The New York Mets are expected to place first baseman Pete Alonso on the injured list Friday, multiple media outlets reported.

MLB.com reported versatile infielder Luis Guillorme will leave his Triple-A Syracuse teammates and travel to Pittsburgh to meet the Mets ahead of the struggling team's opener of a three-game series against the Pirates. New York has lost a season-high six in a row to fall 8 1/2 games behind the first-place Atlanta Braves in the National League East.

Alonso injured his wrist after being hit by a fastball from Atlanta Braves right-hander Charlie Morton on Wednesday.

X-rays were negative for Alonso, who also had a CT scan Thursday morning before leaving the team and returning to New York for an MRI and further testing.

Alonso, 28, has a majors-best 22 home runs and NL-leading 49 RBIs through 62 games while batting .231. The two-time All-Star has 168 homers and 429 RBIs through 592 career games dating to 2019, when he was NL Rookie of the Year.

Guillorme, 28, is batting .233 with three RBIs and eight runs in 27 games this season with the Mets. He is a career .264 hitter with four homers and 42 RBIs in 307 games with New York.
