A fan casually walked to home plate and approached Philadelphia hitter Brad Miller for a handshake before being apprehended, and the Phillies later beat the Pittsburgh Pirates 2-1 Sunday on Rhys Hoskins' home run in the 11th inning.

Moments after Bryce Harper argued a called third strike and Hoskins spiked his bat after being hit by a pitch, things turned bizarre in the sixth inning at PNC Park.

That's when a man carrying a cellphone came out of the crowd and strolled toward Miller in the batter's box. Miller backed away and the man kept walking, leisurely getting near the Phillies' dugout on the first base side, where he was handcuffed by security personnel and led away.

Miller then grounded into an inning-ending double play.

Hoskins hit his 21st home run, connecting off Chris Stratton (1-3). The drive came right after Harper again seemed displeased with plate umpire Ben May when striking out looking to start the inning.

Phillies reliever Ranger Suárez (3-0) got Starling Marte to ground out to end the 10th, stranding Adam Frazier at third, and worked around a hit in the 11th.

Drew Smyly made his first start with the Phillies, allowing one run and four hits in six innings. He also struck out.

The 30-year-old lefty was 1-5 with an 8.42 ERA in nine starts and four relief appearances this year for Texas, which released him on June 25. Smyly signed a minor league contract with Milwaukee on July 1, went 1-0 with a 4.97 ERA in three starts for Triple-A San Antonio, then on Thursday exercised his right to be released.

Pirates starter Dario Agrazal allowed one run on three hits with five strikeouts in six innings. The 24-year-old rookie has given up a combined eight runs (seven earned) in 28 innings through his first five starts.

ROSTER MOVE

Phillies: RHP Fernando Salas was designated for assignment to open a roster spot for Smyly. Salas (0-0, 6.75) allowed two runs on eight hits in 2 2/3 innings across three appearances for Philadelphia this season. RHP Nick Pivetta moved to the bullpen to make room for Smyly in the rotation.

TRAINER'S ROOM

Phillies: Segura left after the top of the fourth inning because of heel soreness. He was 0 for 2 before Scott Kingery moved from center field to replace Segura at shortstop.

UP NEXT

Phillies: RHP Aaron Nola (8-2, 3.77) starts at Detroit on Tuesday. Since last losing in a 2-1 defeat against Miami on June 21, Nola is 2-0 in five starts while allowing seven runs (six earned) in 32 2/3 innings.
