Texas Rangers shortstop Corey Seager had an appendectomy on Thursday after experiencing abdominal pain during a game the previous night. Seager will be placed on the 10-day injured list and the Rangers will call up utility player Dylan Moore, who had just been signed to a minor league contract after being released by the AL West rival Seattle Mariners.

Chris Young, the team’s president of baseball operations, said Seager had surgery in Texas after the team had traveled to California for the start of a series against the Athletics on Friday night. Young said it was too early to know how much time the two-time World Series MVP will miss.

Center fielder Evan Carter (broken right wrist) is going to be transferred to the 60-day IL to make room for Moore on the 40-man roster.

The 33-year-old Moore, who was the longest-tenured Mariners player, was designated for assignment by Seattle on Saturday and placed on unconditional release waivers Sunday. Over seven seasons, he hit .205 with a .691 OPS, 61 home runs and 116 stolen bases in 671 games for the M’s. He also was the 2024 American League Gold Glove winner as a utility player.

Moore had a strong start this season, batting .289 with an .869 OPS with seven home runs and 13 RBIs through May 17. But his Mariners tenure ended after he went through a 3-for-74 slump (.045 average). Moore is hitting .193 with a .622 OPS, nine home runs and 12 stolen bases in 88 MLB games this year.

It was initially thought that Seager came out of Texas’ 20-3 win over the Los Angeles Angels on Wednesday night because of the lopsided score. The Rangers were up 11-1, and he had hit his 21st homer and scored three times before manager Bruce Bochy replaced Seager in the field in the top of the fifth inning.

“So did I,” Young said. “Boch was taking him out anyway, but the timing kind of lined up simultaneously.”

Young said Seager had experienced some pain before the game, but nothing that concerned the team or the shortstop. But that pain increased while playing, and he was diagnosed with appendicitis when he was evaluated after coming out of the game.
