#3 Joc Pederson
Joc Pederson is a player we said the Astros should consider trading for last season. He's not nearly as stout defensively as Gurriel, but also not as bad as Soler.
He's coming off of a season in which he posted a .764 OPS, but his 96th percentile hard-hit rate, 91st percentile average exit velocity, 90th percentile xwOBA, and 84th percentile xSLG show he actually was unlucky with his performance. He hit only .235, but his xBA was .263.
As a lefty, Pederson could take aim at the short porch down the line in right in Minute Maid. He could platoon in left and at DH with Yordan Alvarez in the same way Michael Brantley has previously. He walks more than Brantley, singles less, but provides more power. He'd be a good addition to the Astros lineup, and could likely be had for a three or four-year contract.
