw some good pitches. His fastball was pretty good.”
