Padres' Nick Martinez replaces Kershaw on U.S. WBC roster

Major League Baseball announced Sunday that San Diego Padres pitcher Nick Martinez will replace Los Angeles Dodgers ace Clayton Kershaw on the 30-man roster for the United States for the World Baseball Classic.

Martinez went 4-4 with a 3.47 ERA in 47 games for San Diego last season, making 10 starts and collecting eight saves. He finalized a $26 million, three-year contract with the Padres in November.

Kershaw announced Friday that he wouldn't be able to participate in the WBC. The three-time Cy Young Award winner didn't specify the reasons that would prevent him from participating.
