SAN DIEGO — The Chicago Cubs have optioned top prospect Matt Shaw to Triple-A Iowa after a disappointing start to the rookie third baseman’s career.

Shaw, the No. 13 pick in the 2023 amateur draft, is just 10 for 58 with one homer and three RBIs. He has 18 strikeouts in 68 plate appearances. The Cubs also placed right-hander Eli Morgan on the 15-day injured list because of an elbow impingement. Infielder Vidal Bruján was reinstated from the 10-day IL, and right-hander Nate Pearson was optioned to Iowa.

Left-hander Luke Little and right-hander Daniel Palencia were recalled from Triple-A before the Cubs’ game at San Diego.

A call for help

MILWAUKEE — The Milwaukee Brewers have recalled Logan Henderson from Triple-A Nashville to help a pitching staff dealing with multiple injuries.

The Brewers made room for Henderson by sending right-hander Elvin Rodriguez to Nashville. Rodriguez had an 0-2 record and a 7.53 ERA in four appearances.

Henderson is expected to work out of the bullpen for now, though he has started in all 47 of his career minor league appearances.

Moving pieces

CINCINNATI — The surging Cincinnati Reds had all of their key players for the first time this season after making a series of roster moves before Tuesday night’s game against Seattle.

The Reds activated right-hander Alexis Diaz, infielder Matt McLain and outfielder Austin Hays. Cincinnati goes into the three-game series with Seattle after wins in five of its last six.
