On Tuesday, the subject was Chris Martin, who lasted one pitch in the ninth inning of a 4-1 game against Colorado, then walked off the mound and seemed to say “it popped,” on his way back to the dugout with athletic trainer Matt Lucero. It came a day after Luke Jackson was hit by a line drive on the hand and wrist on the first pitch he threw.

Corey Seager has been placed on the 10-day injured list again by the Texas Rangers. The two-time World Series MVP shortstop had already missed four of their previous five games because of right hamstring soreness before the move Tuesday.
