Pirates general manager Ben Cherington said Burrows was diagnosed with a forearm injury after exiting his start Saturday at Triple-A Indianapolis, Alex Stumpf of DKPittsburghSports.com reports.

EDGE Analysis

Cherington added that Burrows' elbow is stable, but the forearm issue still could be enough of a concern to keep the 23-year-old right-hander on the shelf for at least a couple turns through the rotation. Burrows worked 6.2 innings between his first two starts with Indianapolis, giving up two earned runs on four hits and two walks while striking out three.

Burrows was optioned Tuesday to Triple-A Indianapolis by the Pirates.

EDGE Analysis

Burrows has made two Grapefruit League appearances as of Tuesday, and he allowed two runs on four hits with one strikeout and no walks over three innings. The right-hander is considered one of the better arms in the Pittsburgh system and likely will make his MLB debut at some point in 2023.

Burrows is incorporating a slider into his pitch mix, Justice delos Santos of MLB.com reports.

EDGE Analysis

Burrows is among the top pitching prospects in the Pirates' organization, and he already possesses an above-average curveball. The slider is still a work in progress, though he has thrown the pitch eight times across three innings of work this spring. Burrows is extremely unlikely to break camp with the team, but he'll be among the top candidates to get the call when the Pirates need reinforcements in the rotation this season.
