GLENDALE—Chad Billingsley has been working on his mechanics and saw positive results in his spring training debut for the Los Angeles Dodgers.Likely to be the No. 2 starter behind Cy Young winner Clayton Kershaw, Billingsley wants to smooth out his leg kick during his delivery. Monday was a step in the right direction as he pitched two scoreless innings in a 6-4 victory over the White Sox in an exhibition opener.Billingsley gave up a single to Alexei Ramirez and walked none. Ramirez finished with two of the Sox six hits.Billingsley said he felt good and mixed curveballs and changeups with his fastball. He’s looking for a stronger season than 2011, when he went 11-11 with a 4.21 ERA, his sixth with the Dodgers. The right-hander was an All-Star in 2009.The game also marked the unofficial debut for first-time manager Robin Ventura. He started a White Sox lineup that could foreshadow what he’ll use on opening day, with Alejandro De Aza leading off, followed by A.J. Pierzynski, Alex Rios, Paul Konerko and Adam Dunn.Dodgers star Andre Ethier hit a double in his first at-bat of the spring against Philip Humber, who allowed a run and a hit in two innings. He will likely be in the back of the White Sox rotation after he won a job as a starter a year ago. He went 9-9 with a 3.75 ERA in his first full major league season.Humber got five groundouts and praised the defense of second baseman Gordon Beckham and Ramirez at shortstop.Led by prospect Scott Van Slyke’s two-run homer, the Dodgers scored five times in the sixth off White Sox prospect Nestor Molina, acquired in the offseason trade that sent closer Sergio Santos to Toronto. Van Slyke is the son of former major leaguer Andy Van Slyke.He was the Dodgers’ minor league player of the year after he hit .348 to win the Double-A Southern League batting title. He also had 20 home runs and 92 RBIs.Molina, who might begin the season in Double-A, allowed five runs and seven hits in 1 1-3 innings.

NOTES—White Sox prospect Addison Reed struck out Matt Kemp in a 1-2-3 inning. … Dan Johnson, who could possibly make the Sox roster as a reserve, hit a two-run homer in the ninth off Ryan Tucker. … SS Dee Gordon led off for the Dodgers. He needed stitches in his lip Saturday after he took a grounder off the face during batting practice.
