Toronto will be waiting for its opponents for the ALDS after the conclusion of the Wild Card series.While Shane Bieber has performed admirably since his move to the Blue Jays at the trade deadline, pitching 40.1 innings with a 3.57 ERA and 37 strikeouts in seven starts, his performance in the postseason will likely decide his MLB future.The former Cy Young winner is in the last year of his contract and the 30-year-old could command a lucrative contract in the offseason after a strong showing for the Blue Jays in October. If Bieber can re-establish himself as one of the best starting pitchers in the league, he could be in for a big payday in the offseason.
