Rapid Reaction: Cubs 4, Giants 3

MESA, Ariz. -- Here’s a quick look at the Chicago Cubs' 4-3 win over the San Francisco Giants in their Cactus League home opener Sunday.

The good: Cubs starters had their bats going early on, continuing a trend in camp. Dioner Navarro hit a three-run home run in the first inning while the Cubs totaled four hits in the opening frame. Alfonso Soriano had two hard-hit balls for base hits before coming out of the game. Brian Bogusevic had two hits. Cubs relievers gave up one unearned run in the final six innings.

The bad: Jeff Samardzija admitted his slider wasn’t very good Sunday, but he vowed to work on it before his next start. Carlos Marmol walked the first batter he faced on five pitches. That runner came around to score on a double by Pablo Sandoval.

What we learned: Navarro showed some pop with his home run, a shot to right field. After hitting just two long balls in 73 plate appearances he needs to show the Cubs he can hit. Recently he said he wants to use this year to re-establish himself as a big league player. Sunday wasn’t a bad start.

Sori buzz: During the game it was announced that Curtis Granderson of the New York Yankees would be out up to 10 weeks with a broken forearm. Should the Yankees look outside for a replacement, Soriano said he’d have to “think about” any trade offers, but he wants to win with the Cubs.

What’s next: The 2-0 Cubs take on the Los Angeles Dodgers on Monday in Glendale.
