Edit: New reader Sec. 210 rightfully asks for some explanation of these numbers. The numbers above are WV, or Win Value. Win Value is Run Value adjusted to reflect the score and inning of a game. RV is equivalent to runs (e.g. a solo home run is worth 1.0 RV). Win Value takes RV and mutiplies it by an adjustment factor. For example, the adjustment factor for the run that breaks the tie in the bottom of the ninth is 6.04, so a solo home run to win is worth 1.0 RV and 6.04 WV. In contrast, the adjustment for a solo shot by the leadoff batter in the top of the first is 0.61, so in that case, the RV is 1.0 and WV is 0.61.
Where do the adjustment factors come from? I try to explain that in this long post, as amended by this post. Short version: They are based on the effect each run has on the average team's probability of winning the game. The 6.04 WV means that play increased the teams chance of winning 6 times as much as the average run scored at any other point in the game. In contrast, the leadoff home run increased the chance to win by 6/10ths of the average run.
So, to answer Sec. 210's question, for the 5.89 WV, you can say that that play was worth nearly 6 times the average solo home run hit at any other point in the game. Or, that play helped the Nats win as much as the visiting team scoring 10 runs in the top of the first does. (i.e. add up all of the WV in the 1st inning column of this chart.
