UPDATE: Twins manager Ron Gardenhire was pleased with the signing, because Perez has a career 1.89 ERA in 41 games against them. Joe Mauer approved of the signing too.
``He hides the ball well,'' Mauer said.
Caution is needed here. Shoulder surgeries can be tough to come back from. But if Perez is all the way back, he could be a valuable middle relief option. For more info on Perez's surgery, check out this story.
The Perez signing was the biggest news on a day in which the Twins had to move their work indoors to avoid the rain. Some drills had to be scratched, but the pitchers got their work in, which is important.
Some quick observations:
Jared Burton and Darin Mastroianni are in fantastic shape.
Josh Roenicke is a reliever to watch in camp. Roenicke posted a 3.25 ERA with Colorado last season despite a high walk rate. There's also Tim Wood, a two-time International League reliever of the year. Both players are out of options
Brian Dozier is switching his uniform number from No. 20 to No.2. ``No. 20 didn't work out too well for me last year,'' he said. ``Maybe I can get some of that Denard Span magic.''
