MIAMI (Interstat) — Bryce Harper hit a solo home run, Aaron Nola pitched six scoreless innings and the Philadelphia Phillies edged the Miami Marlins 1-0 on Monday night at loanDepot Park.

Harper finished 3-for-4 with a double, single and his seventh homer of the season, providing the lone run in the third inning. The Phillies (15-20) took three of four games in the series and improved to 6-1 under interim manager Don Mattingly.

Nola (2-3) rebounded from two consecutive rough outings, allowing five hits and striking out five without a walk. He had given up 11 earned runs over nine innings in his previous two starts, including a 4 2/3-inning, six-run outing at Atlanta on April 26. Against Miami, the right-hander worked efficiently, throwing 82 pitches and retiring the side in order in the fourth and fifth innings. He struck out Christopher Morel, Joe Mack and Owen Caissie among his five punchouts and allowed only one runner to reach second base.

Miami (16-19) also collected seven hits but could not push a run across. Marlins starter Janson Junk (2-3) matched Nola for much of the night, allowing one run on five hits over 5 1/3 innings while striking out six. He walked none and kept Philadelphia off balance until Harper’s decisive blow.

The decisive moment came in the top of the third. After Trea Turner grounded out and Kyle Schwarber popped out, Harper drove a 2-1 pitch from Junk over the right-center field wall. Adolis García followed with a single, but Brandon Marsh grounded out to end the inning. It was the only run of the game.

Philadelphia threatened again in the sixth when García singled with one out, but Marsh popped out to third baseman Graham Pauley in foul territory and Bryson Stott lined out to right field. The Phillies stranded seven runners overall, going 0-for-6 with runners in scoring position.

Miami’s best scoring chance came in the sixth. Jakob Marsee led off with a sharp single to right field. Kyle Stowers grounded out to second, moving Marsee to second, but Otto Lopez grounded out to third to end the inning. In the third, Marsee singled with one out but was caught stealing second by catcher Garrett Stubbs. In the seventh, Xavier Edwards reached on a fielding error by shortstop Turner, but the Marlins could not capitalize as Tanner Banks induced a forceout and struck out Christopher Morel. In the ninth, the Marlins put two aboard against Brad Keller. Stowers singled with one out off a deflection by Turner. Otto Lopez then grounded into a double play, shortstop Turner to second baseman Stott to first baseman Harper, but Edwards followed with a single to right. Liam Hicks grounded out to second to end the game.

The Phillies’ bullpen combined for three scoreless innings. Banks worked a hitless seventh with one strikeout. José Alvarado pitched a perfect eighth with one strikeout, and Keller earned his second save with a scoreless ninth despite allowing two hits. Miami’s bullpen also was sharp: Lake Bachar tossed two scoreless innings, allowing one hit and striking out one; Calvin Faucher worked a scoreless eighth with one hit allowed and one strikeout; John King retired the only batter he faced in the seventh.

Philadelphia’s offense scratched out seven hits. Harper’s three-hit night led the way. García had two singles. Brandon Marsh, Garrett Stubbs and Alec Bohm each added one hit. The Phillies struck out 10 times but drew no walks.

Miami’s Kyle Stowers had two hits, including a single in the first and another in the ninth. Marsee singled twice. Otto Lopez, Christopher Morel and Xavier Edwards each had one hit. The Marlins struck out seven times and did not draw a walk.

The attendance was 7,626. The game lasted 2 hours, 35 minutes.

Philadelphia won the series opener Friday 6-5, lost Saturday 4-0 and won Sunday 7-2 before Monday’s shutout. The Phillies have now won three of their last four games after losing seven of their previous nine. Miami has lost two of three and three of its last five.

Nola’s bounce-back performance was a key storyline. In his previous two starts, he lasted a combined nine innings and allowed 11 earned runs on 13 hits. Against the Marlins, he scattered five singles, struck out five and did not walk a batter. He threw 56 of his 82 pitches for strikes. Junk, meanwhile, allowed a first-inning double to Harper and then retired eight of the next nine batters before Harper’s homer. He left after giving up a one-out single to García in the sixth.

The Phillies return home Tuesday to open a three-game series against the Athletics. Miami hosts the Baltimore Orioles for a three-game set starting Tuesday.
