The Orioles transferred Mateo (hamstring) from the 10-day injured list to the 60-day IL on Sunday.

EDGE Analysis

Initially placed on the IL on June 7 due to left elbow inflammation, Mateo was on the cusp of returning before he suffered a significant left hamstring strain during a rehab game with Triple-A Norfolk last Sunday. The Orioles are expecting him to miss two or more months due to the hamstring injury, so his move to the 60-day IL won't affect his return timeline. The transaction opened up a spot on the 40-man roster for catcher Alex Jackson, acquired from the Yankees on Sunday.

Mateo was diagnosed with a strained left hamstring Tuesday and is expected to miss 8-12 weeks, Roch Kubatko of MASNSports.com reports.

EDGE Analysis

Mateo landed on the injured list in early June due to elbow inflammation. However, after suffering a hamstring injury during a rehab game at Triple-A Norfolk on Sunday, it now seems likely that his absence will extend into September. As a result, Luis Vazquez, who was selected from Triple-A as Mateo's roster replacement, will likely remain with the big club as bench depth for the foreseeable future.

Mateo (elbow) was pulled from a rehab game Sunday with Triple-A Norfolk due to a hamstring issue, Andy Kostka of TheBaltimoreBanner.com reports.

EDGE Analysis

Mateo has been working his way back from left elbow inflammation and was participating in his fourth game of a rehab assignment before sustaining the setback. He's expected to undergo further evaluation in the coming days, so be on the lookout for an update on the severity of the injury.

Mateo (elbow) told reporters Wednesday that he has participated in all baseball activities and is expected to begin a rehab assignment with Triple-A Norfolk, Matt Weyrich of The Baltimore Sun reports.

EDGE Analysis

Mateo reported to Norfolk on Tuesday while continuing to build back up from left elbow inflammation that caused him to be placed on the 10-day injured list June 10. Mateo sported a .510 OPS with 14 steals, three doubles, one home run and three RBI in 65 plate appearances with the Orioles prior to landing on the IL.

Mateo (elbow) is set to begin a minor-league rehab assignment at Triple-A Norfolk on Tuesday, MLB.com reports.

EDGE Analysis

Mateo is entering the final stages of his recovery from left elbow inflammation. The 30-year-old speedster has a chance to rejoin Baltimore's roster before the end of June, but he should be able to return in early July at the latest. Mateo primarily served as a pinch runner and defensive specialist prior to going down, having slashed .180/.231/.279 with one home run, three doubles, three RBI and 14 stolen bases over 65 plate appearances.

Interim manager Tony Mansolino said Friday that Mateo (elbow) has resumed baseball activities and is nearing a rehab assignment, Jake Rill of MLB.com reports.

EDGE Analysis

Mansolino didn't specify a target return date for Mateo, but a return to baseball activities is still a significant step forward for the 29-year-old, who has been out since early June with elbow inflammation.

The Orioles placed Mateo on the 10-day injured list, retroactive to June 7, due to left elbow inflammation.

EDGE Analysis

Mateo missed the last two games for Baltimore and his absence will now extend until at least June 17. In a corresponding move, the Orioles selected Luis Vazquez from Triple-A Norfolk.

Mateo went 1-for-1 with two walks, a two-run home run and two stolen bases in Saturday's 4-2 win over the White Sox.

EDGE Analysis

Getting the start in center field and batting ninth, Mateo looked like he might be the latest Baltimore outfielder to land on the injured list when he appeared to hurt his arm in a collision with Heston Kjerstad in the eighth inning. Mateo stayed in the game however and proved he was OK by swiping his second bag of the game in the bottom of the frame. That capped a huge performance from the utility player that included his first long ball of the campaign, a fifth-inning shot off Davis Martin, and his first game with multiple walks in over a year. Mateo has started five of the Orioles' last nine games -- three in center field, one in left and one at shortstop -- and he's gone 5-for-17 (.294) over that stretch with seven of his 14 stolen bases on the season.

Mateo went a combined 1-for-4 with a walk, two stolen bases and a run across both games of a doubleheader split against the Red Sox on Saturday.

EDGE Analysis

Mateo began Game 1 on the bench but entered as a pinch runner in the eighth inning, reaching second on a stolen base before striking out in his lone plate appearance in the 10th. He got the start in center field in the nightcap and played a key role on offense, drawing a walk in the ninth inning before stealing second base again and subsequently coming around to score the decisive run on a Dylan Carlson double. Mateo is slashing just .209/.244/.279 on the season with no home runs and only one RBI through 45 plate appearances, but he's been able to make some impact with his speed, notching nine thefts on 10 attempts.

Mateo went 2-for-3 with two stolen bases in Sunday's loss to Detroit.

EDGE Analysis

Sunday marked the first multi-hit game of the season by Mateo, who also swiped a pair of bags for the second time in 15 appearances so far. The speedy 29-year-old is still batting just .136 with a lone extra-base hit and one run scored over 22 at-bats, but he does have five steals while operating primarily as a pinch runner for the Orioles.
