MESA, Ariz. — Jeff Samardzija’s sketchy spring took a good turn when he saw his former team Saturday. After giving up 18 earned runs in 19 innings in Cactus League play, the Giants starter dominated his Cubs in a 5-2 win at Sloan Park. Samardzija retired 14 of the first 15 batters he faced, and allowed two runs on six hits in six innings. He struck out four and walked none. Jesus Guzman doubled in Munenori Kawasaki for the Cubs’ first run in the fifth, and Addison Russell hit a solo homer in the sixth.
Critical
Manager Joe Maddon liked to hear that Jon Lester was dissatisfied with his Friday start, even though he threw five scoreless innings and allowed only two hits. “I love the fact that he’s that good of a self-evaluator,” Maddon said. “So that was the good part about it. But again, I was looking at his delivery. The velocity was good. He was just off.”
Shawons
Shawon Dunston Jr. and his father were in opposite dugouts Saturday. The Cubs’ minor leaguer walked in his only at-bat and played both left and right field. His father, the former Cubs shortstop, wore a black jersey as a Giants special assistant. They embraced on the field before the game.
$900!
Continuing their collection, the Harry Caray’s Restaurant Group spent $900 to buy the windshield that Kyle Schwarber broke with a February home run ball. Proceeds went to Paz de Cristo Outreach Center in Mesa.
Richard return
Clayton Richard got his second chance quickly. After giving up five ninth-inning runs Friday, he replaced John Lackey in the sixth. He allowed two inherited runners, giving up two hits in one inning.
