Try this:

players_avg = <<PLAYERS
Barry Bonds, .293
Mike Gallego, .263
Ichiro Suzuki, .396
Tony Gwynn, .403
Alex Rodriguez, .310
PLAYERS

lines =  players_avg.split("\n")
player_data = []

#chop lines into pieces
for line in lines
  data = line.split(',')
  names = data[0].split()
  avg = data[1]
  player_data << [names[0], names[1], avg]
end

#sort array by 2nd element, i.e. last name:
results = player_data.sort() do |arr1, arr2|
  arr1[1]<=>arr2[1]
end

#output data:
results.each() do |arr|
  puts "%s, %s %s" % [arr[1], arr[0], arr[2]]
end

--output:--
Bonds, Barry  .293
Gallego, Mike  .263
Gwynn, Tony  .403
Rodriguez, Alex  .310
Suzuki, Ichiro  .396
