PHILADELPHIA -- Phillies manager Pete Mackanin fought back tears on Sunday.

The 25,754 fans at Citizens Bank Park gave Mackanin a standing ovation as he swapped lineup cards at home plate for the final time as Phillies manager before the season finale against the New York Mets.

Mackanin and Mets manager Terry Collins, who also will not return to his position next year, exchanged hugs.

Mackanin tipped his cap to the crowd in acknowledgment as he returned to the dugout where Phillies coaches and players greeted him with handshakes. General manager Matt Klentak announced Friday that Mackanin has been reassigned and will become a special assistant to the GM in 2018.

The Phillies' capped their second-half resurgence with a happy send-off for their departing manager.

The offense came alive in the fourth inning, when Philadelphia scored six runs to spark an 11-0 victory.

Mackanin, who has managed Philadelphia the last 2 1/2 years, initially didn't realize the fans were cheering for him until bench coach Larry Bowa clued him in.

"My wife and son were in the stands in the second row, and I couldn't look at them," Mackanin said. "I knew my wife would be crying. I didn't want to start crying myself.

"It was very special feeling. Totally surprised me. I'll remember it forever."

Rookie outfielder Nick Williams' three-run inside-the-park homer in a five-run eighth inning was the exclamation point on the emotional day.

"I saw (third base coach Juan Samuel) over there waving. I got big eyes and was like, 'Sweet, let's do it,'" Williams said.

"I thought I had a piano on my back running."

The Phillies secured the No. 3 overall pick in next June's draft. The Mets finished with their worst record since 2009, when they also went 70-92.

Thanks to improved pitching and prospects who thrived, Philadelphia went 37-38 following the All-Star break after winning only 29 of their first 87 games.

The Phillies sent 11 batters to the plate during their six-run fourth inning.

Maikel Franco's three-run homer off reliever Chris Flexen broke the scoreless game. His 24 home runs led the Phillies this season.

Back-to-back bad defensive plays in the inning by Mets rookie first baseman Dom Smith kept the inning alive.

A charging Smith couldn't handle Phillies starting pitcher Nick Pivetta's routine sacrifice bunt, failing to field the ball cleanly and then threw it away on his toss to first base. A run scored on the error, and on the next pitch, Smith again bungled the play.

After fielding Cesar Hernandez's ball, Smith tossed it to pitcher Flexen, who was nearby but not covering first base, instead of second baseman Gavin Cecchini. J.P. Crawford scored on the play for a 5-0 lead.

The Phillies added another run on Odubel Herrera's single to right field.

Mets starter Noah Syndergaard pitched two scoreless innings, walking one batter and striking out two. Syndergaard's workload was limited in his second outing since returning from a torn right latissimus muscle that caused the right-hander to miss nearly five months.

"I felt like today was the best I ever in my entire life," Syndergaard said. "I felt like I owed all my success to (pitching coach) Dan (Warthen). It really helped me out a lot. I was able to clean up my delivery a little bit. Today was the best I ever felt in terms of pitching ever and I'm excited by the way that I finished up the season."

Pivetta limited the Mets to two hits in five shutout innings. He worked around five walks and struck out seven on 98 pitches.
