Izturis exits with groin strain

BALTIMORE -- Second baseman Cesar Izturis left following the fourth inning of Sunday's game against Toronto with a left groin strain. The 31-year-old, who was replaced at second by Blake Davis to start the fifth, was making his second start with Baltimore since coming off the 60-day disabled list with right elbow surgery.

Iztruris is batting .200 in 30 at-bats this year with an RBI. He did not show any physical signs of pain during the game that would indicate that the injury stemmed from any one play.

Hardy, Davis could return to lineup on Monday

BALTIMORE -- The Orioles received good news on Sunday as a CT scan of J.J. Hardy's left ankle and an MRI on Chris Davis' right shoulder each revealed no structural damage. Both players hope to return to the starting lineup on Monday against the White Sox.

Both infielders were sidelined for Baltimore's three-game series against the Blue Jays, despite saying they were experiencing minimal to no pain. Davis said his shoulder has "a little bit of damage to the rotator cuff and labrum ... just some wear-and-tear from over the years of throwing," while scans on Hardy did not reveal any injury other than soreness.

"Yeah, [Davis and Hardy are] progressing well and excited about what we got back from the CT scan and MRI," manager Buck Showalter said. "[We] feel like it's pretty imminent that they're back on the field shortly."

Hardy and Davis rested on Sunday and will test the ankle and shoulder, respectively, prior to Monday's 7:05 p.m. game. Both could play if they don't experience any problems.

"It was good news, definitely," Hardy said. "[There's] nothing wrong with the bone structure or anything with the bone. Looks like, take another day kind of easy today, don't test it, really, and hopefully tomorrow test it, and if it feels good, I'll play."

In their absence, the Orioles have been forced to use a reworked infield, with slugger Mark Reynolds moving from third to first and Robert Andino filling in at shortstop. In the first two games of their series against Toronto, the Baltimore defense has been solid, committing no errors and turning two double plays in Saturday's 6-2 win.

Showalter said he likes having a versatile infielder in Reynolds, who made some impressive scoops at first on Saturday en route to 11 putouts.

"[Reynolds] has played a good number of games at first base in the big leagues, and it was something that we talked about -- the 'what-ifs' -- in the offseason when we traded for Mark," Showalter said. "I just look at it as a luxury to have two guys who can play first and two guys who can play third in Chris and Mark."

Matusz showing progress at Norfolk

BALTIMORE -- Brian Matusz has taken a long and winding road to reach this point in the season. From the disabled list, to the Baltimore rotation and now with Triple-A Norfolk, Matusz has not had the same success he experienced last season as a rookie.

His journey took a turn in the right direction on Saturday night, as Matusz got his first win this season for Norfolk, completing seven innings and allowing one earned run on five hits, with two walks and six strikeouts, in a 9-1 win over Rochester. The quality start comes on the heels of another seven-inning outing on July 31 in which Matusz gave up three earned runs on six hits, including two home runs, while striking out two and walking a batter.

"He got hit with a ball in the ankle early on last night, but continued on through seven," manager Buck Showalter said. "It's better, a little bit better each time out. [Matusz] looked a lot better physically, too, on the mound, from the pitches I saw."

After a strained left intercostal muscle landed Matusz on the disabled list for much of the first half of the season, the young left-hander went 1-4 with a 8.77 ERA in six June starts with Baltimore. The tough start to the season forced the Orioles to send Matusz back down to Norfolk, where he is 1-3 with a 4.14 ERA in eight starts with the Tides.

Ironically, Saturday night was also Brian Matusz bobblehead night at Camden Yards.

Worth noting

• Left-hander Jo-Jo Reyes threw a bullpen session on Sunday and will likely make a spot start Tuesday instead of Zach Britton.

• Jake Arrieta was placed on the 15-day DL with a bone spur in his right elbow on Saturday night to make room for starter Chris Tillman. Arrieta will see orthopedist Dr. Lewis Yocum on Wednesday in California, where he could get the news that he needs season-ending surgery

• The Orioles won on Saturday, despite garnering just four base hits. The only other time Baltimore has won this season with four or fewer hits was May 22 at Washington.
