redis sorted set highest score

Is any simple method to get the highest score from Redis sorted set? I found this way, may be there is better ways to make this(in ruby):

all_scores = Redis.zrange('foo', 0, -1, with_scores: true) # => [["item 1", 2.5], ["item 2", 3.4]]
all_scores.flatten.last # => 3.4

It seems not the best way.

you can use ZREVRANGE command. 

ZREVRANGE foo 0 0 withscores

This will give you the highest score and it's value.
