If I'm the GM and assume a modest amount of money is left then my last big strike is going to be for a starting pitcher. Masahiro Tanaka at his 1/15 asking price is very appealing, but there are others like Paxton and Odorizzi.
I like the bullpen with the recent additions and wouldn't spend on a guy like Hand if it prevented upgrades in other areas. Darren O'Day stands out as a ground ball specialist that could fill the Anthony Bass role for cheap, but there are many options. He's just an example.
Regarding third base, I'd be tempted to trade for a guy like Eugenio Suarez, but tying ourselves into a long term deal for a mediocre defender doesn't really align with the goals of the FO. Instead, I'd look to add a player on a 1 year deal and reevaluate during next year's FA class. That could be Semien, Gregorius, Turner, Simmons, Hernandez, etc. It's a game of musical chairs and someone will settle for a 1 year deal. I'm not against Bryant either if the money is there and it doesn't take a top 5 prospect.
