Alonso delivered a high-throw to first base on Thursday, causing Senga to jump for the ball. In the play, Senga strained his hamstring and is headed to the injured list. After the game, Alonso addressed the play and said he feels awful.

According to manager Carlos Mendoza, Senga said he felt his hamstring grab one stride before he made a leaping grab of Alonso’s high throw.

Kodai Senga was placed on the 15-day injured list with a right hamstring strain Friday, a day after covering first base on a grounder to Pete Alonso in the sixth inning. Senga had to reach up while stepping on the base because of a high throw and immediately grabbed the back of his leg and collapsed to the floor.
