With Jaso on seven-day DL, A's recall Vogt
By Jeff Kirshman / MLB.com
OAKLAND -- The A's recalled catcher Stephen Vogt from Triple-A Sacramento on Thursday to replace John Jaso, who was placed on the seven-day disabled list designated for players with concussions.
Jaso exited Wednesday's series finale against the Astros in the eighth inning with a headache after he was hit in the mask by a foul tip for the third time in four games. He had reached base safely in each of his past 27 starts at catcher prior to the incident.
"Nowadays, there's more evidence and more scrutiny put upon those types of things," A's manager Bob Melvin said. "In the past, you kind of just played through these things and I think it's shown with some injuries, head injuries in the past, that you do need to be more careful with it."
Melvin said he anticipates the seven days will be enough for Jaso to recuperate. He must spend a minimum of seven days on the DL, and he will be transferred to the 15-day DL if he isn't reinstated after 14 days.
"I think that's why they did it, made it seven days, because they got together with whoever the proper people are to diagnose these things," Melvin said of the rule established specifically for concussions. "But yeah, I would think [Jaso would be back]."
Vogt made a good showing with his first appearance with the A's in early July. He went 2-for-13 with a home run for his first Major League hit in his first stint with the club. The A's won all four games he started at catcher, and Melvin credited his ability to manage Oakland's starters despite a limited rapport with the staff.
Vogt has batted .323 with four home runs and 15 RBIs in 16 games with Sacramento since he was optioned back down, and he posted a .324 average with 13 home runs and 58 RBIs in 74 games with the River Cats this season.
Rosales aims to boost offensive production
OAKLAND -- Adam Rosales was nestled in for a mid-morning nap on Tuesday when A's assistant general manager David Forrest called him with news that he had been recalled from Triple-A Sacramento.
"It was a great wake-up call to know that I'm coming back to help the team out," said Rosales, who joined the team in Houston on Wednesday.
The middle infielder's designation to Triple-A on July 8 served as a wake-up call in its own right that his offensive production will need to improve if he's going to prolong his stay in the Majors.
"Whenever anything like that happens, at least in my experience, it's always been a wake-up call to me," Rosales said. "I understand it's to get me right. And in order to play here, you got to be able to hit.
"It's the Major Leagues. You got to expect to hit and expect to perform every day, and I understand that and that's what the team needs from me, and I plan on doing it this time."
Rosales was batting .200 with four home runs and eight RBIs in 48 games prior to his demotion, and he batted .240 with six RBIs in six games with the River Cats.
Known more for his proficiency on the defensive end, Rosales said his confidence had dwindled at the plate in the weeks leading up to his stint in the Minor Leagues, adding that he's focusing on improving his mentality with his at-bats.
Oakland has committed seven errors in five games since the All-Star break, including six in two games against the Astros. Three of those were charged to Grant Green, who was optioned following Tuesday's loss in Houston.
Vinnie Catricala was designated to Double-A Midland to clear a spot for Rosales on the 40-man roster.
"I think if I continue to play solid defense, that's the No. 1 role for me, but I need to be able to help the team out on offense better than I was before," Rosales said.
A's look to clean up after rough defensive series
OAKLAND -- Wednesday's error-free game in the A's 4-3 victory over the Astros was a welcome return to form for a team that had committed a season-high three in each of the two games prior.
The back-to-back defensive debacles marked the first time the A's have posted consecutive games of three or more errors since Sept. 23-24, 2009; the three unearned runs allowed in their last three games matched the amount allowed over the 35 previous contests.
Oakland still pulled out the 2-1 series win over the Astros despite its lackadaisical defensive display. A's manager Bob Melvin credited his team's ability to continue notching victories in spite of its shoddy play.
"You know you're going to go through stretches where you don't play well," Melvin said. "Sometimes it's going to be the defense, sometimes it's going to be the hitting and sometimes it's going to be the pitching. When you're going through a period where you don't feel like you're playing well in a certain facet, it bothers you some, but you just have to tighten it up and play better because we have the ability to."
The A's own the 16th-best fielding percentage in baseball at .984, with 60 errors in 3,666 chances over 101 games.
"When you're not playing well, you're trying to stay away from losing too many series in a row, too many games in a row, and if you can scratch out a couple of wins and win a series like we did in Houston even though we didn't play great, I think that's a great sign," Melvin said.
Attention won't stray from field as Deadline approaches
OAKLAND -- The A's and general manager Billy Beane are notorious for their willingness to pull the trigger on deals at the Trade Deadline, but manager Bob Melvin insists it won't serve as a distraction for his team as the July 31 Deadline looms less than a week away.
"I don't think it's much of a distraction for these guys, to be honest," Melvin said. "Whether something's done or not, we feel like we have a good team. It would be one thing if everybody was looking at a glaring weakness we need to address. You're just trying to incrementally upgrade your team, and if there's something out there to be done then you do it."
White Sox starter Jake Peavy has been rumored to be on the A's radar, according to CBS Sports' Jon Heyman. Oakland may also look to upgrade a middle infield that has featured a platoon of Adam Rosales and Eric Sogard -- serviceable but not stellar solutions at the position, especially considering Oakland's sporadic hitting this season.
Nonetheless, the A's (59-42) hold a 3 1/2 lead over the Rangers in the American League West and own the best mark in the Majors since July 1 of last year.
"I think based on where we are, we feel good about our team," Melvin said. "We don't look too far ahead. I think you have long-term goals and short-term goals. Our long-term goal is, yeah, we think we can go back to the postseason again, but then we narrow it back down to today and doing everything we can to win today."
