The Washington Nationals selected the contract of infielder Carter Kieboom on Friday. On Thursday, the Nationals optioned infielder Jake Noll to Triple-A Fresno. Additionally, the Nationals transferred right-handed pitcher Koda Glover to the 60-day Injured List. Nationals President of Baseball Operations and General Manager Mike Rizzo made the announcements. Kieboom, 21, joins the Nationals after hitting .379 (25-for-66) with six doubles, one triple, three homers, 18 RBI, 16 walks and 14 runs...

MINNEAPOLIS - The Orioles begin a two-city, six-game road trip tonight at Target Field against the Minnesota Twins. The trip moves to Chicago on Monday for a three-game series against the White Sox. The Orioles are 10-16 overall and 7-6 on the road, winning series at New York against the Yankees and in Toronto. While O's pitchers have allowed 41 homers in 13 home games with a home ERA of 7.38, they have given up many fewer homers away from Camden Yards. They have allowed 18 in 13 road games...

The Orioles completed another round of roster business this morning, keeping a pitcher in their organization who could provide a fresh arm for their bullpen later in the summer. He just needs to get back on the 40-man roster. Right-hander Josh Lucas cleared waivers today and accepted an outright assignment to Triple-A Norfolk. The Orioles optioned Lucas between games of Saturday's doubleheader to create room for Alex Cobb on the 25-man roster and designated him for assignment two days later....

The amazing start to the 2019 season continued last night for Double-A Harrisburg in a 10-7 extra-inning win over Hartford. The Senators scored four runs in the eighth and four runs in the 11th to seal the victory. Harrisburg is a franchise-best 17-3 after 20 games, dating back to 1987. Chuck Taylor went 2-for-2 and drove in four runs after arriving as a pinch-hitter in the eighth. Starter Tyler Mapes allowed only one unearned run in five frames. Dan Jennings tossed 1 2/3 innings and allowed...

When his team suffered a spate of early-season injuries in April 2012, Mike Rizzo made the decision to call up Bryce Harper and give the 19-year-old a chance in the big leagues. Harper never returned to the minors. When his team needed a third baseman in April 2013, Rizzo summoned Anthony Rendon straight from Double-A. Rendon would briefly return to the minors, but by June he was back in the majors for good. When his team needed an offensive boost in August 2015, Rizzo promoted Trea Turner and...

As most young players in the major leagues can tell you, it is great to get to the majors and greater yet to have an everyday role when you make it. The last three years, infielder Rio Ruiz got 288 plate appearances with the Atlanta Braves, and they gave him a bit of a look in the summer of 2017. But in the first month of this season he already has 93 plate appearances, and he's been the everyday third baseman for the Orioles. He's been a solid defender and his bat is trending up. A great...

Carter Kieboom, the Nationals' top prospect off to a red-hot start at the plate with Triple-A Fresno, is getting called up to make his major league debut this weekend, a source familiar with the move confirmed. It's not yet clear what corresponding transaction (or transactions) will be made before Kieboom's contract is purchased. The Nationals not only need to remove someone from the active, 25-man roster but also to clear a spot on the 40-man roster for Kieboom, the organization's first...

The Orioles are back on the road, flying into Minnesota yesterday afternoon with a stop pending in Chicago. They're 7-6 away from home. The Twins swept the Orioles last year in a four-game series at Target Field. Alex Cobb, making tonight's start, walked off the mound in the finale with a blister on his finger. Six games on the road trip led to six defeats, leaving the Orioles 24-65 overall and losers of 13 of their last 14 games. They fell to 41 below .500 for the first time since Aug. 1,...

Showing a new and improved changeup to compliment his fastball that can touch the mid-90s, Orioles 2018 first round draft pick Grayson Rodriguez is off to a stunning start to his 2019 season. The 19-year-old right-hander is 3-0 with an ERA of 0.54 in three starts for the Single-A Delmarva Shorebirds. Over 16 2/3 innings, he has allowed seven hits and one run with six walks and 28 strikeouts. He has a WHIP of 0.78 versus South Atlantic League hitters. Because Rodriguez is a young pitcher in his...

DENVER - They've been putting this off for several weeks now, hoping beyond hope things would get better and they could proceed as they intended all along. But the time has probably come for the Nationals to do something with Trevor Rosenthal. They can't afford to keep waiting and keep hoping. They've put Rosenthal on the mound seven times in the last month. They've yet to see him come anywhere close to throwing a clean inning of relief. Even though there were some legitimately encouraging...
