D'backs part with former Cy Young winner Keuchel

Former Cy Young Award winner Dallas Keuchel has been designated for assignment by the Arizona Diamondbacks after four ineffective outings.

The 34-year-old Keuchel hoped to resurrect his career with the D-backs after signing on June 7 but struggled with an 0-2 record and 9.64 ERA, giving up 20 earned runs over 18 2/3 innings. The left-hander was released by the Chicago White Sox in May after going 2-5 with a 7.88 ERA during the first two months of the year.

Keuchel was the 2015 AL Cy Young winner while with the Houston Astros.

GIANTS SIGN RELIEVER ROSENTHAL >> Right-handed reliever Trevor Rosenthal signed a $4.5 million, one-year contract with the San Francisco Giants. Rosenthal has a chance to pitch in the majors for the first time since 2020. He will be on the injured list with a hamstring strain initially.

The 32-year-old Rosenthal received an $11 million, oneyear contract from Oakland before the 2021 season but never pitched. He had surgery for Thoracic Outlet Syndrome in April that year and underwent surgery for a torn right hip labrum last July.

ALL-STAR GAME RATINGS DOWN AGAIN >> Major League Baseball’s Midsummer Classic remains the most-watched all-star game in the major professional sports, even though it drew record lows in viewership for the fifth time since 2015.

Tuesday night’s game from Los Angeles — which the American League won 3-2 — averaged 7.51 million viewers on Fox, according to Nielsen, a decline of 9.7% from last year’s contest in Colorado. The audience peaked at 8.24 million between 6:15 p.m. and 6:30 p.m. PDT.

The game was the mostwatched program on television Tuesday night and outdrew the three other major all-star games that were played in February.
