ESPN MLB Insider Keith Law has some advice for Mets outfielder Tim Tebow: Keep your day job.

While speaking on a conference call to discuss his 2017 rankings of the top 100 prospects and MLB farm systems Monday, Law was asked about Tebow. He didn't hold back.

"I think Tim Tebow should stick to announcing and never play baseball again," Law said. "He was the worst player I've ever seen in the 10 years I've been going to the Arizona Fall League."

Tebow, who signed a minor league contract with the Mets that included a $100,000 signing bonus in September, failed to impress in his baseball debut. The former quarterback played for the first time since high school in the Instructional League before being sent to the Arizona Fall League, a league typically reserved for high-profile prospects.

While there's no question that Tebow is a high-profile player, he never quite earned the prospect label, hitting .194 with 20 strikeouts in 62 at-bats in 19 games as an outfielder and designated hitter.

It's not the first time that Law has ripped Tebow. The scouting writer said Tebow didn't belong back in October.

"He might be better suited to playing in an Arizona high school league," Law wrote. "His presence here is a farce, and he looks like an imposter pretending to have talent he does not possess."

One scout echoed a similar sentiment to NJ.com's Randy Miller during Fall League play.

"He was a little out of place and overmatched at this setting. He didn't look very athletic out there. He wasn't able to hit a good fastball. That's expected when you haven't played baseball in a long time. I think he's got a lot, a lot of work to do."
