The Kids Are On Their Way As Rosters Expand

The kids are coming, and when the Major League rosters expand on Monday, Mariners minor leaguers will be coming two at a time.

Although a handful of Tacoma players are expected to join Seattle during the next 7-10 days, only two will join the Mariners in Texas tomorrow – left-handed pitcher Justin Thomas and second baseman Luis Valbuena.

For Thomas, 24, and Valbuena, 22, this will be their first trip to the big leagues.

In the days that follow, the Mariners expect to call up catcher Rob Johnson and pitchers Brandon Morrow, Mark Lowe and Jarred Wells.

Thomas and Lowe will work out of the bullpen. Morrow will slide into the starting rotation against the New York Yankees in Seattle next week and Johnson – who'll become the fourth catcher on the roster – will probably get a few spot starts behind the plate.

Valbuena will pinch run and occasionally play in the field.
