Rockies acquire pair of prospects from White Sox for Doyle

DENVER -- The Rockies acquired right-handed pitcher Mason Adams and 16-year-old Venezuelan infield prospect Carlos Vielma from the White Sox for center fielder Brenton Doyle on Monday, with the Trade Deadline approaching at 4 p.m. MT.

The move – which was not immediately announced by officials because of required medical reviews – was the beginning of reshaping the Rockies’ outfield, as well as adding to their pitching.

TRADE DETAILS
Rockies receive: RHP Mason Adams (COL's No. 19 prospect), INF Carlos Vielma
White Sox receive: CF Brenton Doyle

Rookie Cole Carrigg, called up in early June with Doyle hampered by injuries, has slashed .305/.389/.525 in 44 games.

Adams, 26, was a White Sox 13th-round Draft pick in 2022 out of Jacksonville University, but used an outstanding curveball and a slider to put himself on the Major League map by Spring Training 2025. However, he sustained a right elbow injury that required Tommy John surgery.

In his return to the mound this season, Adams is 3-4 with a 3.86 ERA with 48 strikeouts and 19 walks in 49 innings pitched across three levels. At the time of the trade, Adams was pitching at Triple-A Charlotte and was 3-3 with a 4.25 ERA in 36 innings over nine games (seven starts), with 36 strikeouts and 17 walks. He was ranked Chicago's No. 8 prospect at the time of the deal.

Vielma received a $1.5 million bonus as an international signee in January, and batted .337 with one home run and 21 RBIs while in 34 games playing mostly third base for the White Sox’s Rookie-level Dominican Summer League club.

Doyle, 28, who won Gold Glove Awards his first two Major League seasons (2023, 2024) batted .214 with one home run and five RBIs for the Rockies over 45 games that were marred by a slow start, then injuries – a left oblique contusion sustained in May, followed by a left groin strain he sustained during his injury rehab assignment at Triple-A Albuquerque.

Doyle, who avoided arbitration this year with a one-year, $3.1 million contract and is not a free agent until 2030, found his swing during his final rehab stint, and in two games with the Rockies after his return, he went 2-for-6 with a walk, a double and an RBI.

Multiple teams reached out to the Rockies at last year’s Trade Deadline, but could not pry away Doyle. This year, Doyle drew interest in part because many teams were seeking right-handed hitters.
