David Bote and Ian Happ homered, and the Chicago Cubs beat the Washington Nationals 6-3 on Tuesday night.

Chicago slugger Anthony Rizzo left the game because of tightness in his lower back, but the Cubs got enough big hits to come away with another win after pounding Jon Lester the previous day in his return to Wrigley Field.

The Nationals reinstated Corbin from the paternity list and optioned right-hander Paolo Espino to Triple-A Rochester. He will be returned to the taxi squad for the remainder of Washington's seven-game trip, which ends on Thursday.

Davies gave up three runs and seven hits. He exited after former Cubs infielder Starlin Castro homered leading off the sixth and Josh Harrison singled.

Corbin went five innings, allowing three runs and eight hits. The two-time All-Star rejoined the team following the birth of his first child, Weston Alan, last week.

Rizzo grounded out to end a two-run third against Corbin and did some stretches at first base prior to the fourth. Cubs manager David Ross and a trainer went out to check on him.

Rizzo remained in the game. But he couldn’t handle Kyle Schwarber’s grounder leading off the inning, resulting in an error.

He was replaced as a precaution in the fifth, with Bryant moving from right field to first base. Jason Heyward went in to play right and took Rizzo’s spot in the batting order.
