Mariners 5, Royals 1
Manager Mike Hargrove isn't letting on -- yet -- whether that will happen.
Baek overpowered Kansas City, carrying a no-hit bid into the sixth, and Willie Bloomquist's second hit of the season was the difference in Seattle's 5-1 win over the Royals on Sunday.
Seattle won for the fifth time in its last six, and Baek's performance perpetuated the debate about Jeff Weaver's future in the Mariners' rotation.
Weaver, who is winless in four starts with an 18.26 ERA, was pulled after just one-third of an inning Saturday night, giving up six runs and seven hits. Hargrove knew the question was coming after Baek's performance Sunday, but wasn't ready to make a pronouncement about his future rotation.
"That will work its way out. That's a legitimate question, but again it's not fair to anybody if I comment on that right now," Hargrove said.
Baek pitched well in August and September last year, going 4-1 in six starts. He started this season in Triple-A, but was called up on April 23 when Hernandez went to the disabled list with a muscle strain in his right forearm. Baek threw 4 1-3 innings in his first start against Texas.
He dominated the Royals for six innings, and needed to as Seattle managed just four hits off Kansas City starter Brian Bannister (0-1). Mark Grudzielanek got the Royals' first hit on a line drive single to center with two outs in the sixth.
When Baek tired in the seventh, rookie Brandon Morrow (2-0) entered and got a pair of strikeouts with runners on second and third. He then pitched a perfect eighth.
Morrow got the victory after Bloomquist took advantage of a second opportunity. Bloomquist fouled off a 3-2 pitch from Bannister and the ball got stuck behind catcher John Buck's chest protector. Buck tried to jog off the field, claiming the inning was over. Home plate umpire Chris Guccione immediately called it a foul ball, but then listened as Buck and Royals manager Buddy Bell argued to reverse the decision.
Guccione conferred with the rest of the crew and his initial ruling stood. Rule 6.05b states the batter is not out if the ball lodges in the catcher's equipment or clothing unless it hits his hand or glove first.
"First of all, they have to simplify the rule," Bell said. "That play happens too fast for the home plate umpire; it happens too fast for the second base umpire. If he fouls off the ball and it doesn't hit the ground, it should be a strikeout, plain and simple."
"He did make the right call," Bloomquist said. "I was fortunate to get a second chance right there and I was hoping he would throw me another strike to get another chance at it."
Richie Sexson added an RBI single in the eighth, his first single of the season in his 69th at-bat. All nine of his previous hits in April were doubles or home runs.
DeJesus and Alex Gordon were the only Royals' to reach base before Grudzielanek, both on walks.
Emil Brown pinch-ran for Sweeney and scored on Reggie Sanders' broken-bat flare that dropped between shortstop Betancourt, second baseman Bloomquist and Suzuki in center field. Gordon then doubled off the wall behind Suzuki, advancing Sanders to third to end Baek's day. Baek allowed four hits and struck out six.
"I felt much better with (catcher Jamie) Burke. I just followed him. He made great calls," Baek said.
Morrow took over and struck out Tony Pena Jr. and Buck, who was pinch-hitting, to keep the game tied at 1-1.
Bannister was nearly Baek's equal. Burke lined an RBI double into the right field corner in the second, but Bannister retired the next 14 batters until Sexson walked to start the seventh.
"It's always tough when the other guy is throwing a no-hitter," Bannister said.
Sexson was forced at second on Guillen's slow grounder, but Betancourt then lined a shot into left field and Guillen advanced to third. Betancourt aggressively made it to second, sliding around Grudzielanek's initial tag attempt, then dove back to the bag before Grudzielanek could tag Betancourt's hand.
With the infield in, Burke popped up on the first pitch before Bloomquist's hit.
