The Guardians send starting pitcher Aaron Civale to the Rays for a first base prospect. The story buries the lede:

The move is a bit surprising from Cleveland’s standpoint since the Guardians are just one-half game out of first place in the AL Central and they have several pitchers, including ace Shane Bieber out with injuries.

Those injuries may be the reason. While the Guardians are just 1/2 game out in the division, they are six game out in the AL Wild Card race with five teams ahead of them for the third WC slot. If the starting pitching doesn’t get healthy soon, they may not have that much of a chance to win the division since the offense ranks low in runs scored. Civale pitched great since he returned from an injury in June, so Cleveland decided to sell high.

Kyle Manzardo is the prospect. He hit very well in the minors so far. In his first season at AAA he hit for power, but has not showed the on-base skills of his lower level stints. He is seasonal age 22, so he has plenty of time to adjust.
