Scott, 33, is a well-traveled righty who made 24 appearances between the Astros and Diamondbacks last year. He struggled to a 7.90 earned run average over 27 1/3 innings. The South Africa-born pitcher is only a year removed from firing 68 2/3 frames of 2.23 ERA ball with Houston. He carries a 5.51 mark with a 21.2% strikeout percentage and 12.2% walk rate over parts of five MLB campaigns.
The 6'0″ righty made 15 starts for the Samsung Lions after signing in June. Garabito pitched well, turning in a 2.64 earned run average with a 26% strikeout rate. That makes it a bit surprising that the sides didn't work out an agreement for the 2026 season. Garabito instead will try to pitch his way back to the big leagues in Spring Training.
Amaya joins the system after spending the 2025 season with the White Sox. He appeared in a career-high 36 games but only batted .106 with one extra-base hit (a double) in 73 trips to the plate. The 27-year-old spent the rest of the season with Triple-A Charlotte. He hit .250/.352/.420 with nine homers across 219 plate appearances. He posted decent batted ball metrics but struck out in 29% of his trips to the dish.
Rooney elected minor league free agency after being outrighted by the Astros at the beginning of the offseason. The 28-year-old had a brief stint with Houston, who acquired him from the Marlins in a small trade in August. The Astros called him up for his big league debut three weeks later. Rooney struck out two of six batters faced while giving up a solo home run to Luis Vázquez in his only appearance.
