O's right-hander Ubaldo Jimenez thinks the key to getting on track is being aggressive.
Jimenez, who is still looking for his first quality start this season, will face the Red Sox for the second time this year on Sunday night, and the righty has been watching a lot of video from 2014 and past seasons.
"I'm kind of slow going to home plate," Jimenez said. "I'm not very aggressive. I'm kind of babying the ball instead of being aggressive. That's something I've been working on.
"[Pitching coach] Dave [Wallace] and [bullpen coach] Dominic [Chiti] and me, we watched video and we saw it right away what was wrong, and [we're] trying to make it better. Video of last year, two years ago. Saw them the whole week. I always watch videos because I want my mechanics to be consistent, but the last thing you want to do is be thinking of mechanics, but when everything is not working like it's supposed to, you have to watch more to find why it's not working."
Jimenez has posted a 7.31 ERA in his first three starts, allowing 13 earned runs over 16 innings. It's not exactly the start he or the Orioles (8-8) envisioned when he signed a four-year, $50 million contract -- the organization's largest commitment to a free-agent pitcher -- in February.
"I didn't start like I wanted to, but I know everything is going to change," said Jimenez, who was encouraged by the adjustments he made in his last work day."... I know everything is going to click, it's just a matter of time."
Jimenez went six innings and allowed five runs in a loss to the Red Sox on April 2, allowing five hits with three walks. He will be opposed by righty Jake Peavy, who has pitched well despite not earning a decision on the season, allowing just four earned runs over 18 2/3 innings. The four-game series is tied after Boston's 4-2 win on Saturday afternoon improved the Red Sox to 8-10 on the season.
"As a team we got to figure out a way to win a few more of these games, and I think we will," Peavy said of Boston's slow start. "The biggest thing is we got to get healthy. We're still coming together, still getting to know each other, getting used to playing with some new faces. But personally I feel good, and just going to try to give my team a chance to win every time it's my day."
Red Sox: Victorino plays first rehab game
Shane Victorino, who has been on the disabled list all season after straining his right hamstring in the final Spring Training game, went 0-for-3 in his first rehab game for Triple-A Pawtucket on Saturday. He played right field for six innings.
Victorino will get an off-day on Sunday and then play for Pawtucket again Monday and Tuesday. The Red Sox will re-evaluate his progress at that point.
Victorino was also slowed by a bout of the flu, which caused him to lose 8-12 pounds, while he was on the DL.
O's: Machado plays in first extended spring game
Orioles third baseman Manny Machado went 2-for-4 over five innings in his first extended spring game on Saturday morning.
Manager Buck Showalter said the report on Machado, who also played the field, was good, and the plan is for the 21-year-old to take his scheduled off-day on Sunday before playing seven innings at third base on Monday. Machado will serve as designated hitter on Tuesday.
Assuming he sticks to the plan, Wednesday would be the earliest date for Machado to start his rehab assignment. The Orioles are optimistic when he does go to a Minor League affiliate that he won't need the full 20 days allotted since Machado has been doing baseball activities for months.
Machado is rehabbing back from left knee surgery in October.
• Prior to Sunday's game, the Red Sox will commemorate the one-year anniversary of last year's Boston Marathon tragedy. The University of Massachusetts marching band and Boston Pipers Society will perform a piece called "Highland Cathedral," as well as the national anthem. Members of the Boston Police Department, Watertown Police Department and Massachusetts State Police will carry the colors.
