PHILADELPHIA (AP) — Zack Wheeler struck out 11 in seven innings, Bryce Harper hit a three-run homer and Kyle Schwarber added a solo shot to help the Philadelphia Phillies complete a four-game sweep of the San Francisco Giants with a 6-1 win on Monday.

Harper went deep off Giants rookie Mason Black, spoiling the major league debut of the Giants right-hander, who pitched into the fifth inning against the team he grew up rooting for.

“I hope he enjoyed it with his family and his teammates and everything else, because you only get one debut,” Harper said.

This season’s Phillies are winning as much as the ones Black cheered for as a kid.

The major league-leading Phillies (25-11) won their sixth straight and have won 10 of 11 and 17 of 20 to open a three-game lead over Atlanta in the NL East.

The Phillies have also won 10 straight games at Citizens Bank Park, just two wins shy of matching the team record set in 2012. Philadelphia also set a franchise record with 11 straight wins against NL West opponents.
