The 21-year-old academy graduate's loan with the Saddlers was due to run until the end of the season but instead he was thrust into the thick of Everton's troubled Premier League season after just five games in League One.
But he didn't disappoint anyone on his debut for Roberto Martinez's side, with a display full of promise.
Not that it would have been any surprise to Walsall fans where he has been earning solid reviews for his performances.
And he earned another gushing assessment of his qualities on his top flight debut from none other than a former Liverpool hero in the shape of Danny Murphy.
'He can be very pleased with himself'
The former Red turned pundit eulogised about the defender in on BBC's Match of the Day after an accomplished performance.
"He did (really well), he got recalled recently from his loan spell because of the injury to Phil Jagielka and the sending off of (Funes) Mori," Murphy told MOTD.
"He actually had a bit of bad luck early on in the game, it could have knocked his confidence, he got a little nudge in the back - a little bit out of position he was - another day that would have been given as a foul and Bournemouth ended up getting an equaliser from it.
"But he didn't let it get him down at all, he actually grew stronger because of it.
"He was aggressive, he was quick, he put his body on the line many times and he really responded well to the challenge.
"He was up against some quick, strong players today, Bournemouth have got some decent forwards and he showed all the attributes you want in a young player: hunger, desire, the fans took to him like they always do when you give a young player an opportunity.
"He showed his athleticism a few times as well which of course in today's game you need and he tried to play as well which of course Roberto Martinez likes from his players as we know, if maybe too much at times.
"He can be very pleased with himself at a difficult time to play at Goodison he showed himself to be a very capable young man and deserves credit for that."
Pennington a silver lining to dark clouds
Pennington had played for the Blues in the Capital One Cup win at Barnsley and the FA Cup victory over Dagenham and Redbridge earlier this season.
But this was a step up in class with the likes of jet-heeled Callum Wilson and Jonathan King offering Pennington a much more difficult task.
As Murphy points out, though, Pennington handled it all in his stride and in these turbulent times for the Goodison Park outfit offers something of a silver lining to the dark clouds gathering over the Blue half of Merseyside.
