OAKLAND -- A power outage forced a 16-minute delay in the fourth inning of Friday's contest between the A's and Tigers at the Oakland Coliseum.

The A's took the field for the top of the fourth before several banks of lights went out, causing them to return to the dugout.

Oakland and Detroit were locked in a 1-1 tie at the onset of the delay, which temporarily halted the Tigers' attempt at clinching the American League Central crown.

Allen playing through rookie travails

OAKLAND -- A's manager Bob Melvin isn't afraid to play rookies -- or any player, really -- through their struggles. In fact, he prefers to.

"You start taking a kid out and benching him, that can make you doubt yourself and so forth," Melvin said.

So when rookie first baseman Brandon Allen began struggling at the plate, Melvin kept running him out there. The offensive woes resulted in a 0-for-22 stretch, but Allen has since collected four hits in his last 12 at-bats.

"He's in a position here where he's our first baseman, and we want him out there each and every day knowing we have confidence in him," Melvin said. "We moved him down in the lineup a little bit to take some pressure off of him, but his at-bats are better. We're starting to see him come out of this thing."

Though Allen entered Friday's contest against the Tigers with 45 strikeouts in 117 at-bats with the A's, 14 of his 27 hits have been for extra bases, including nine doubles, two triples and three home runs.

Magnuson not close to baseball activity

OAKLAND -- Tucked away in a crowded A's clubhouse every day is Trystan Magnuson, his 6-foot-7 frame disguised because he's usually sitting, these days reading.

"I'm very bored," said a smiling Magnuson, who has been stationed on the disabled list with right shoulder tendinitis for nearly a month.

As a result, the reliever has already finished two books and started on two more -- "Blink" and "The Lone Survivor" -- thanks to recommendations by teammate and book fanatic Adam Rosales. Once those are read, he'll attempt to conquer "Moneyball."

"That definitely has to be next on my list," he said.

As for the baseball activity, there won't be any for a while, as Magnuson tried throwing last week only to be shut down again and given new anti-inflammatory medication.

"It didn't feel good at all, so we're going to take a little more time," Magnuson said. "It did not make me want to throw the ball hard. Tossing was all right, but anytime I put force on the ball, it hurt.

"Every day you wake up and expect it to feel perfect, and I don't know if I was surprised by the pain because I could feel it every once in a while, but you always go in hoping it's just going to be minor or a soreness, and then when it turns out to be something a little more serious you're always disappointed."

Magnuson, who was transferred to the 60-day DL on Aug. 23, was in the midst of his third stint with the A's this season at the onset of his injury. Last recalled on July 27, the right-hander made six appearances thereafter, surrendering four earned runs in a combined 8 1/3 innings, for a 4.32 ERA.

The 26-year-old hurler has taken to advice from the likes of Dallas Braden and Rich Harden, both of whom have dealt with shoulder injuries.

"Patience, that's the biggest thing," he said. "I had some really good glimpses of what I think I can do for the team, and that was pretty exciting, so I'm holding on to that."

Worth noting

• Jemile Weeks, back in the lineup after missing two games with left leg soreness, made his first career start in the No. 2 hole on Friday, while Coco Crisp was in the leadoff spot.

"I don't want Weeks to feel like he has to push it right away," manager Bob Melvin said. "Coco can hit anywhere in the lineup, so just a minor tweak, and we'll see where it goes from today."

• Scott Sizemore has been dealing with some shoulder tendinitis, Melvin said, and was given the night off Friday. Eric Sogard started in his place at third base, but Melvin noted Sizemore "certainly could play."
