• Center fielder Franklin Gutierrez ran well in a workout on Wednesday at Safeco Field and could be ready to begin an injury rehab assignment with Triple-A Tacoma as early as Thursday or Friday, according to Wedge. Gutierrez is on the 15-day disabled list with a strained right hamstring.
• Right-handed reliever Josh Kinney, who is eligible to come off the 60-day DL on May 30, will make his first rehab appearance on Friday for Tacoma, Wedge said. Kinney sustained a stress reaction in his ribs during Spring Training and has been throwing at extended spring camp in Arizona over the past few weeks.
• Blake Beavan picked up his first win for Tacoma on Tuesday after throwing six innings of two-run ball. The right-hander gave up six hits while walking one and striking out four in a 4-2 win at New Orleans. He's 1-2 with a 4.86 ERA in three starts since being sent down.
• Taijuan Walker -- the Mariners' No. 1 prospect, according to MLB.com -- allowed just four hits and one earned run in seven innings on Tuesday but took a no-decision as Double-A Jackson fell to Tennessee, 3-2. Walker struck out six and walked one. He's 3-3 with a 2.09 ERA in eight starts this season.
• When Charlie Furbush let a 3-1 lead get away on Tuesday night, it was just the second blown save by the Mariners this season. The Rangers, who have yet to blow a save this season, are the only team in the Majors with fewer than two blown opportunities.
