Ryu, who came to the Dodgers from Korea via a six-year, $36-million deal after the Hanwha Eagles accepted the Dodgers' $25 million bid, retired Blake Tekotte on a ground ball back to the mound and struck out Gordon Beckham to open the third. Dewayne Wise, celebrating his 35th birthday, launched a hanging curve to right for a triple, but the L.A. left-handed hurler retired Jeff Keppinger on a fly ball to left to end the inning.
Dunn, meanwhile, had made a Spring Training priority out of trying to attack opposing pitchers earlier in the at-bat in a move to raise his average and cut down his 222 strikeouts from last season. After working the count full and then grounding out in the first against Greinke, Dunn drove a 1-0 pitch from Peter Moylan out to left with Alex Rios on third in the fourth.
"In the first at-bat, I kind of wanted to swing early. Kind of get some stuff going, and he made some good pitches," Dunn said. "I just happened to go 3-2, and that last at-bat was something I was just going to try to get a pitch and the location I was looking and swing at it."
Greinke, signed to six-year, $147 million contract this past offseason, started for Los Angeles and worked two scoreless innings, striking out Wise and Rios in the first. Erik Johnson, one of the young hurlers for the White Sox getting spot-starts in this first week of Cactus League action, pitched three innings and yielded just one run on four hits while striking out two and walking one.
"It felt good to get out there against some real competitive players and hitters, and getting out there in a big league game," Johnson said. "I'm thankful for the opportunity."
Up next: The White Sox plan to take a look at their up-and-coming young starters during the first week of this extended Cactus League schedule. And while Hector Santiago certainly is young at 25 years old, Monday's starter in Scottsdale vs. the Giants (2:05 p.m. CT) has a bit more experience than Erik Johnson or Nestor Molina, who are bracketing him in the rotation. Santiago looks to have a roster spot locked up, but depending on John Danks' continued progress from Aug. 6 arthroscopic shoulder surgery, he could begin as the team's fifth starter. Addison Reed, Nate Jones and Jesse Crain also are scheduled to throw.
