Infielder Matt Antonelli has retired from baseball. The report comes from MLBDailyDish.com's Chris Cotillo, who says Antonelli will become a student assistant next season at Wake Forest, where he went to college. A former first-round pick, Antonelli made it up to the majors for 21 games with the Padres in 2008 but had not come close to sniffing the big leagues since.

Indians released INF Matt Antonelli. Antonelli, who joined the Indians this winter on a minor league deal, went 0-for-6 in three games with Triple-A Columbus. The 28-year-old will attempt to latch on elsewhere.

Indians signed INF Matt Antonelli to a minor league contract. The former first-rounder hasn't appeared in the majors since 2008 and is coming off a horrid showing in 2012, having batted .201/.324/.286 over 44 games at Triple-A for the Orioles and Yankees. He's merely organizational depth.

Yankees released INF Matt Antonelli. Antonelli was designated for assignment earlier this week to clear a roster spot for Chad Qualls. The 27-year-old infielder will try to latch on with a new club.

Orioles designated INF Matt Antonelli for assignment. Antonelli failed to earn a roster spot out of spring training and is off to a .204/.357/.280 start at Triple-A Norfolk. He should clear waivers and remain in the organization.

Orioles optioned INF Matt Antonelli to Triple-A Norfolk. Antonelli had a chance at a utility infield job this spring, but batted just .194 (6-for-31) with zero extra-base hits. Ryan Flaherty now appears to be in good shape to make the Opening Day roster.

Orioles signed INF Matt Antonelli. The deal was agreed to late last week, then made official on Monday after Antonelli passed his physical in Baltimore. The 26-year-old infielder batted .298/.390/.457 in the minor leagues last year and will now serve as organizational depth for the Orioles.

Brittany Ghiroli of MLB.com reports that the Orioles have signed infielder Matt Antonelli, pending a physical. He is expected to receive a big league deal, according to Dan Connolly of the Baltimore Sun. Antonelli, who turns 27 next April, batted .298/.390/.457 with eight homers, 31 RBI and an .847 OPS over 374 plate appearances this season between Double- and Triple-A in the Nationals' organization. He hasn't appeared in the big leagues since 2008 as a member of the Padres and is unlikely to crack the O's Opening Day roster.
