Former Marlins teammates AJ Burnett and Ryan Dempster squared off in the middle game of the marquee interleague series of the weekend, at Wrigley Field. There was potential for a pitchers’ duel, if the “Good AJ” showed up, and if Dempster maintained the good control he’s shown at home thus far (almost a 4-to-1 K/BB ratio in 52 1/3 innings pitched at Wrigley this season).

That wasn’t to be, though. The game was tight and low-scoring, but more because both teams missed opportunities, rather than Burnett and Dempster dominating. Both pitchers followed the “bend but don’t break” M.O. Burnett allowed two runs, struck out eight and walked three in 5 1/3 innings pitched, while Dempster allowed only three runs while walking a season-high six batters, and struck out six.

The Yankees had their chances. They had base runners every inning, but were only able to push runners across in the third and sixth innings. In the third, Curtis Granderson led off with a single — doesn’t it seem like when the Yankees score, he’s in the middle of the rally? — and later scored on Robinson Canó’s double. Nick Swisher followed with a sacrifice fly to bring in Alex Rodriguez, who singled and advanced to third on the Canó double.

The Cubs tied the game in the fourth, making Burnett pay for issuing a leadoff walk to Blake DeWitt. Two batters later, Carlos Peña hit a laser into the right-field seats.

Sometimes, the most important moment in a game isn’t a timely hit, it’s a baserunning mistake. Following a one-out walk to Kosuke Fukudome, Starlin Castro lined a single to center. On that hit, Fukudome was running on the pitch but did not advance to third. On the FOX broadcast, Tim McCarver said there was “no excuse for Fukudome to not be on third base with one out, or at least get thrown out trying.” The next batter, DeWitt, who figured in the Cubs’ first rally, bounced into a 4-6-3, inning-ending double play.

Eduardo Nuñez carried the positive vibes from the solid turn of the double play into the top of the sixth, lining a single up the middle on an 0-2 count and later scoring on a Granderson sac fly to give the Yankees the lead. (The Granderson RBI was off lefty James Russell. Granderson, versus lefties this season: .277/.341/.651, 20 RBI.) In the ninth, Nuñez drove in what would be the go-ahead run with a double.

Mariano Rivera made things interesting, yielding a leadoff home run to Reed Johnson and a single to Alfonso Soriano. But he needed just four more pitches to record three outs, inducing Geovany Soto to ground into a double play and striking out Jeff Baker.

That would be the high-level overview of the game. Two plays in particular preserved this victory for the Yankees: the first was the double play that ended the fifth. The second came in the sixth inning. Canó missed an easy catch on a force attempt that turned a potential first-and-third, two-out situation into a bases-loaded, one-out scenario. On a full count, Soto lined to left. Brett Gardner made up for his base running gaffe in the top of the sixth by making a nice catch on the liner and firing a one-hop strike to home. A huge collision ensued between Peña and catcher Russell Martin. Martin hung onto the ball, showed it to both Peña and home plate umpire Sam Holbrook.

Sometimes over the course of a season, winning teams win games despite an odd boxscore. Saturday, the Yankees walked 10 times and only scored four runs. They got 11 hits and went 4-for-13 with runners in scoring position yet left 13 men stranded. They committed two errors and ran themselves out of an inning.

Yet in the end, the formula that usually leads to a victory — timely hitting, a few key defensive plays, above average starting pitching and a capable bullpen effort — put a W up for the Yankees. By all accounts, they should have beaten the Cubs about 11-3 in this game. But as the better team, being able to hang on and win the close game is encouraging and should serve them well as the season wears on.
