Matt Shaw is the Cubs’ best prospect since Kris Bryant and will get a “long look” at third base during spring training to see if he can do what his predecessor couldn’t: break camp with the big club. To be fair, Bryant more than earned the job in 2015 and was held at Triple-A just long enough for the Cubs to get an extra year of service time. And just because a lot of folks still like to defend the Cubs on that one, it’s the very definition of service-time manipulation.
