Vitals: 29 yo LHP. Born in Wichita, KS. 6-2, 225. 36-43, 4.44 career. 3-1, 2.48 in 2007. $3.26 million salary.

Arsenal: Low-90s fastball, slider, change that runs away from righties.

Recent Battles: Robertson held the Mariners to one run in seven innings last September, beating Jarrod Washburn.

Our Best Weapon: Righties hit Robertson well. If Ibanez needs a day off, this might be a good game to start little-used Jason Ellison.

The Internet Says: Robertson invented "Gum Time," a sister to the rally cap. When the Tigers need a rally, you throw a bunch of Big League Chew in your mouth.

Cha Seung Baek (0-0, 7.53) goes for the M's. Gametime is 4:05. It's on FSN
