TEMPE, Ariz. — By his own admission Don Mattingly hasn't spent a lot of time thinking about baseball's two newest rules, one allowing the use of instant replay and the other preventing catchers from blocking the plate if they don't have the ball.
But the manager of the Dodgers has a new appreciation for both changes after they collided in the first inning of Thursday's 4-4 Cactus League tie with the Angels.
After Mike Trout's one-out line drive squirted under a diving Yasiel Puig and rolled to the center-field wall, Trout tried to circle the bases, only to arrive back home at the same time the ball did. Umpire Gerry Davis called Trout out, sparking an immediate protest from Angels Manager Mike Scioscia, who had problems with both the call and catcher A.J. Ellis' position on the play.
"When Trout touched third base Scioscia was already coming out to challenge it," Dodgers pitcher Dan Haren said. "I knew he was going to come out."
Mattingly, however, wasn't sure what was happening.
"It's interesting because it seems like everybody has a different take," he said. "Mike's kind of interpreting it one way. Talking with the umpires, it's kind of coming back a little bit different. It's going to be a little bit crazy, I think. Especially that play at home plate."
This time Scioscia lost on both counts. First the umpires went to the video to check Ellis' positioning, something managers cannot challenge. But while determining that the catcher was inadvertently drawn into the runner by Hanley Ramirez's throw from left field — which is legal — they also checked the tag, which got Trout before he touched the plate.
"Procedurally, we're hopefully starting to understand this replay a little bit more," Scioscia said. "As it was, I didn't use a challenge because of the crew chief's ability to look at a play at the plate."
The official time of the review was 72 seconds.
The Dodgers say they hope to have a better sense of how replay will work after they meet with a delegation of umpires this weekend.
"There's not as much clarity as I would like," Haren said. "We're having a meeting to kind of iron out some things. Because we're just as confused as the fans are really.
"Nobody's really sure about it yet."
Zack Greinke, who came out of his first spring start last week with a mild strain in his right calf, threw about two dozen pitches off a mound Thursday morning and could start throwing to hitters this weekend.
Outfielder Matt Kemp was also progressing in his rehab, stepping up his running program and taking batting practice. Kemp, who had surgery on his left ankle last fall, is still running straight ahead but the medical staff hopes to have him trying turns and cuts soon.
Neither Kemp nor Greinke is expected to make the team's season-opening trip to Australia later this month.
