After hours of storms forced the Red Sox and Mets to suspend Friday night’s series opener with New York leading 4-3 in the bottom of the fourth, the frenemy teams picked up exactly where they left off on Saturday afternoon.

Fenway Park had a chance to dry out, but the home team still looked waterlogged when the game resumed. The Mets never relinquished their lead from the night before, and won 5-4.

The innings played before the rain had been chaotic, and the mess continued on Saturday afternoon. The Boston bats came out strong in the first two frames, plating three runs on three hits, but the New Yorkers answered back immediately, with a leadoff doubles and 2-run homer in both the third and fourth.

With Friday’s starting pitchers Kutter Crawford and Kodai Senga unavailable for the resumption, both teams turned to their bullpens.

Alex Verdugo got back in the batter’s box; Senga had a 1-2 count against him when the game went into a delay on Friday night. Grant Hartwig took over for the Mets starter and needed just one pitch to complete Verdugo’s at-bat with a ground-out. Triston Casas followed with a 2-out single, but found himself picked off first base moments later.

18 hours after it began, the fourth inning was finally over.

While the Red Sox kept going down 1-2-3 or stranding the few runners they did get, the Mets threatened almost every inning. New York led off six of nine frames frame with a base hit, including three leadoff doubles.

Joe Jacques replaced Kutter Crawford, who’d started the night before and allowed four earned runs on four hits. The 28-year-old rookie reliever put two runners on with a pair of singles before getting back-to-back strikeouts to end the fifth.

In the sixth, the usually-lights-out Brennan Bernardino put the game further out of reach. He gave up a leadoff double to Pete Alonso, who promptly advanced to third on a wild pitch and scored on Brett Baty’s single, extending the Mets lead to 5-3.

Richard Bleier’s 1-2-3 seventh finally snapped the Mets’ leadoff hit streak. He remained in for the eighth, when his teammates helped the Mets loaded the bases without making an out, and helped the veteran lefty out of the jam.

“JT is playing second today because we want the offense… I just wanted the best offense out there today,” Cora said of Turner on Friday afternoon.

Unfortunately, the Red Sox manager didn’t get what he was hoping for from Turner on Saturday afternoon. He finished the contest 0-for-4, snapping his hitting streak at 15-games. It was the longest active hitting streak in the majors, and the second-longest by a Red Sox player aged 38 or older. (Ted Williams had a 17-game hitting streak in 1957.)

At times late in the game, putting Turner at second just to have him in the lineup looked like it wouldn’t pay off defensively, either. In the top of the eighth, when two balls hit in his direction got the better of him. Both were initially ruled singles, but looked and felt more like errors. Redemption came in the form of Turner igniting inning-ending double plays to keep the Mets scoreless in the eighth and ninth.

“It was a grind out there,” Cora admitted. “They put the ball in play in a lot of situations, they did a good job, but at the end, we turned double plays and that kept us in the game.”

If only the Red Sox lineup could’ve done something with the many chances they got. Jarren Dura, Casas, and Rafael Devers each had a 2-hit game, and therefore, accounted for three-quarters of their team’s hits.

Casas’ second career triple and subsequent run was a rare shining moment in an otherwise lackluster affair. The rookie first baseman’s progression this season deserves more recognition; over his last 26 games (dating back to June 13), he’s hitting .329 with a 1.006 OPS, 28 hits, six doubles, the aforementioned triple, five home runs, 15 runs, and 13 RBI.

“We didn’t really get a chance to get Senga on the ropes (on Friday night), so it wasn’t like we had a lot of momentum building, and we were coming in trailing a run,” Casas said. “We didn’t know who was starting until 10 minutes before the game (on Saturday), so that kind of threw off our routines, in terms of our preparations.”

“It was a little cat-and-mouse-y,” he added. “Overall, they played a good game. We couldn’t get anything going.”

All told, the lineup went 2-for-8 with runners in scoring position, stranding six. The only 2-out RBI of the game belonged to Yu Chang, in the second inning on Friday night.

“We didn’t make contact when we had to,” their manager said. “We had chances to cash in.”

The Red Sox are 51-47. They’ve lost three in a row (all to losing teams) after winning 11 of the previous 13, and their 5-game winning streak at Fenway is over.

“There’s a winner and there’s a loser every game,” Casas said with a rueful smile. “Sometimes, the ball doesn’t roll your way.”

The baseball season is a long one, but with the trade deadline a little more than a week away, the Red Sox situation is less than ideal.
