Mark McGwire looks like an entirely different person than he did in his playing days

The days of calling Mark McGwire 'Big Red' are over.

The former professional baseball player often referred to as 'Big Red' or 'Big Mac' is regarded as one of the greatest home-run hitters of all time. But he looks totally different than he did back in his red-headed playing days.

You remember him from way back then -- he was approaching the peak of his career, appearing in six consecutive All-Star games and shattering virtually every existing home run record at the time. He averaged a home run once every 10.61 at bats, the best at bats per home run ratio in baseball history.

While playing for the St. Louis Cardinals, McGwire broke the home run record with famous No. 62 in 1998 -- a moment baseball fans could never forget.

But the success was hindered by news that would follow years down the road. McGwire last made big headlines in 2010 for admitting to using steroids "off and on" for nearly a decade of his career, including that time he beat the coveted home run record.

Ever since then, he's maintained a fairly low profile.

But now, you wouldn't even recognize him if you saw him walking around in public. After a few years of various coaching gigs, McGwire is now a bench coach for the San Diego Padres.

Upon seeing the 52-year-old, one Twitter user was quick to point out how his appearance has drastically changed.

"Feels weird seeing Mark McGwire with gray hair. Always will think of him as Big Red."

Don't worry -- he may not look like 'Big Red' anymore, but he can still swing it.
