The Rays and Cubs have agreed to an eight-player deal, in which the only major leaguer changing hands is Rays starter Matt Garza. His value immediately is raised by this deal because he goes from the murderer’s row that is the AL East, into the comparatively weak NL Central. He will be the Cubs No. 2 in their rotation. 15 wins, 1.20 WHIP and 3.50 ERA might be a low side of expectations.
