Trade Cesar Hernandez
At this point, it seems extremely likely that Cesar Hernandez will be traded at the Winter Meetings. Philadelphia has reportedly already received offers from other teams for the second baseman, and they should definitely be listening.
Hernandez should net the Phillies a solid prospect in return. He was worth 4.3 fWAR in 2016 and 3.3 this year after missing a month due to injury. His batting average and on-base percentage were essentially the same the last two seasons (.294 and .371 in 2016, .294 and .373 in 2017). Hernandez also showed slightly more power with nine home runs and a .127 isolated slugging percentage this year.
Trading Hernandez would also help the team out as it clears up the budding logjam in the middle infield. Klentak has said he would go into 2018 with that logjam still in place, but he probably said that to not give away any leverage in a trade. I’m sure, if given the option, he would try to clear up the logjam, and moving Hernandez gets the most return among any other player.
