Giants recall Kyle Harrison, designate Lou Trivino for assignment

The San Francisco Giants have recalled left-handed pitcher Kyle Harrison from Triple-A Sacramento, designating veteran reliever Lou Trivino for assignment in a move driven by performance rather than injury. Harrison, a top pitching prospect, impressed in Triple-A with a 3.46 ERA and 38 strikeouts over 26 innings, regaining his fastball velocity after dealing with illness and a shoulder injury earlier in the year. While Harrison initially lost the competition for the fifth rotation spot to Landen Roupp, he will join the Giants in a long relief role, potentially providing bullpen depth alongside fellow lefty Erik Miller. The Giants had previously used Trivino in low-leverage situations, but his 5.84 ERA over 12 1/3 innings and redundancy in the bullpen contributed to his departure. This roster adjustment reflects the team's desire to optimize pitching performance as they begin a six-game road trip. Harrison's strong recent outings and improved command could position him for a future rotation spot if current starters continue to struggle.
