Oakland A's MLN: Roster Changes

The movement within the Oakland A's system has continued this week. We detail some recent moves, including one involving a top relief prospect and another involving one of the A's top infield prospects...

A number of Oakland A's prospects have changed rosters or have moved on or off of the disabled list this week. We detail some of the changes below...

Jared Lansford: It has been a struggle all season long for Lansford, who is one of the A's top relief prospects. In 11 innings for Triple-A Sacramento this season, Lansford has allowed 11 earned runs on 13 hits and 12 walks, while striking out only one. Thus far, it doesn't appear that injury is the reason behind Lansford's woes. He is currently back in Phoenix at extended spring training, working with roving pitching and rehab coordinator Garvin Alston, who was also Lansford's pitching coach in Stockton last season. According to A's Director of Player Development Keith Lieppman, Lansford is working with Alston on mechanics and delivery and should be back with Sacramento soon.

Adrian Cardenas: The A's top middle infield prospect was sent back to Double-A Midland on Thursday. Cardenas hit only .177 with a 512 OPS in 18 games with the Triple-A Sacramento River Cats. He returns to Midland, where he hit .372 wtih a 1033 OPS in 19 games before his promotion to Sacramento. The reasons for Cardenas' demotion to Double-A were a combination of a few factors, according to Lieppman: 1) the River Cats' roster was crowded with infielders (Cliff Pennington, Eric Patterson, Gregorio Petit and Jeff Baisley) and the River Cats' outfield became more crowded this week with the additions of Aaron Cunningham and Chris Denorfia, making it harder for Patterson to see time in the outfield, thus limiting the at-bats available in the infield; and 2) that Cardenas was struggling.

Chris Denorfia: The aforementioned Denorfia returned from the disabled list for Sacramento on Thursday. The centerfielder went 1-4 with a double in his return to the line-up. He missed nearly three weeks with a hamstring strain. With Rajai Davis struggling with Oakland, Denorfia could get a look in the big leagues soon if he is swinging the bat well over the next few days.

Scott Moore: Right-hander Scott Moore has been out all season with a sore elbow. That elbow will require Tommy John surgery, which will leave him on the shelf for the rest of the year and some of next season. Moore is scheduled to have the surgery next week. He threw 102.2 innings for Kane County, Stockton and Midland last season.

Josue Selenes: Reliever Josue Selenes has been placed on the Kane County DL with a right elbow strain. Selenes, a minor league Rule 5 pick from the Yankees, was 4-1 with a 4.15 ERA and 15 strike-outs in 17.1 innings for the Cougars. Reliever Jose Guzman has been activated off of the Cougars' DL to take Selenes' spot on the roster. Guzman was on the DL with a back injury.

Arnold Leon: Midland reliever Arnold Leon has been placed on the DL with a right elbow strain. The Mexican native has a 4.35 ERA and a 17:11 K:BB ratio in 20.2 innings this season. Because of his time in the Mexican Winter League during the past two off-seasons, Leon has been pitching almost full-time for the past two years. The 20-year-old last pitched on May 14th.

Joel Galarraga: Galarraga, who like Leon was acquired by the A's from the Mexican Summer League, is on the Sacramento DL with a shoulder strain. The catcher had been red-hot since joining the River Cats from extended spring training on May 6th. He was batting .357 with a 925 OPS in 13 games with Sacramento. Anthony Recker was called up from Midland to replace Galarraga on the Sacramento roster.

Mitchell LeVier: LeVier, an outfielder with the Kane County Cougars, is experiencing elbow soreness in his throwing arm. The soreness dates back to a pitching appearance he made with the Cougars earlier in the season. He is scheduled for an MRI this weekend.
