They should do both this trade-deadline. Buy & Sell.
Have to sell Burnes just because of his being the number 1 player available and the bidding war that would ensue. They might even get a player that could help them in August/September like Ezekiel Duran from Texas, who i guess would likely be one of the bidders with deGrom having TJ.
The rest they could hold, unless the LAD make a big offer for Adames, who will start to regress to the mean over the next 7 weeks.
They have enough pitching with Miley, Woodruff, Peralta, Rea, Teheran, Houser and Gasser, who’s about ready for call up. Offense needs buttressed, and they have Urias they could trade for a less controlled better hitter and mid-level prospects they can also trade to improve the offense and possibly add a bullpen arm.
