Hours after reacquiring Kendrys Morales from the Minnesota Twins, the Seattle Mariners continued to tinker with their offense, bringing shortstop Chris Taylor and designated hitter Jesus Montero up from Triple-A Tacoma while placing infielder Willie Bloomquist on the 15-day disabled list.

Taylor, 23, will make his major league debut after dominating Pacific Coast League pitching this season, hitting .328 with five home runs, 37 RBIs and 63 runs scored in 75 games. The Mariners’ fifth-round pick out of the University of Virginia in 2012 was a Triple-A All-Star in July.

Montero, 24, will make his second appearance for the M’s this season after he hit .286 with a home run and two RBIs in five games with the club in June.

The formerly prized prospect has been on a tear since being optioned back to Tacoma on June 25, hitting .420 with seven home runs and 29 RBIs, but he may simply be keeping the DH spot warm until Morales reports to the team on Friday.

Both Taylor and Montero will be in the lineup Thursday night when the M’s kick off a four-game series with the American League East-leading Baltimore Orioles at Safeco Field, with Montero batting sixth and Taylor batting ninth.

Bloomquist, 36, suffered a right knee contusion in the eighth inning of Wednesday’s 3-2 loss to the New York Mets. The 13-year veteran was batting .278 in 47 appearances for the club this season after signing a two-year, $5.8 million deal to return to Seattle in December.

The Mariners had an open spot on the roster after optioning starter Taijuan Walker to Tacoma following Wednesday’s loss, a move they made official on Thursday.
