Rapid Reaction: Cubs 2, Mets 1

CHICAGO -- The Chicago Cubs beat the New York Mets 2-1 on Tuesday night at Wrigley Field. Here's a quick look at the game:

How it happened: Nate Schierholtz drove Anthony Rizzo home with a single to right with two outs in the bottom of the ninth for the win. A Curtis Granderson run-scoring sacrifice fly in the first inning had held up until Chris Coghlan tied the score 1-1 with a solo home run against reliever Josh Edgin to lead off the bottom of the eighth. It was Coghlan's first homer since May 28, 2013. Before that, the Cubs were stymied by starter Zack Wheeler. They managed two hits off him, both by Schierholtz. Wheeler walked two and struck out seven and was never in danger. Jake Arrieta got through 4 2/3 innings, and gave up one run while throwing 105 pitches. He grinded out of a bases-loaded, no-outs jam in the third, then Brian Schlitter helped him in the fifth.

What it means: The Cubs came close to being shutout for the fourth time in their past six games but pulled it out late. With catcher Welington Castillo shelved because of a rib cage injury, it's going to get even tougher to score runs, given that backups John Baker and Eli Whiteside aren't potent hitters. Baker is hitting .154 after an 0-for-3 night. Top-of-the-lineup players such as Anthony Rizzo are also struggling. Rizzo struck out three times against Wheeler, after striking out in his lone at-bat before being ejected on Sunday. But he came through against a lefty in the ninth. Starlin Castro was 0-for-4. The Cubs need some more offense -- badly. The bullpen, however, provided great in relief of Arrieta and threw 4 1/3 clean innings. The relievers have become a strength after a weak start to the season.

Fujikawa update: Injured reliever Kyuji Fujikawa threw on Monday at extended spring training in Arizona and had a good day, according to general manager Jed Hoyer.

"It's been an up-and-down rehab process," Hoyer said. "But yesterday was certainly a positive."

Up next: Edwin Jackson (3-5, 4.81 ERA) takes on Daisuke Matsuzaka (2-0, 2.54 ERA) in Game 2 of the series on Wednesday.
