YARMOUTH, Mass. — Three weeks ago, on the Fourth of July, the Brewster Whitecaps defeated the Harwich Mariners and pulled within eight points of the No. 1-seeded Yarmouth-Dennis Red Sox.

Brewster (23-8-3) defeated Y-D (25-7-1), 5-1 at Red Wilson Field, bringing the top seed in the East Division clearly into sight. The Whitecaps sit just two points behind the Red Sox with six regular-season games remaining.

With their fourth straight win, the Whitecaps avoided a season sweep and placed all the pressure on Y-D. The Red Sox own the head-to-head tiebreaker, but another meeting awaits on Friday, July 31, at Red Wilson Field. It will take another full-team effort for Brewster to beat Y-D again, at Red Wilson no less.

Y-D scored first in two of the teams’ first three meetings, and Saturday afternoon proved to be no exception. The Red Sox capitalized on a Holden Pantier (Georgia Tech) error in the fourth inning, scoring the opening run in front of an invigorated home crowd.

The Whitecaps entered Saturday hitting .296 over the final three innings of games, while Y-D mustered only a .214 batting average over the same span. Those numbers came into effect when the game reached its most vulnerable portion, and right when Brewster scored the runs that eventually secured the win.

Will Baker (Georgia Tech) opened the sixth with a single before Edward Yamin IV (LSU) walked and Jacob Lee (Virginia Commonwealth) was hit by a pitch. With the bases loaded, Pantier singled into right field to score Yamin and tie the game. Brewster grabbed the lead an inning later.

After Cash Strayer’s (Florida) leadoff walk, manager Jamie Shevchik opted to bunt with catcher Owen Jenkins (Texas Tech). Jenkins squared around and plopped a move-him-over bunt toward third. When third baseman Kevin Takeuchi (Southern California) fielded the ball and threw to first, Jenkins reached safely, and the throw skipped away.

Strayer took off from first and went all the way to third on the error. The heads-up baserunning allowed Brody DeLamielleure’s (Florida State) double-play grounder to score Strayer without much struggle.

Yamin walked again to open the eighth before pinch runner Tryston McCladdie (Clemson) stole second. Michael Torres (Miami) reached on another Y-D error, allowing McCladdie to score. Lee followed with a single before Pantier’s sacrifice bunt brought Torres home. DeLamielleure added an RBI single to score Lee and extend the lead to four.

Across all nine innings, no Whitecaps player collected more than one hit or scored more than one run. Still, Brewster racked up eight total base knocks and five runs in the season-critical win.

“It is like the monkey off your back,” Shevchik said. “It is a psychological thing that [the team and I] talked about before the game today. You go out, and you beat Y-D, they lose [their second in a row], and they feel they are no longer invincible. It gives some confidence to our guys that they can win a game against the best team in the conference.”

The confidence Shevchik talks about shines bright in the late innings, but it does not begin with Brewster’s late-inning offense. It began on the mound.

Blaine Brown (Tennessee) set the tone with two hitless innings, striking out five of the six batters he faced. The Volunteer has eight strikeouts in the nine batters he has faced this season, a mind-boggling stat by itself. The left-hander retired Y-D in order twice, allowing Brewster to settle into the contest despite its early offensive silence.

Zach Kmatz (Oregon State) took over in the third and handled the bulk of the afternoon’s work. The right-hander allowed two hits and one unearned run across four innings, striking out three without issuing a walk.

Y-D’s only run came after Brewster’s lone error, but Kmatz refused to let the inning spiral. After the Red Sox moved another runner into scoring position, he induced a groundout to escape the fourth with the game still within one swing.

“If you throw strikes, the hitters will hopefully get themselves out and keep your pitch count down,” Kmatz said. “When you walk guys, that’s when your innings dwindle.”

Kmatz practiced exactly what he preached. He threw 34 of his 49 pitches for strikes and retired the final seven batters he faced, keeping Y-D hitless across the fifth and sixth innings.

Noah Thigpen (Troy) finished the job with three hitless innings for his first save of the summer. The right-hander worked around two walks, struck out one and protected Brewster’s lead as the offense gradually pulled away.

Brown, Kmatz and Thigpen combined to allow only two hits and one unearned run. They struck out nine, walked two and held the East Division’s highest-scoring team without a hit over the final five innings.

“[Today] was kind of like an early playoff game,” Pantier said. “You only get to play so many playoff games in your career, so if you get an extra one, it’s awesome.”

The Cape Cod Baseball League postseason begins Aug. 4 with best-of-three divisional semifinals. If Brewster remains in the East Division’s top two, Stony Brook Field will host the opening game of the series. Catching Y-D would give the Whitecaps home-field advantage throughout the East playoffs.

Before another trip to Red Wilson, Brewster returns to Stony Brook for a Sunday matchup against the West Division-leading Bourne Braves. With both teams positioned for postseason runs, the 4:30 p.m. contest offers another opportunity to measure Brewster against one of the league’s best.

Saturday afternoon felt like an early playoff game, but Sunday could look like a preview of the championship round.
