With the trade to the Indians pending on Saturday, Jimenez made his regularly scheduled start for the Rockies and tossed 45 pitches in a four-run first inning before being removed and notified of the deal.
Jimenez offered to start the Tribe's series finale with the Red Sox on Thursday, but Acta thought it would be better to let Justin Masterson -- who has a 1.25 ERA over 21 2/3 career innings against Boston -- finish the series as scheduled. Jimenez will make his first start in an Indians uniform on Friday against the Rangers, an 8:05 p.m. ET game in Arlington.
"Obviously, it was a roller coaster for him over the last 10 days," Acta said. "That's the only team he's ever known. He joined them when he was 16 years old. Going through this type of situation for the first time in his career wasn't easy for him. He's relieved that it's over."
Jimenez will join the club in Boston on Wednesday. Friday's start, coming on five days' rest, will be the 27-year-old's first against the Rangers, one of just six teams he has yet to face, including the Rockies.
After enjoying his break-out season with Colorado a year ago, Jimenez is 6-9 with a 4.46 ERA this season, with 118 strikeouts in 123 innings. But his ERA away from Coors Field is significantly lower than at home, with a 3.38 ERA on the road compared to 5.55 at Coors.
To make room for Jimenez on the 40-man roster, the Indians activated Mitch Talbot from the 15-day disabled list and designated him for assignment. Acta said he has a plan in place to make room for Jimenez on the 25-man roster, but he hasn't announced it yet.
