CAPE ELIZABETH — Marshall Peterson showed that the early-season elbow tendinitis that plagued him is a thing of the past.

The big right-hander dominated from start to finish Wednesday afternoon, pitching Cape Elizabeth to a 1-0 baseball victory over Greely.

Peterson faced just two hitters over the minimum in a one-hitter. He struck out seven, and allowed only a third-inning single to Austin Nowinski.

“It was pretty impressive that he was able to come out and pitch like that today,” said Cape Elizabeth Coach Andrew Wood. “This is our eighth game and Marshall had only pitched eight innings all year coming in because of some arm trouble.

“He’s our ace and it was good to see him back out there like that.”

After a fielding error to open the seventh and a sacrifice bunt that pushed the potential tying run to third, Peterson got a weak pop out before getting a strikeout to end the game.

His final strikeout was the only one a Greely hitter managed a swing on. Five of Peterson’s six looking strikeouts came on his biting curveball.

“The curveball felt really good in warm-ups,” said Peterson. “I kind of knew it was going to be on. I just felt comfortable spotting it, and wasn’t worried about throwing it any (time in the) count.”

Peterson’s ability to mix things up was a big factor.

“He just really located well on the black,” said Greely Coach Derek Soule. “He set up those pitches nicely. He was working in and out. It would have been one thing if he was just pounding away – we would’ve been able to handle it a little more – but the way he’d go inside, outside, and mix his pitches, he just really set up those strike-three calls.”

The Capers (7-1) spotted Peterson the run in the bottom of the first. Brendan Tinsman (1 for 1, two walks) singled with two outs. With the count 2-2, Tinsman took off for second on the pitch and came all the way around to score when Dylan Roberts (1 for 1, walk, hit-by-pitch) unloaded a double to left field.

Starter Caleb Normandeau was tremendous for the Rangers (5-2-1) from there, surrendering just three more hits and striking out seven in the complete-game effort.

“Both pitchers were locked in from the first inning on,” said Soule. “It was just one of those days where if either side could string a couple hits together it was going to be the difference in the game. They were fortunate enough where they did it in the first inning.

“Peterson did a super job, just gotta tip your cap to him. Caleb almost matched him inning for inning.”

Matt Riggle, Pat McDonald and Bryce Hewitt each singled for Cape Elizabeth, and Nate Ingalls made a diving catch in center field to steal a second potential hit from Nowinski.
