KANSAS CITY, MO. – Twins manager Paul Molitor chooses his words very carefully when discussing his outfield defense.
"You're mostly trying to find some things out," Molitor said. "Unfortunately you have to suffer through some of the mistakes along the way as we try to evaluate where these guys are at with their careers and what they can do on defense."
That came one day after more misplays in the outfield cost the team runs. Thursday, center fielder Eddie Rosario made an ill-advised throw when he had little chance to get Lorenzo Cain at third. On top of that, he threw wildly, enabling Cain to score.
The next batter, Kendrys Morales, sent a fly ball to left that Robbie Grossman made a poor read on, which led to a gift double.
Grossman has a plus/minus rating of minus-18 as a left fielder. Plus/minus is a measure of many plays a defender makes that are above or below what an average fielder would make.
Rosario entered Friday with a minus-2 rating in left and minus-3 in center, where he is currently filling in for the demoted Byron Buxton, who is regarded as an excellent defensive center fielder.
Max Kepler was a plus-2 in right field. Miguel Sano was minus-13 before he was moved to third base.
Kepler has made solid progress defensively. Rosario racked up 16 assists last season, playing mostly in left. He has five this season. Grossman probably is the least-gifted defensively among Twins outfielders. He doesn't throw as hard as the others but tries to get off quick and accurate throws. But his routes haven't been the most direct at times, with Thursday's play being one of the worst.
