Chicago: Travis Wood rode to the rescue with four innings of hitless relief while Jason Heyward delivered a go-ahead RBI single as the Chicago Cubs extended their winning streak to six games with Monday’s 2-0 victory over the Los Angeles Dodgers.

Wood got an emergency call in the third inning after starter Jason Hammel experienced cramping in his right hamstring as he warmed up.

Meanwhile, Matt Harvey threw seven shutout innings of two-hit ball in his best start of the season and Neil Walker’s leadoff home run in the bottom of the seventh snapped a scoreless tie and lifted the New York Mets to a 1-0 win over the Chicago White Sox on Memorial Day.

Harvey began the afternoon with the second-highest ERA in the National League at 6.08, but he looked like the Harvey of 2013 on Monday. The right-hander, who allowed one hit over nine innings in his only other start against the White Sox on May 7, 2013, retired the first 13 batters he faced before J.B. Shuck’s clean single to right.
