If the rumored San Diego-Tampa Bay trade goes down, it’ll be a big change for Hunter Renfroe, the ex-Mississippi State standout who is a key piece in the deal. The power-hitting outfielder would go to the Rays along with a top prospect for outfielder Tommy Pham and a prospect. For Renfroe, that’d be a change not only of time zones and leagues but also of expectations. Tampa Bay, in the dog-eat-dog American League East, won 96 games and a wild card playoff berth in 2019 and won 90 games in 2018. The Padres finished 70-92, last in the National League West, in 2019. The Padres have finished fourth, fifth and fifth in Renfroe’s three full seasons with the club. They’ve already made a couple of big trades this off-season. Renfroe, a corner outfielder with a big arm, hit 33 homers last season but batted just .216; he was a Gold Glove finalist in left field. Pham, the Rays’ left fielder, hit .273 (.369 on-base percentage) with 21 homers and batted .360 in the postseason. Tampa Bay’s right fielder last year was rookie Austin Meadows.
