Instant replay will be great for game

"He's a really, really good player,'' said third baseman Chris Johnson, who was traded alongside Upton. "He was (in Arizona) for a long time. Anytime you get traded, you want to come back to the place you got traded from and show them what they're missing a little bit, and I think that's what was on his mind."

Martin Prado, who went to the Diamondbacks in the deal, got off to a fast start but hasn't had a lasting impact. He entered the weekend hitting .235 with a .632 OPS.

After starting the season 12-1, the Braves went 10-17, allowing their National League East lead over the Nationals to largely evaporate. But they were home for only 14 of their first 40 games, the fewest in the majors, and were without catcher Brian McCann and right fielder Jason Heyward, who have returned.

"We're in first place and haven't really been healthy," said McCann, who was activated May 6 after offseason shoulder surgery. "It just goes to show you a lot of guys have stepped up and played huge roles. Once we get to full strength and once we get playing with each other for an extended period, our offense will click a little bit more, and we'll win a lot more."

Hold your breath: The Rays say they're relieved David Price was diagnosed with a strained triceps, but they have to be worried about the 5.24 ERA he had when he went on the disabled list. The reigning AL Cy Young Award winner hasn't been himself all season, and the Rays' postseason viability depends on him getting his season jump started when he returns.

"It's new territory for me," the 27-year-old Price said. "I've never really had any arm troubles. … This is frustrating, it is. It's even more frustrating because I'm throwing the ball as bad as I am. That's when you really want to get back out there and get things going in a positive direction."

Manager Joe Maddon doesn't expect Price to miss more than three starts but says the Rays will proceed cautiously.

"When he's well, he's going to be well for a long time," Maddon said. "We have plans of playing in October, and we're not getting there without him."

Hey, old buddy: Rosales, a Chicagoan who attended Maine South before going to Western Michigan, has had a hard time hiding since Hernandez's terrible call that turned a homer into a double May 8.

"I've heard from people I haven't seen since high school," Rosales told the San Francisco Chronicle. "People are interested to see how I feel about it."

Rosales agrees with those who believe that Hernandez twice missing the same call shows why MLB should go the way of the NHL and establish a central office with replay officials. As true third parties to the situation, they could provide impartial rulings passed along to the on-field umpires, who made the calls initially.

Call it the Rosales Rule.

"It's just a missed call,'' Rosales said. "I'm just the one who hit it. It happens, you know. It happened for (Armando) Galarraga in the (near) perfect game. You try to find a way to get it right. You don't have to label it or put a title on it."

Under a cloud: Yasmani Grandal is beginning a 10-day rehab assignment before possibly rejoining the Padres on May 28. He has lost a lot of credibility and standing in the clubhouse as a result of his 50-game PED suspension.

Nick Hundley, the primary catcher during Grandal's suspension, calls him "a guy who is unproven and had a good couple of months on steroids."

The 24-year-old Grandal tested positive for a banned substance and is among the players tied to the tainted Biogenesis clinic in Miami. He hit .297 with eight homers and an .863 OPS in 60 games last year but must prove himself all over again.

"Overwhelmingly, the majority of guys are tired of seeing this," Padres third baseman Chase Headley said, "It's a black eye. We want it out of the game."
