It was one of those days for the RubberDucks at Canal Park on Sunday afternoon.

In the course of a season, there will be a few clunkers along the way. Under mostly sunny skies — except for a couple of brief showers in the seventh inning — the Ducks suffered a lackluster 6-0 loss to the Harrisburg Senators before 6,964 fans.

Of course, Saturday’s 12-2 setback was also one of those. Third baseman Joe Sever, who has been with the Ducks since late 2015, can lend some perspective.

Sever, at 27 years and 10 months, is also the oldest player on the current roster and has experienced it all before.

“It’s not a good feeling, but it’s a long season,” he said. “We’ve been here. We were playing great before early in the year. No panic from us. It’s going to happen.

“We’re going to bounce back, get to Bowie and pick up where we left off early in the week.”

Sever has been the regular third baseman this season but has played second, first and outfield during his time with the Ducks. During spring training, he also played catcher.

“I’m just trying to add any tool I can to the arsenal,” he said. “And be ready for whatever they need.”

The first-place Ducks (43-33) lost two-of-three in the weekend series, and their lead over the second-place Senators is down to 1½ games in the Western Division of the Eastern League. They start a brief four-game road trip at the Bowie Baysox at 7:05 p.m. Monday.

Sever, who is hitting .292, singled with two outs in the ninth. It was one of just two hits for the Ducks. They were dominated by right-hander Sterling Sharp, who allowed only Sicnarf Loopstok’s third-inning infield hit in seven innings in his Double-A debut. He walked two and struck out five.

“It is what it is,” Ducks manager Tony Mansolino said. “They outplayed us. You play 140 games in a season, you’re going to have a series that you lose, and you don’t look all that good when you do lose it.”

Mansolino, who managed High-A Lynchburg in the Carolina League last year, saw Sharp pitch for Potomac there and said he wasn’t surprised how well he performed Sunday.

“I think anytime you get a young guy come up, a lot of times you’re going to get the best that they’ve got that first time out,” Mansolino said. “The strike zone was a little bit big, too. He pitched well, took advantage of it and made it really tough on us.”

Ducks’ right-hander Aaron Civale (4-2, 2.60 ERA) struggled through 4⅔ innings. He allowed a run in the fourth and stranded two runners. But Matt Reistetter led off the Senators’ fifth with a home run, Alec Keller singled and scored on Carter Kieboom’s double. Following a hit batter and double-play grounder, Austin Davidson doubled in Kieboom for a 4-0 lead.

Civale was relieved by Carter Milbrath after walking Hunter Jones. It was Civale’s fourth start since returning from a monthlong stint on the disabled list for right shoulder soreness.

But Mansolino said that was not the issue Sunday.

“He’s in early-season form and the hitters are in midseason form,” Mansolino said. “You’ll start to see Civale and [Triston] McKenzie — the guys who missed a lot of time early on — see them kind of hit their stride in the next couple starts and really help us out.”
