I was watching one of the Dodgers games last week and was watching White pitch. He didn't look too bad and I did like his stuff.
Definitely think he'll make a solid No. 4 or 5 starter and has team control which is a nice thing. Again, he's nothing flashy but in 15 games, 10 starts, has pitched 56 innings with a 3.70 ERA and 4.23 xFIP with a 0.7 WAR. Syndergaard on the other hand in 15 starts has a 3.83 ERA, 4.27 xFIP and a 1.2 WAR. So given contract, stats and even team control, White is a much valuable asset IMO.
At least if a Jays starter goes down on the IL, White could hold his own in the rotation and give you a chance every 5th day.
