Kemp, 28, began the 2019 season with the Astros but was sent to the Cubs at the trade deadline for catcher Martín Maldonado. Between both teams, Kemp hit .212/.291/.380 over 279 plate appearances. While he isn’t much in the way of offense, he’s a good base runner and a good defender with lots of versatility.
Rivas, 23, was selected by the A’s in the fourth round of the 2018 draft. He spent most of his 2019 season with High-A Stockton before earning a promotion to Triple-A Las Vegas just before the end of the minor league season. With Stockton, Rivas hit .283/.383/.408 over 509 trips to the plate.
