Yanks sweep a good sign or mirage?

The weekend sweep of the Reds injected some life into the Yankees’ playoff hopes. The key from here on out, according to Joe Girardi, is to continue to rack up wins in the Bronx.

“If we’re going to get to the playoffs, we’re going to have to win at home because we have so many games [here],” Girardi said after the Yankees beat the Reds on Sunday to clinch a three-game sweep.

With three straight home wins over Cincinnati, the Yankees improved to 21-23 at home. The Bombers are three games into a 10-game home streak, one that is viewed in some corners as a crucial test for their playoff hopes.

Really, the next slice of schedule gives the Yankees a nice opportunity to open up some ground.

Ten of their next 13 games are against Texas and Boston -- two teams that began play in last place in their respective divisions.

The Yankees will take the field Monday three games back of Baltimore in the AL East and one and a half games back of Seattle for the second Wild Card spot.

With 37 of their final 64 games at home, Girardi & Co. will need to win consistently in the Bronx to make the postseason.

The Yankees' weekend sweep of Cincinnati was a strong start, of course. But it doesn't mask the fact that they went 18-23 at home before the All-Star break.

So was the weekend a sign of things to come -- or a mirage that masked the team's glaring flaws?

Question: Can the Yankees play well enough in the Bronx in the second half to make the postseason?
