Fulfilling a promise made several weeks ago, the Arizona Diamondbacks promoted pitcher Trevor Cahill from Triple-A Reno on Monday, reports Nick Piecoro of The Arizona Republic. He will start for the D-Backs on Friday as they host the Chicago Cubs at Chase Field.
The news continues a busy season for Cahill, who began his season in Arizona’s starting rotation before being demoted to the bullpen. From there, the team decided to stretch him back out with a trip to the minor leagues, all with the promise of an eventual return to the big league rotation this season.
On Monday, the Diamondbacks followed through on that promise, even though Cahill wasn’t exactly great in the minors. Over seven appearances — six with Triple-A Reno and one with Single-A Visalia — he’s posted a 4.45 ERA with 31 strikeouts and 20 walks.
Piecoro says the team hoped Cahill would hammer out some of his command issues with the minor league stint, and “on that front, the results aren’t encouraging.” Indeed, 5.9 walks per nine innings isn’t exactly a low figure, and is actually more than the 5.4 walks per nine innings he allowed with Arizona earlier this year.
Over 41.1 big league innings in 2014, Cahill has a 5.66 ERA with 44 strikeouts and 25 walks.
In order to make room on the 25-man roster for Cahill, the Diamondbacks optioned right-handed pitcher Mike Bolsinger to Reno. Bolsinger has struggled in his first MLB season, posting a 1-6 win-loss record and 5.50 ERA over 10 appearances (nine starts). His peripherals are much better, including 48 strikeouts and 17 walks in 52.1 innings.
