The Giants need to call up Kyle Harrison
It is hardly a secret that the Giants' biggest need at the moment is at starting pitcher. San Francisco has made things work in the wake of some injuries. With Ross Stripling getting activated from the IL and Alex Cobb looking like he is close to returning, reinforcements are coming to help out. However, that doesn't change the fact that the first thing the Giants need to do is promote Kyle Harrison to the big leagues.
Harrison is one of the best pitching prospects of all of baseball and while his last start was a rough one, he had given up a total of four earned runs in his last five starts before that while striking out a ton of batters. Harrison's stuff is simply tremendous from the left side especially with his weird arm slot and he is already stretched out to 80+ pitches. Kyle has been so good, in fact, that he was just selected to the 2023 Futures Game along with another Giants pitching prospect Carson Whisenhunt.
Whisenhunt's debut will probably have to wait until at least 2024, but Harrison's ability to miss bats is needed in the big leagues. There are certain to some speedbumps along the way, but getting Harrison access to big league coaching and resources should pay dividends for him. At the end of the day, he is probably better than any option the Giants could realistically find on the trade market to fill an obvious need.
Reinforcing the bullpen needs to be a priority for the Giants
Every team that is in contention is going to be looking for bullpen help and San Francisco is no exception. The Giants' bullpen is no exception because while they have been very good, they have also been used a lot and Luke Jackson hitting the injured list with a lower back strain is going to hurt their depth in the short term.
An emphasis on bringing in quality, fresh arms for the bullpen has some added importance with the team's shortcomings in the rotation and the chance they they will promote Harrison. In an ideal world, the injured guys coming back and Harrison would be able to cover a ton of innings, but San Francisco can't bet on that happening.
Fortunately, bullpen arms are plentiful at the trade deadline. The Giants should be looking to swing big here with guys like Aroldis Chapman, Scott Barlow, and Keynan Middleton being names that they will hopefully be looking at.
