The Los Angeles Dodgers have picked Alex Wood to start a possible Game 4 of the NLDS against the Arizona Diamondbacks, which means Hyun-Jin Ryu was left off the roster.

"If there is a Game 4, Alex Wood will start Game 4," Roberts said.

Wood had a 2.72 ERA during the regular season.

Ryu will still travel with the Dodgers in the event of an injury. The left-hander had a 3.77 ERA during the season.

"Although he's had a tremendous season, just seeing the role out of the pen, he's not comfortable with it," Roberts said. "So I think that as we go through matchups and looking at the roster, Alex is the clear choice to start Game 4."
