Reddick slotted in two-hole with Jaso struggling

KANSAS CITY -- Never one to get too comfortable in any lineup position, Josh Reddick was on the move again Monday, batting second for the first time this season and just the seventh time in his career.

The shakeup is not only a reflection of Reddick's recent production but of John Jaso's lack of success at the plate.

Jaso has been a fixture in the No. 2 spot against right-handers, splitting time there with Jed Lowrie for much of the season. But he was batting eighth against Royals righty Yordano Ventura on Monday amid a 1-for-25 stretch.

He hit .323 with a .366 on-base percentage in the month of July.

"John's just a little off right now, so we're not completely back offensively to where we were before, but I think we're swinging better," said manager Bob Melvin, "and sometimes you just try to change the scenery a little bit and get someone who's swinging a hotter bat a little farther up in the lineup."

Reddick went 12-for-36 during the club's 10-game homestand, and he's batting .328 overall since coming back from the disabled list July 22, bumping his season average to .256.

"He's swinging the bat pretty well," said Melvin. "He's been using the whole field, driving some balls. I had several options today for the lineup, just went with this one."

Reddick has now made starts at six batting positions this year and eight in his career, not once hitting cleanup.

He went 0-for-4 in Monday night's series opener, a 3-2 loss to the Royals. Jaso went 1-for-3 and scored on Brandon Moss' game-tying single in the third inning.

Vogt's value to A's goes beyond catching

KANSAS CITY -- A lingering bone bruise in his right foot has prevented the A's Stephen Vogt from catching duties for more than a month, and it's unlikely he returns to them by season's end. That hasn't stopped him from contributing in other ways.

Vogt, batting .319 on the year, made his 20th start at first base on Monday in Kansas City, and he says he's made enough progress at the position to the point where he feels like he could be there on an everyday basis.

"But I don't want to lose the ability to play everywhere," he said.

That's what makes him so valuable to this team, even when he can't catch.

"We have to find a way to get his bat in the lineup, and based on how he's swung the bat since he's been here, to be able to put him in different positions, it's great," said manager Bob Melvin. "It's not something, when we first brought him over I would've expected, but then you look back and see some of the positions he has played in the past, he's fit right in."

Vogt has been batting the bone bruise since at least May, and it worsened in June in Miami, where he finally revealed to the coaching staff the pain it causes when catching because of the particular positioning of his feet. He still very much feels it when pushing off, whether on the bases or in the field when going after a foul ball, but, "It is what it is," he said.

It's the type of injury that won't go away without rest, and that won't come until the offseason.

"I'll just continue getting the treatment and avoiding things that will make it worse, like catching," he said. "I'd like to think that I can catch again this year if it's feeling better, because the pain's becoming more tolerable, but at this point, wherever I can help the team the most is where I want to be. Whether that's at first, or DHing or outfielder, that's what I want to do. Obviously the inner catcher in me wants to catch, but we have two pretty good catchers."

Worth noting

• Right-hander Ryan Cook pitched a clean eighth inning on Monday to extend his scoreless streak to 19 innings, which is the longest active streak in the Majors.

• Just in time to do more damage against his former A's team, outfielder Josh Willingham was traded to the Royals on Monday evening. Willingham is expected to DH for Kansas City, where the A's will be through Thursday.

He's a career .339 hitter with a 1.188 OPS and eight home runs in 18 games vs. Oakland.
