Daily Dose: Texas loses Hamilton, McCarthy

Josh Hamilton's stay on the disabled list was extended Monday, as the Rangers announced that he'll miss another 4-6 weeks after undergoing surgery to repair a partially torn abdominal muscle. Hamilton had been hoping to avoid going under the knife, but decided otherwise when the pain persisted following his trip to the DL last week and a second opinion confirmed the need for surgery.

Hamilton being out has Texas going with David Murphy in left field, Marlon Byrd in center field, and Nelson Cruz in right field, as manager Ron Washington opted for that alignment in seven of the past eight games. That outfield leaves Andruw Jones and Hank Blalock in a fairly strict platoon at designated hitter, with Blalock getting the starts against right-handed pitching.

While the Rangers try to hold onto first place in the AL West sans Hamilton, here are some other notes from around baseball …

* Along with losing Hamilton, the Rangers also discovered Monday that Brandon McCarthy will be sidelined indefinitely with a stress fracture in his shoulder. He'll be completely shut down for several weeks and a similar injury in 2007 kept him out for over a month. McCarthy went 5-2 with a 4.92 ERA and 44/26 K/BB ratio in 11 starts, but this marks his fourth trip to the disabled list in three seasons.

Doug Mathis was called up from Triple-A to step in for McCarthy on Tuesday, but he lacks fantasy upside and ultimately the rotation spot will probably be filled by Derek Holland once Matt Harrison returns from the DL later this week. Holland is just 1-3 with a 6.54 ERA in 31.2 innings, but the 22-year-old southpaw has plenty of potential after posting a 2.68 ERA and 245/64 K/BB ratio in the minors.

* Jeremy Bonderman came off the disabled list and Jose Contreras was recalled from the minors Monday, and they faced off with dramatically different results as the Game 2 matchup of a doubleheader in Chicago. Contreras had gone 0-5 with an 8.19 ERA prior to being demoted to Triple-A last month, but shut out Detroit for eight innings while allowing just one hit and one walk.

Meanwhile, Bonderman struggled mightily in his 2009 debut as Chicago knocked him around for six runs in four innings, including three homers. He struck out just one batter and reports of decreased velocity while rehabbing proved accurate as Bonderman initially threw 88-91 miles per hour before dropping to 87-89 late. For comparison, his average fastball was 92.7 mph from 2003-2008.
