Farrell being cautious with Frasor's workload

BOSTON -- In his fourth game back, free-agent-to-be Jason Frasor got some work in.

After a month and half away because of tightness in his throwing forearm, the right-hander returned with 1 1/3 scoreless innings to end Saturday's 9-2 win over the Red Sox at Fenway Park. The 35-year-old faced five batters, struck out two and gave up one hit on 25 pitches, just eight of which were balls.

"We wanted to be careful with an up and down [pitching across multiple innings], but he felt great and threw the ball as you saw," manager John Farrell said.

Before the game, Farrell said part of the logic that had kept Frasor out of action was that he wanted to find the right situation for him having not pitched in a big league game since July 16.

"Frasor's been a very good reliever for a long time and still has a lot of pitching left in him," Farrell said. "The fact is we've got more options available to us. We're still lining up to win every single night and yet his situation, his coming back, we want to get him where he's got his feet back on the ground, regardless of the stage in his career. But there's no lack of confidence in getting him on the mound."

Happ surprised he broke his right foot

BOSTON -- Left-hander J.A. Happ was back with the Blue Jays on Saturday, a day after it became known he was headed for season-ending surgery.

Happ will have two screws placed in his right foot to repair a fracture when he visits Dr. Robert Anderson in Charlotte, N.C., likely some time next week. Happ wore a boot on his foot Saturday and said the severity of the injury surprised him just as much as everyone else.

"Yeah, I was definitely surprised," Happ said. "I was feeling something in there. I wasn't sure exactly what it was, but I didn't think that it would be broke."

When exactly it broke still isn't clear. The working theory is that when he broke off the mound to cover first base in his second-to-last start, Aug. 29 in New York, there was some damage done. But the fracture may well have occurred gradually.

"It could've been something that started small and maybe in New York got bigger," Happ said. "The initial break over there [from the mound] is when I felt it. It wasn't the running or hitting the bag."

Happ said he'll be ready for Spring Training and that the foot will be non-weight bearing for about four to six weeks, leading into the rehab process. He and manager John Farrell talked Saturday about the positives Happ showed, and Farrell wanted to reinforce that Happ's time in the rotation wasn't looked at as an experiment.

"I feel fortunate that I did have the time here that I did have," said Happ, who went 3-2 with a 4.69 ERA in 40 1/3 innings after Houston traded him to Toronto. "It's certainly frustrating. The way I feel like I've been throwing the ball, I definitely would have loved to have finished this season strong. Unfortunately this is kind of the hand I was dealt. I'm definitely looking forward to going into Spring [Training], and hopefully I've made a good impression."

Lawrie gets scheduled night off vs. Boston

BOSTON -- Brett Lawrie's absence atop the lineup on his second day back was scheduled, manager John Farrell said Saturday.

The third baseman returned from the disabled list Friday and contributed right away after missing a month because of a right oblique injury, but the Blue Jays want to be careful with him. Farrell talked to Lawrie Friday about controlling his on-field intensity when possible, and now the team's being sure to ease Lawrie back in to regular play.

"The fact is he's had just a couple games played, he'll be back in the lineup tomorrow," Farrell said. "He played the night before [in a Minor League rehab game], traveled in here and this was just a scheduled off-day for him."

On Friday, Lawrie went 1-for-5 with a pair of runs scored and led off a 7-5 win over the Red Sox at Fenway Park with a double. Left fielder Rajai Davis hit leadoff for Toronto on Saturday night at Fenway Park.
