Removing character strings within a hashtable

Hello all PowerCLI'ers out there.  Here's what I hope will be an easy one for you guys.

I have built a hashtable named $hostInfo that contains information about our VMHosts.  The information when displayed in a table format shows Name, UsedMemoryGB, TotalMemoryGB, FreeMemoryPct.

The 'Format-Table' output looks like this:

Name                                                               UsedMemoryGB             TotalMemoryGB                        FreeMemoryPct
---------                                                               -----------------------             ------------------------                        -----------------------
us1esx0201.company.local                              89.07421875                  95.989414215087890625           92.79587700202785441462201182
us1esx0209.company.local                              84.8193359375              95.989414215087890625            88.36321862267168020854706439

Here is the code snippet that generates this hashtable:

$hostInfo = Get-VMHost |

    Select Name, `

    @{N="UsedMemoryGB";E={$_.MemoryUsageGB}}, `

    @{N="TotalMemoryGB";E={$_.MemoryTotalGB}}, `

    @{N="FreeMemoryPct";E={(($_.MemoryUsageGB / $_.MemoryTotalGB) * 100)}} |

    Sort-Object -Descending -Property "FreeMemoryPct" | Select -First 10

Here is my challenge...I wish to remove the ".company.local" from all the entries in the 'Name' column and only leave the actual hostname.  How would I go about iterating through the 'Name' key and removing only this part of the string?

Any help is appreciated as always!
