EXTRA BASES: Yasiel Puig, who is on the disabled list with a strained left hamstring, could play in minor league games while the Dodgers are in Milwaukee next week. The All-Star right-fielder is eligible to be activated from the disabled list on May 10, when the Dodgers are scheduled to play the finale of a three-game series in Colorado. Manager Don Mattingly said he expected Puig to be ready to be activated around that time. “Right now, it seems like we're on track,” Mattingly said. … Closer Kenley Jansen started his minor-league rehabilitation assignment by pitching a scoreless inning for Class-A Rancho Cucamonga. Jansen, who is recovering from a foot operation, gave up a hit and struck out one. He is expected to pitch in five or six more games in the minor leagues before he is activated. Mattingly said he is planning for Jansen to be the Dodgers' closer again at some point, but wasn't sure whether that would happen immediately upon his return. … In his first game at triple-A Oklahoma City, top prospect Corey Seager was two for five with a run batted in. A 21-year-old shortstop, Seager was promoted from double-A Tulsa earlier in the day.
