After down seasons last year, Toronto Blue Jays starters Marcus Stroman and Aaron Sanchez were viewed by many as question marks entering 2019.

But almost through the month of April, both pitchers are off to blistering starts. Stroman leads the American League with a miniscule 1.43 earned-run average and Sanchez isn’t far behind him at 2.32. If both continue to get outs at their current pace, what could they fetch in the trade market if the Blue Jays decide to sell high?

According to ESPN’s Buster Olney, the Jays could shoot for a hefty return.

“The way that it’s shaping up this summer [versus last year] it’s the complete opposite where Stroman looks great and Sanchez look great,” Olney said Tuesday on TSN 1050’s First Up with Michael Landsberg.

“But some of the other guys who might be options on the trade market, like Madison Bumgarner, haven’t looked good so far and so you figure that if in fact the Blue Jays take [Stroman and Sanchez] out into the market they’re going to do really well and you would assume that the focus for the Blue Jays is going to be on adding pitching.”

Olney on Stroman's future with Blue Jays, Guerrero Jr. and more

ESPN MLB Insider Buster Olney joins First Up with Michael and guest host Dave Feschuk to discuss the future of Marcus Stroman with the Blue Jays, Vladdy Guerrero Jr's debut with the team and more.

As for the kind of return the Jays could get in a potential deal, Olney had this to say:

“But big picture, [this season] for the Blue Jays this is about promoting some of these great young prospects for the first time to get their first taste in the big leagues and then to see what they can get for Stroman and Sanchez, which as I say, should be really good as long as those guys continue to perform this way and stay healthy and it will fuel the rebuild. All you have to do is look and see what they gave up to the Mets for R.A. Dickey. And Noah Syndergaard, that’s the type of guy you could expect to get for Stroman and Aaron Sanchez.”

Both pitchers are under club control through the 2020 season. With Stroman turning 28 on Wednesday and Sanchez set to turn 27 this summer, will Toronto instead try to negotiate contract extensions as opposed to trading them?

“Look, we’ve seen all the extensions that teams have doled out this spring, but when you look at the timeline and the amount of service time that’s going to be required for guys like Vladimir Guerrero Jr. to settle in and some of their other prospects to settle in it makes a lot more sense for them to trade [Stroman]. That’s the expectation of other teams – that the Blue Jays will market Stroman and Aaron Sanchez this summer,” Olney said.
