Second to none (w/injury updates)

Injury updates: MASN's Amber Theoharis tells me that closer Mike Gonzalez will head to the minor league camp in Sarasota to begin a three-week rehab assignment. It'll be a while before he's attempting to close games again. Manager Dave Trembley told reporters in Oakland that Jim Johnson most likely would receive the bulk of the save opportunities. Kam Mickolio will work at the back end of the bullpen, giving Trembley a power arm late in the games. Also, Koji Uehara is scheduled to face live hitters on Saturday after throwing another bullpen session. So much for Julio Lugo getting most of the starts at second base in Brian Roberts' absence. Ty Wigginton is in the lineup again tonight, with Lugo taking a seat on the bench. Trembley keeps choosing the bat over the glove, which happens when so many hitters have been slow out of the gate. Wigginton's hitting .333 with two homers and a .667 slugging percentage. Lugo's hitting .118 with a slugging percentage to match. Down on the farm, last year's first-round pick, Matt Hobgood, is shutting out Single-A Greensboro on three hits over five innings. He's struck out three and walked none, and Delmarva is holding a 6-0 lead. Hobgood update: Hobgood allowed two runs and six hits in 5 2/3 innings. He struck out four and walked none. T.J. Baxter has homered twice and driven in four runs. Triple-A Norfolk's Rhyne Hughes has doubled twice and driven in a run, raising his average to .435 and extending his hitting streak to seven games. He's serving as the designated hitter tonight, but has made five appearances in the outfield this season. Double-A Bowie's Chorye Spoone has held Akron to one run and three hits over six innings. He's walked four and struck out one.
