Dioner Navarro, predicted to be Welington Castillo‘s backup in the upcoming season, wasn’t signed to be the kind of player that wins games for the Chicago Cubs, but he came up big Sunday in Arizona. In his only at-bat, Dioner Navarro came to the plate with two men on, and blasted a three-run home run off of San Francisco Giants pitcher Matt Cain, who would pitch only one inning due to being struck by a line drive from Cubs left fielder Alfonso Soriano.

Navarro’s knock proved to be three-fourths of the run production for the team, as they edged out the Giants by a score of 4 to 3. Although it was a bit of reduction in production from the 11 run effort the Cubs made in their game against the Los Angeles Angels, any win is something we’ll take. In addition to Navarro’s impressive blast, Soriano had two hits, and star shortstop Starlin Castro went 1-for-2.

On the pitching side for the Cubs, Jeff Samardzija allowed one run in two innings of work, and new reliever Kyuji Fujikawa pitched a scoreless inning in relief that included two strikeouts. Carlos Marmol struggled in his sole inning of work, walking one and allowing a double that drove in one run.

The next game on the schedule for the Cubs in the preseason is Monday, when Dale Sveum‘s squad will face off against the Los Angeles Dodgers at 2:05 PM.
