<p>CHICAGO — The Cubs placed outfielder Jason Heyward on the 10-day injured list Thursday with a left hamstring strain.</p>
<p>Heyward, 31, left Wednesday night’s 4-3 loss to Washington in the fourth inning. He is batting .183 with four homers and 13 RBIs in 39 games.</p>
<p>“Hamstrings are always iffy, but seems to be on the milder side,” manager David Ross said.</p>
<p>Chicago also recalled outfielder Nick Martini from Triple-A Iowa before its series finale against the Nationals. The 30-year-old Martini is beginning his second stint with the team this season.</p>
<p>Martini started in right field against Washington. First baseman Anthony Rizzo returned to the lineup after he left Tuesday’s 6-3 victory over the Nationals because of tightness in his lower back.</p>
