SEATTLE (AP) — Miles Mikolas allowed three hits in eight scoreless innings, J.P. Arencibia singled home the go-ahead run in the fourth and the Texas Rangers opened a three-game set against the Seattle Mariners with a 2-0 win on Monday night. Mikolas faced two batters over the minimum, erasing two of the three hits he allowed with double plays. The rookie stranded runners in scoring position in three innings before giving way to the bullpen after tossing 101 pitches. General manager Jon Daniels said the Rangers plan to activate LHP Derek Holland from the disabled list after his start Thursday for Triple-A Round Rock.
