Top of the second inning last night, Indians shortstop Jhonny Peralta hits a ball to Mariners shortstop Yuniesky Betancourt. Here’s what happens:

Always keep the ball in front of you!

That play didn’t work out so well for Yuni. Peralta was safe at first. Yuni quickly rebounded, and made an awesome throw to ensure Peralta and Shin Soo Choo were doubled up on Choo’s weak grounder. That double play means Yuni’s error didn’t really happen and doesn’t count.
Except in statistics.

In the bottom of the second, right after Yuni gets on base without the benefit of swinging (Aaron Laffey hit his foot), Ichiro hits a ground ball to Peralta. Here’s what happens:

Turnabout!

Jhonny Peralta let that ball pass right by him, too. The Mariners went onto score 5 runs that inning, and are now PERFECT (for at least the next two hours) after the All-Star break.
If Yuni can keep making errors that inspire other shortstops to goof, I think the M’s can sustain some success.
