Michael Pineda made his major league debut on Tuesday against the Texas Rangers, and a lot of people are really high on his potential.
Signed: International free agent, 2005
Ranked by Baseball America as the No. 16 prospect in baseball for 2011.
While many think some further seasoning in Tacoma would have done him and the team well, they also believe he has real major-league talent and could learn on the fly while providing the Mariners with much needed immediate value.
He did nothing last night to prove he doesn't belong.
His offense didn't help much, and you could certainly question Eric Wedge's decision to let Pineda pitch to reigning AL MVP Josh Hamilton with first base open. However, when he did struggle, it was against the left-handed bats to the tune of three extra base hits, which resulted in the runs scoring that cost him the game.
There's no question that the young man has room to improve, but there's also no question that he has the legit makeup to be a quality big-league starting pitcher.
With that, here's a look at the other most hyped Mariners prospects since 1990 (with an exception for Griffey Jr., drafted in 1987).
