Luis Arraez battled tendinitis in his left knee all the way back to summer camp in July.
When he sat out a couple of games in early August because of the same ailment, the Twins described the injury as very minor.
But Arraez continued to tweak it each time he returned from a day or two off. It's now at the point where it no longer is a very minor issue, it's an injured list issue.
The Twins placed their second baseman, and one of the best at-bat takers on the team, on the 10-day injured list as a way to get Arraez healthy instead of nursing him through an ailment that was forcing him to the bench every few games.
"Not an easy call," Twins manager Rocco Baldelli said, "but even after the day off and then he came in and worked out yesterday, the improvement with even some days off did not seem big enough to where we were getting to the point where we could lean on him or rely on him to play regularly.
"We want him to be able to play regularly, not go out there and be just a piecemeal, complimentary type player that plays a few innings and you have to get him out of there."
With the Twins heading into the stretch drive — the playoffs are less than three weeks away — they want to get Arraez as healthy as possible. Then again, the Twins could have shut down Arraez earlier in the season when he started to aggravate the knee. They could have had him healthy for this week, as they enter the three-team gantlet of Indians, White Sox and Cubs.
But Arraez and the Twins both thought it he was well enough to play. Until now.
