Stumped by -Replace with RegEx

I have some files with lines of text that will include a date int eh format of Mar 1, 2015. I need to replace any dates with the format of 3/1/2015. I can correctly identify the date with a regular expression, just not sure how I can use a -Replace to change the format. Can anyone assist?

CODE -->

$WordDate = "(?<month>[\dA-Za-z]+) (?<day>\d{1,2}), (?<year>\d{2,4})"
$Line = "4I0139L4               Mar 1, 2015 12:18:58 AM               1 Years"

I am able to replace with the current date, but I need to identify the date that is already in the line that was matched with the regular expression. Any help would be appreciated.

RE: Stumped by -Replace with RegEx

Well, I finally got it. There may be a more efficient way to do this and I would be grateful for any suggestions. This does all I needed though. Removed all time strings and replaces dates listed as Month Day, Year as MM/dd/yyyy format then writes the data back to the file.

CODE -->

$FTPContent = (Get-Content C:\Temp\OpsCenter_4I-FTP_23_02_2015_07_00_12_998_AM_12.TSV) 
$WordDate = "(?<month>[\dA-Za-z]+) (?<day>\d{1,2}), (?<year>\d{2,4})"
$TimeRegex = "(1[012]|0?\d):[0-5]?\d(:[0-5]?\d)?\s+[AaPp][Mm]?"
Foreach ($Line in $FTPContent)
    $Date = $Line | % {$_ -match $WordDate > $null; $matches[0]}
    $a = Get-Date($Date)
    $a.ToString('MM-dd-yyyy') > $null
    $NewLine = $Line -replace $WordDate, $a
    $NewLine2 = $NewLine -Replace "00:00:00",""
    $NewLine3 = $NewLine2 -Replace $TimeRegex,""
    $Report = $Report + $NewLine3 + "`r`n"
Set-Content C:\Temp\OpsCenter_4I-FTP_23_02_2015_07_00_12_998_AM_12.TSV $Report 

I hope that helps.
