The 8-8 Philadelphia Phillies will have to pick up the offensive slack and try and not lose the series to the 10-6 San Francisco Giants Tuesday night at Citizens Bank Park.

Here’s what to watch:

Lineup changes look to spark some offense

Manager Joe Girardi said Monday night that a lineup change could be necessary, and the Phillies’ starting nine sure does looks different for game two of the series.

Sitting are Andrew McCutchen, Rhys Hoskins and Didi Gregorius. Gregorius also missed Monday’s game because of swelling in his right elbow.

McCutchen, the Phillies’ regular leadoff hitter, is still in last season’s season-long slump. He is hitting .157/.306/.255 in 62 plate appearances and is three for his last 27. Matt Joyce gets the start for McCutchen in left field and leads off. Joyce does not have the speed of a normal leadoff hitter but Girardi likes his on-base ability. Joyce has a .388 OBP over his last 400 plate appearances.

Jean Segura, who has a 10-game hitting streak and is batting .405 over his last 12 games, bats second. He and Bryce Harper are the Phillies’ two hottest hitters at the moment.

Segura’s batted sixth or seventh in all but one game this season and the Phillies have needed that offense at the bottom of the order because they’ve gotten nothing out of the centerfielders in the 8-hole.

The Phillies as a team are hitting .234/.311/.363 this season.

Wheeler night

Since his Phillies’ starting pitcher Zack Wheeler struck out 10 batter and allowed a single hit in seven scoreless innings in his first start of the season, he hasn’t been the same. Wheeler is 0-2 with a 4.91 ERA since that day.

Wheeler has allowed 17 hits in those two starts, coming against the Atlanta Braves and New York Mets, respectively.
