Worth noting

• Designated hitter and first baseman Logan Morrison hit his second home run of his rehab assignment with Tacoma in the Rainiers' 13-4 win at El Paso on Tuesday as he returns from a strained right hamstring. Morrison is hitting .286 (12-for-42) in 11 games.

"He needs to play," McClendon said. "Get him in a groove and get him going. Ten at-bats is not going to do it. He's got to play. He's been out quite a while. And the fact is, he was hitting [.150] when he got hurt. Let him play and see what happens."

• Going into Wednesday's game, outfielder Michael Saunders had racked up 18 RBIs in 15 games since May 17, tied for the second most in the Majors in that span behind the 20 of Edwin Encarnacion. Ryan Howard and Nelson Cruz also had 18 RBIs in that stretch. Saunders has hit .340 with a .997 OPS in his last 15 games.

• Seattle's plus-28 run differential since the start of May is fourth in the Majors behind only Oakland (plus-59), Toronto (47) and San Francisco (36).

• Romero's pinch-hit homer on Tuesday was the first by a Mariners rookie since Jeff Clement on Sept. 26, 2007, and the 11th in franchise history. Other Seattle rookies with pinch-hit homers are Adam Jones (2007), Greg Dobbs ('04), Greg Pirkl ('94), Bill Haselman ('93), Griffey Jr. ('89), Bruce Fields ('88), Dave Hengel ('87), Reggie Walton ('80) and Joe Simpson ('79).
